Description

Technical Field

[0001] The present invention relates to a method and apparatus for manufacturing construction aggregates from virgin materials and recycled materials.

[0002] Background Art The use of recycled materials in construction is gaining popularity as a sustainable and cost-effective alternative to traditional construction aggregates. The use of concrete containing recycled materials includes environmental benefits, cost reduction, durability, and a reduction in the demand for virgin materials. In the context of resource extraction and environmental sustainability, the use of virgin materials is often scrutinized because their extraction and processing can impact the environment. As a result, there is an increasing emphasis on recycling and reusing materials to minimize the need for virgin material extraction. The separation of recycled materials and subsequent supply of virgin materials can also lead to resource depletion, habitat destruction, and higher energy consumption. The use of concrete made from a mixture of recycled and virgin materials has been shown to be a viable option for a wide range of construction applications, including roadways, bridges, and buildings. Concrete containing recycled materials reduces the amount of waste sent to landfill, resulting in a reduction in greenhouse gas emissions and conservation of natural resources such as gravel, water, and energy. Using concrete containing recycled materials as construction aggregates can be more cost-effective than using new materials because it can reduce the need for new materials and transportation costs. Concrete containing recycled materials can be as durable and strong as new concrete, making it a suitable alternative material for various construction applications. The use of recycled concrete reduces the demand for virgin materials, which can help conserve natural resources and reduce the environmental impact associated with the extraction and processing of these materials. Overall, the use of recycled materials is a sustainable and cost-effective option for construction projects, providing many benefits to the environment and economy.

[0003] When recycled materials are used as building aggregates, only coarse aggregates >4mm or >2mm are used. Therefore, aggregates <2mm or <4mm are separated and removed from the recycled materials in a separate processing step. The separated fractions are then transported away and landfilled. For the production of recycled concrete and / or concrete, virgin material with a particle size <4mm must be added to the concrete aggregate. Therefore, the processes known in the art are not cost-effective, inefficient, energy-efficient, environmentally friendly, unsustainable, or produce good quality.

[0004] Summary of the Invention The problem that this invention aims to solve is to provide a method and apparatus for producing high-quality, cost-effective, efficient, energy-efficient, environmentally friendly, and sustainable building aggregate for use in concrete.

[0005] The solution to the problem is described in the independent claim. The dependent claims relate to further improvements to the invention.

[0006] This invention is based on the observation that it is undesirable to separate and remove aggregates <2 mm and / or <4 mm from recycled materials, because the fractions removed in this process must be transported, landfilled, and exchanged for expensive virgin sand in the manufacture of concrete aggregates.

[0007] The first embodiment relates to a method for manufacturing building aggregates. Building aggregates may include at least one material such as sand, gravel, crushed stone, and recycled concrete. Building aggregates may be mineral or mineral aggregates.

[0008] According to this method, the first material and the second material are mixed. The first material can be washed together with the second material in at least one washer. Washing the first material together with the second material in at least one washer has the effect of removing the washable components of both the first and second materials together in the same process step. Washable components, if present in large quantities, can adversely affect concrete. Therefore, the removal of washable components is important for the quality and usefulness of building aggregates. Washing the first material together with the second material in at least one washer also has the advantage of removing the washable components of both the first and second materials together, resulting in a homogeneous material with homogeneous material properties. These properties are also important for the quality of building aggregates. Washing the first material together with the second material in at least one washer can also improve the quality and usefulness of the material and ensure that the material meets the desired quality standards for further processing or final use. Furthermore, there is no need to remove, transport, and / or landfill materials other than those that can be washed, and there is no need to supply additional virgin materials. This minimizes the use of virgin materials, as well as the need for landfill and / or transport of materials, and therefore minimizes resource depletion, habitat destruction, and energy consumption. Thus, this process is cost-effective, efficient, energy-efficient, environmentally friendly, and sustainable without sacrificing product quality. Efficiency and energy efficiency are factors that play a significant role in being environmentally friendly and sustainable. Therefore, improving efficiency and / or energy efficiency also always means improving being environmentally friendly and sustainable.

[0009] A washer can be a means for purifying and / or washing a material with a liquid medium, such as water. A washer as used herein can be a device used to purify and remove impurities or washable components, such as clay, loam, and / or contaminating mixtures, such as wood and metal, or other undesirable materials.

In embodiments, virgin material may include particle sizes in the range of 0 to 63 mm. As is known in the art, particle size ranges may be expressed as dD or alternatively as d / D. Generally, sizing ranges are expressed as d / D, where d is the minimum value through which a particle can pass and D is the maximum square mesh grating. The particle size range of 0-63 mm can also be written as 0 / 63, for example.In the embodiment, the virgin material may contain particle sizes of 0 / 22, 0 / 45, or 0 / 63.

[0013] The second material may be recycled material. Recycled material may be material already used, for example, as building material. Recycled material may include artificial stone, and / or fragments of artificial stone and / or concrete. Recycled material may be limited to artificial stone, and / or fragments of artificial stone and / or concrete.

Artificial stone is sometimes called artificial rock. The recycled material may be recycled aggregate and / or recycled artificial stone, i.e., construction waste or demolition scrap such as concrete and / or crushed concrete. The second material may not contain or include household waste and / or domestic waste. The second material may not contain incineration slag of household waste and / or domestic waste. The recycled material does not contain or include household waste or incineration slag of household waste. As is known in the art, domestic waste may be any waste generated in the household environment.

[0014] The second material may also be and / or comprise masonry, crushed masonry, such as bricks, tiles, or artificial stone, or mixtures thereof. The second material may contain particle sizes smaller than at least one of 4 mm, 2 mm, or 1 mm. The particle sizes may range from 0 to 200 mm. In embodiments, the recycled material may contain particle sizes of 0 / 22, 0 / 45, or 0 / 63.

[0015] The first material may be washed together with the second material in at least one washer. At least one washer may be a washer in a processing plant. The first material may be washed together with the second material in at least one washer in a processing plant. The first and second materials may be mixed before or during washing. The first and second materials may be washed as a mixture or as a mutual mass flow in at least one washer. The entire particle size fraction of the first and second materials may be washed in at least one washer, or only particle size fractions of 0 / 2 mm, 0 / 3 mm, or 0 / 4 mm may be washed in at least one washer.

[0016] At least one washer can remove and leach components such as clay and loam, as well as contaminating mixtures such as wood and metal. Herein, leachable materials may be defined as materials that can be separated or removed by washing. These components may be described as washable components. Washable components may be components that can and / or are leached. Washable components may be components that can be separated and / or removed by washing. Washable components may be solids or particles in a mixture that can be removed through a leaching process. In this process, particles and / or components are separated and washed away by rinsing or washing to separate them from the rest of the mixture. The first and second materials may include finely distributed clay-like substances and / or fine aggregate powders, which may exist in lumps in the aggregate or adhering to particles. These components may also be described as washable components. These components, when present in large quantities, can adversely affect concrete. Therefore, removing washable components is important for the quality of building aggregates. This has the advantage that the washable components of both the first and second materials are removed together, potentially resulting in a homogeneous material with uniform material properties. These properties are also important for the quality of building aggregates. Washing the first material together with the second material in at least one washer can also improve the quality and usefulness of the material, ensuring that the material meets the desired quality standards for further processing or final use. Furthermore, there is no need to remove materials other than the washable components, and there is no need to supply additional virgin material. Thus, resource depletion, habitat destruction, and energy consumption are minimized, making the process more environmentally friendly and sustainable without sacrificing product quality.

[0017] A predetermined mass ratio of the masses of the first material and the second material can be established before or during the supply of the first material and the second material to the processing plant.

[0018] A predetermined mass ratio of the masses of the first and second materials can be established before or during the supply of the first and second materials to the processing plant. The mass ratio can be established in wt% (weight%) or vol% (volume%). The mass ratio of the first and / or second materials can be adjusted and / or controlled. The mass ratio can be adjusted by supplying the first and second materials at different ratios and / or supply rates. Thus, the mass ratio can be adjusted dynamically according to a predetermined purpose. The mass ratio may also be measured by at least one mass measuring means, which may be a weighting machine or weighting device. Furthermore, the weight can be estimated by the volume of the first or second material, for example, the volume carried by a wheel loader or material stacking. For example, if a wheel loader stacks eight shovels of the first material and two shovels of the second material onto a pile, the pile may contain 20% of the second material. Defining mass ratios in advance has the advantage of allowing product quality to be defined at an early stage, and / or allowing the material properties and / or composition to be adapted to the intended use and / or purpose.

[0019] The mass ratio of the first material and / or the second material can be adjusted so that the mutual mass flow of both materials includes any proportion of the second material, such as 1-5%, 5-10%, 10-15%, 15-20%, or 20-99%. Any proportion of 20-99% may include 20-25%, 25-30%, 30-35%, 35-40%, 40-45%, 45-50%, 50-55%, 55-60%, 60-65%, 65-70%, 70-75%, 75-80%, 80-85%, 85-90%, 90-95%, or 95-99%. By adjusting the mutual mass flow, the properties and / or qualities of the materials can be adjusted according to the intended purpose.

[0020] The mass of the materials can be determined by the volume and / or weight of each material. Washing the first and second materials in a given mass ratio has the advantage that the washable components of both materials are removed. Thus, the washable components of the first and second materials can be removed together in the same method step. Thus, the first and second materials can form a homogeneous material. In the embodiment, only fractions of 0 / 2 mm, 0 / 3 mm, or 0 / 4 mm can be washed by at least one washer. Thus, the sand and / or sand-grain mixture of the second material does not need to be removed and / or filled in. Furthermore, since it is not necessary to remove the sand and / or sand-grain mixture of the second material, there is no need to add virgin material. This has the advantage that the washable components of fractions of 0 / 2 mm, 0 / 3 mm, or 0 / 4 mm of the first and second materials are removed together, resulting in a homogeneous sand and / or sand-grain mixture. The washable components may have a particle size <0.0063 mm. Sand and / or sand-grain mixtures can possess the properties of virgin sand and / or sand-grain mixtures and may not need to be declared as recycled material. Recycled sand and / or sand-grain mixtures do not need to be removed and landfilled, but can be used as building aggregate. Therefore, there is no need to remove the second material sand and / or sand-grain mixture, and thus there is no need to add virgin material. This minimizes the use of virgin material, and therefore resource depletion, habitat destruction, and energy consumption. Thus, this process is cost-effective, efficient, energy-efficient, environmentally friendly, and sustainable while supplying high-quality products.

[0021] The first material and the second material can be sized together by at least one sizer. The first material and the second material can be mixed before or during sizing. The first material and the second material can be mixed by at least one sizer. At least one sizer may be a sorting system that includes a dry sorting system or a wet sorting system. The first material and the second material can be sized before, during, and / or after washing with a washer. In embodiments, the first material and the second material can be sized before washing the material in the washer. At least one sizer may have at least two screens. At least one screen may be a sieve. The material to be sized may be placed on a screen that is rotated or shaken. The sizer may be a plan shifter, a tumbler sorter, or a grinder equipped with a vibrating sorter. The first material and the second material can be sized as a mutual mass flow by at least one sizer. The sizer may include a washer.

[0022] Sizing the first and second materials together has the advantage of making the materials more homogeneous and / or easier to process. It also has the further advantage of eliminating the need for separate machines and thus minimizing energy consumption.

[0023] The first and second materials may be sized by at least one sizer before washing in a washer. The first sizer can remove oversized particles from the first and second materials. Oversized particles are a term used for residues that have a particle size too large for the sorting machine used in the sizer. The oversized particles may be fed into a crusher to crush the particles to a predetermined particle size range. The crusher may be a hammer crusher, a cone crusher, a swirling crusher, a roller crusher, an impact crusher, or any other crusher known in the art.

[0024] In this embodiment, the first sizer can separate sand or a mixture of fine-grained sand and gravel (e.g., 0 / 2 mm, 0 / 3 mm, or 0 / 4 mm) from gravel (e.g., 2 / 32 mm, 3 / 32 mm, or 4 / 32 mm).

[0025] In the embodiment, a mixture of the first and second materials may be sized by a second sizer. In this step, the sizer or sorter produces concrete-specific particle sizes (e.g., 0 / 2 mm, 0 / 3 mm, 0 / 4 mm, 2 / 4 mm, 4 / 8 mm, 8 / 16 mm, and / or 16 / 32 mm). The product may be administered by a speed-controlled dosing belt with a belt weight and optional computer-assisted dosing software.

[0026] At least one sizer may be a wet sorting system or wet sizer, or a dry sorting system or dry sizer. The first and second materials may be washed during sizing by the wet sorting system. Thus, the sizer may include washers. The wet sorting system may include a first washer. The terms sorting system and sizer may be used interchangeably. The sizer may have at least two decks. Each deck may have a screen for sizing the material. In embodiments, the sizer may have at least three decks. The sizer may have a first deck with a first screen, a second deck with a second screen, and a third deck with a third screen. Furthermore, the sizer may have a drain. The first screen may have the largest mesh size and be able to remove the largest particle size fraction. The first screen may have a mesh size of 16 to 32 mm. Particle size fractions smaller than the mesh size of the first screen can pass through the first screen and be sized by the second screen. The mesh size of the second screen may be smaller than the mesh size of the first screen and larger than the mesh size of the third screen. The first screen can have a mesh size of 8 to 16 mm. Particle size fractions smaller than the mesh size of the second screen can pass through the first screen and be sized by the third screen. The third screen may have the smallest mesh size. The first screen can have a mesh size of 2 to 8 mm, 3 / 8 mm, or 4 / 8 mm. Particle size fractions that pass through the third screen (i.e., 0 to 2 mm, 0 to 3 mm, or 0 to 4 mm) can be removed by a drain. In the case of a wet sizer, each deck may include multiple nozzles. Nozzles may be positioned above the corresponding screen and above the material being sized. Nozzles can wet the screen and / or the material. Nozzles can spray the screen and / or the material, i.e., water can be used.By wetting the screen and / or the material, the material can be washed, the quality of the material can be improved, and washable components can be removed. The minimum particle size may be 0 - 2 mm, 0 - 3 mm, and / or 0 - 4 mm, and can be discharged through a drain together with water. In an embodiment, the minimum particle size (e.g., 0 - 2 mm, 0 - 3 mm, or 0 - 4 mm) can be further washed in a second washer, and washable components can be removed. If the sizer is a dry sorting system, the sizer may not include a washer, and the minimum particle size (e.g., 0 - 2 mm, 0 - 3 mm, or 0 - 4 mm) can be washed in a second washer, and washable components can be removed. In this embodiment, the second washer can be the first washer.

[0027] In an embodiment, the particle size fraction 0 / 2 mm, 0.3 mm, or 0 / 4 mm can be sized by a third sizer. The third sizer can be an upflow classifier. The third sizer can use a gas or liquid flow that flows in a direction opposite to the sedimentation direction. The third sizer can be a hydrocyclone. The hydrocyclone can separate particle size fractions <0.063 or <0.02 mm from the material. <0,000085>

[0028] The first material and the second material can be discharged from the processing plant.

[0029] Then, the first material and the second material can be classified into different particle size fractions and discharged from the processing plant. <,

[0030] Construction aggregates and / or particle size fractions of construction aggregates can be discharged from the processing plant by at least one processing plant discharge. The processing plant can have a plurality of discharges. The number of discharges can correspond to the particle size fractions sized by at least one sizer.

[0031] The first material and / or the second material can be conveyed by a conveyor. The conveyor can have at least one conveyor section. The at least one conveyor section can include at least one conveying means having at least one conveying direction and at least one conveying speed, and it can further include at least one of a mass measuring means, a conveyor supply section, and a conveyor discharge section. The at least one conveying means can supply the first material and / or the second material to a processing plant. The first material and / or the second material can be supplied to at least one conveyor supply section of the at least one conveying means.

[0032] The at least one conveying direction can be from at least one conveyor supply section to at least one conveyor discharge section. The first material and / or the second material can be conveyed in the at least one conveying direction. The first material and / or the second material can be discharged at the at least one conveyor discharge section. The at least one conveying means can be a belt conveyor such as a modular belt conveyor, a cleated belt conveyor, an inclined / declined belt conveyor, a lifting conveyor belt, a wheel loader, a conveyor pipe, a belt feeder and / or a conveyor line. The at least one supply section can be a supply hopper, a supply hopper for recycling materials, a chute, and / or the at least one conveying means itself. The at least one measuring means can be a measuring instrument such as a weighing belt weigher, a control supply belt weigher, a conveyor scale, a radiation belt weigher, a belt scale and / or a belt weigher.

[0033] The conveyor can have a first conveyor section and a second conveyor section. The first conveyor section can include a first conveying means having a first conveying direction and a first conveying speed, and it can further include a first mass measuring means, a first conveyor supply section, and a first conveyor discharge section. The first conveying direction can be from the first conveyor supply section to the first conveyor discharge section.

[0034] The second conveying unit may include a second conveying means having a second conveying direction and a second conveying speed, which may further include a second mass measuring means, a second conveyor supply unit, and a second conveyor discharge unit. The second conveying direction may be from the second conveyor supply unit to the second conveyor discharge unit.

[0035] The measuring means has the advantage of being able to measure and / or adjust the mass ratio and / or mass flow while each material is being transported. Therefore, the quality of the material can be adjusted and / or the material's properties and / or composition can be adapted to the intended application and / or purpose.

[0036] The first and / or second transport speeds may be variable.

[0037] The first material may be conveyed along a first conveying direction. The second material may be conveyed along the first conveying direction and / or a second conveying direction.

[0038] The first material may be transported by a first transport means, and the second material may be transported by a second transport means before supplying the first and second materials to the processing plant.

[0039] The first conveyor supply unit may be connected to the first transport means, and / or the second conveyor supply unit may be connected to the second transport means. The first material may be transported by the first transport means, and / or the second material may be transported by the second transport means to supply the first material and / or the second material to the processing plant. The first material may be supplied to the first conveyor supply unit (first conveyor supply unit) of the first transport means, and / or the second material may be supplied to the second supply unit (second conveyor supply unit) of the second transport means. The first mass measuring means may be connected to the first transport means, and the second mass measuring means may be connected to the second transport means.

[0040] The first and second conveying means may form an angle α. The angle α may be 0 to 90°. In embodiments, the angle α may be 0° to 5° or 85° to 90°. An angle α of 0° to 5° or 85° to 90° has the advantage that the material can be supplied more accurately without the material unnecessarily losing each conveying means. Depending on the mass flow, the amount of material lacking each conveying means can add up to a large number, reducing efficiency, causing problems with functionality, and potentially complicating the adjustment and / or adaptation of the material's quality and / or properties and / or composition.

[0041] The mass ratio of the first material to the second material can be established by supplying the first material to the first conveying means and the second material to the second conveying means.

[0042] The mass flow of the first material may be measured by a first measuring means, and / or the mass flow of the second material may be measured by a second measuring means.

[0043] The second material may be discharged to the conveying means together with the first material. The second material may be discharged to the first material and / or the first conveying means. The first material and the second material may form a reciprocal mass flow and / or mixture of the first material and the second material in the first conveying means. The reciprocal mass flow of the first material and the second material may be formed by discharging the second material to the first conveying means or by discharging the first material to the second conveying means. The first material and the second material may be conveyed to the first conveying means as a reciprocal mass flow and / or mixture of the first material and the second material. The second material may be discharged by a second conveyor discharge section. The second material may be discharged by a second conveying means at the second conveyor discharge section. The second conveyor discharge section may be located adjacent to or above the first conveying means. This has the advantage that the mixing of materials is already carried out in the initial stages and a reciprocal mass flow is established. Furthermore, it is advantageous that the first and second materials can be introduced into the processing plant simultaneously, thereby making the process more efficient.

[0044] The mass ratio of the first material to the second material can be adjusted by adjusting the conveying speed of the first conveying means (first conveying speed) and / or the conveying speed of the second conveying means (second conveying speed). The first conveying speed and / or the second conveying speed can be adjusted manually and / or by a controller. The first conveying speed and / or the second conveying speed can be adjusted and / or controlled according to the mass flow of the first material and / or the second material as measured by the first measuring means and / or the second measuring means. The first conveying speed and the second conveying speed can be independently variable. The mass ratio of the first material and / or the second material can be adjusted so that the mutual mass flow of both materials includes any percentage of the second material, such as 1-5%, 5-10%, 10-15%, 15-20%, or 20-99%. While the mass flow of the second material can be adjusted, the mass flow of the first material may remain unchanged. While the mass flow of the first material may be adjusted, the mass flow of the second material may remain unchanged. In this embodiment, the mass flow of the first material may be a continuous mass flow, while the mass flow of the second material may be adjustable. By adjusting the respective conveying speeds, the quality and / or characteristics and / or composition of the product can be more easily adjusted and / or controlled. This can improve the quality of the final product.

[0045] If the proportion of the second material is too low (e.g., <20%, <15%, or <10%) in the reciprocal mass flow and / or the mixed first and second materials, the conveying speed of the second conveying means (second conveying speed) can be increased and / or the conveying speed of the first conveying means (first conveying speed) can be decreased. If the reciprocal mass flow and / or the mixture of the first and second materials contains too high a proportion of the second material (e.g., >20%, >15%, or >10%), the conveying speed of the second conveying means (second conveying speed) can be decreased and / or the conveying speed of the first conveying means (first conveying speed) can be increased. Alternatively or additionally, the conveying speed of the first conveying means can be increased or decreased accordingly.

[0046] The first material and the second material can be discharged to the processing plant by the first conveyor discharge section. The first conveyor discharge section can discharge and / or supply the mutual mass flow of the first and second materials, and / or a mixture of the first and second materials, to the processing plant. The mutual mass flow of the first and second materials, and / or a mixture of the first and second materials, can be supplied to the processing plant. The mutual mass flow of the first and second materials, and / or a mixture of the first and second materials, can be supplied together to the processing plant. This has the advantage that the materials are already mixed, resulting in improved mixing when introduced into the processing plant. It is even more advantageous because the materials are introduced into the processing plant simultaneously, making the process more efficient and energy-efficient.

[0047] An apparatus for manufacturing building aggregates may include a conveyor having a first conveyor section for a first material and / or a second conveyor section for a second material. The first material may be virgin material. The second material may be recycled material.

[0048] The apparatus for manufacturing building aggregates may further include a processing plant for virgin and recycled materials, and a feed section and washers for the processing plant. The first conveying means may be connected to a virgin material source, and the second conveying means may be connected to a recycled material source. The virgin material source and / or recycled material source may be a deposit of virgin or recycled material, a bunker, a silo, or a hopper.

[0049] An apparatus for manufacturing building aggregates may include a conveyor having at least two conveyor sections. The first conveyor section may include a first conveying means having a first conveying direction and a first conveying speed, which may further include a first mass measuring means and / or a first supply section and / or a first conveyor discharge section. The second conveyor section may include a second conveying means having a second conveying direction and a second conveying speed, which may further include a second mass measuring means and / or a second supply section and / or a second conveyor discharge section. The first supply section may be connected to the first conveying means, and / or the second supply section may be connected to the second conveying means. The first mass measuring means may be connected to the first conveying means, and / or the second mass measuring means may be connected to the second conveying means.
