Production process of sintered building aggregate

Abstract

The invention discloses a production process of a sintered building aggregate. The production process comprises the following steps: preparing raw materials, grinding industrial waste residues, homogenizing and aging, granulating, preparing a fuel, calcining and sintering, cooling, screening and packaging. Various raw materials such as shale, coal cinder, clay and sludge are matched and sintered to generate minerals such as composite aluminate to form a high-strength compact building aggregate; the nearby material selection range of factory raw materials is wide; the industrial waste residuescan be digested and treated; in addition, in the material aging process, a stacker-reclaimer is used for homogenizing the mixed materials in a tiling and direct taking storage and taking mode; the preparation method is more beneficial to uniform components of the raw materials, ensures the quality stability of the product, directly presses the materials into a cylinder which is most suitable for binding reaction with cement in the concrete product to calcine, and is beneficial to enhancing the strength of the concrete by one-time finished products.

Description

technical field [0001] The invention relates to the technical field of building aggregate production, in particular to a production process of sintered building aggregate. Background technique [0002] Concrete is made of cement as the cementitious material, sand and gravel aggregate, and water through mixing, pouring, tamping and hardening. The sand and gravel aggregate accounts for 60%-80% of the concrete volume and is the most basic of engineering construction. The largest amount of raw material resources. Our country is rich in sand and gravel mineral resources, mainly in small mining sites, the phenomenon of excessive mining and random digging is serious, the quality of sand and gravel is uneven, and the concentration of aggregate enterprises is relatively low. Increased efforts, strengthened environmental protection, extensive mining is strictly restricted, the contradiction between market supply and demand is becoming increasingly prominent, and artificial building ag...

Problems solved by technology

[0003] Sintered aggregate is mainly for the large-scale development and utilization of resources, and the raw materials are determined by the resources in different regions. In the existing technology, mine resources are mostly used for preparation, which consumes a lot of raw materials, pollutes the environment, and is difficult to guarantee the quality of preparation. Therefore, it is reasonable Utilizing industrial waste to produce artificial building aggregates instead of natural resources to produce sand and gravel products is in line with the development of circular economy and reduces the mining of mine resources. It is an urgent need to improve the goal. Therefore, this invention proposes a production process for sintered building aggregates. Solve the problems existing in the existing technology
