Factory-type environment-friendly intelligent high-efficiency stone-crushing sand-manufacturing production process

Abstract

The invention relates to a factory-type environment-friendly intelligent high-efficiency stone-crushing sand-manufacturing production process. The process comprises the steps that large stone is crushed, medium stone is crushed, the sand is manufactured, and finished sand is subjected to continuous grading adjustment. Stone-crushing sand-manufacturing facilities of the whole production line are put in a factory, uncontrollable factors are put into in the controllable environment, the remarkable effect of safety, high efficiency, low energy consumption, zero sewage discharging and zero waste are achieved, and high-standard sand-stone materials needed by large-scale construction projects of the country are produced.

Description

technical field [0001] The invention belongs to the technical field of mine gravel sand making machinery, and relates to a factory-type environmentally friendly intelligent high-efficiency crushing machine. [0002] Stone sand production process. Background technique [0003] Since the reform and opening up, the mining machinery industry has little R&D investment, small enterprise scale, low technological content of products, one-sided pursuit of main engine output, and the main engine is getting bigger and bigger, with few breakthrough technologies, and still stays in the traditional mechanical mode. Specifically, the following problems exist: [0004] First, the crushed stone sand making machine still adopts the traditional mechanical principle and technology, resulting in the quality problems of powder and needle flakes exceeding the standard, sand powder separation, continuous grading and other quality problems in the finished sand produced by the sand and gravel produc...

AI Technical Summary

Problems solved by technology

[0005] Second, sand and gravel production enterprises adopt open-air production, and the dust generated by crushed stone sand making will pollute the air environment; at the same time, in order to reduce the powder content of the finished sand, the finished sand is generally washed with water, which also causes waste water to pollute the water environment

[0006] The third is that the crushing and sand making machinery still adopts the manual control mode, which has low production efficiency, high energy consumption, and many potential safety hazards

[0007] Fourth, washing finished sand not only wastes water resources, but also causes a large amount of powder to become mud and be discharged with sewage, wasting ore resources, which is not in line with the country's goal of developing a resource-saving society
