Problems solved by technology

[0004] Existing building material manufacturers, in order to deal with these stone slab wastes, most of them are disposed of in the open or buried. The huge burden has caused several manufacturers to be at a loss for the waste of stone slabs they will produce in the future, and they are in the embarrassment of not knowing what to do. Some unscrupulous manufacturers even discard them at will, damaging the environment

Embodiment Construction

[0036] see figure 1 As shown, the present invention relates to a method for recycling and reusing stone slab waste, which is the "primary waste" formed by the remaining stone slab waste after cutting by the stone factory or the originally flawed stone slab waste, etc. The stone slabs obtained after cutting are placed in a mold, and the "secondary waste" that cannot be reused after cutting is crushed, mixed with an appropriate amount of cement, water and sand to form concrete, and the Concrete is poured into the mold covered with stone slabs. After hardening, the mold can be removed to obtain a large-area building material whose surface is composed of several stone slabs. In the above method, the present invention can fully utilize the recycled stone slabs , there is no cost to obtain raw materials, and the formed waste materials are all crushed to form fine gravel and then reused. In the manufacturing process, the amount of sand and gravel used can be reduced. In addition to g...

Abstract

The invention discloses a method for recycling and reusing stone slab waste. The method comprises the steps of recycling primary waste formed by the remaining stone slab waste after cutting or the originally-flawed stone slab waste from a stone factory, screening the primary waste, sending the waste without meeting recyclability requirements to a grinder for grinding, cutting the screened recyclable primary stone slab waste to strip-shaped stone slabs or small-area stone slabs, sending all remaining cut secondary waste which can not be cut for use anymore to the grinder for grinding, mixing the ground stone slab waste with a moderate amount of cement, water and sands to form concrete; laying the cut stone slabs on the bottom of a mould; filling the concrete in the mould in which the stone slabs are laid; carrying out hardening; and dismantling the mould and then obtaining a finished product. The method has no cost for obtaining raw materials due to complete utilization of the recycled stone slabs, the manufacturing cost is reduced since all the formed waste is utilized after the waste forms fine particles, and no waste is generated anymore in the whole method.

Description

technical field [0001] The invention relates to a method for recycling waste stone slabs, in particular to a method for completely reusing waste stone slabs to regenerate building materials without generating any waste. Background technique [0002] Due to the special texture on the surface of natural stone, it is deeply loved by consumers, and building materials made of natural stone have been widely and widely used in recent years. [0003] In the production of stone slabs, the original stone is cut and polished. Since natural stone also presents a natural and unspecified outline after cutting, not all of the cut stone slabs can be made into finished products during the production process. Unavoidably, some of them must be due to the irregular edges of the original stone. The required specifications cannot be formed, resulting in waste, or some of them are flawed or broken during the production process, forming defective products. These waste and defective products must b...
