Limestone processing system

Abstract

The invention belongs to the technical field of limestone processing, and discloses a limestone processing system. The limestone processing system comprises a primary processing crushing unit, a finish processing crushing unit, a sand stone separating unit and a lime production unit. According to the limestone processing system, a limestone raw material is screened, crushed, and screened again through the primary processing crushing unit, soil in the limestone raw material can be effectively removed, clean stone materials with large particle diameters are obtained and sent to the finish processing crushing unit to be fine-crushed, then separation is conducted through the sand stone separating unit, finally high quality sand stone materials for concrete can be obtained, and the quality of the concrete prepared by using the system is effectively guaranteed. Meanwhile, collected stone powder is sent to a lime sintering furnace to be sintered to lime through the limestone processing system, environmental pollution is avoided, sintering time of the limestone can be shortened, resources are saved, meanwhile water is not needed by powder generating through the sintered lime, powder can begenerated by slightly crushing, and water resources are saved.

Description

technical field [0001] The invention belongs to the technical field of stone processing, and in particular relates to a limestone processing system. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is composed of cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, densely formed, cured and hardened. artificial stone. [0003] Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an im...

AI Technical Summary

Problems solved by technology

[0004] Since the raw materials for making concrete are either powder or granular, there is a certain degree of pollution or destructiveness in both production and transportation. For example, dust will be formed in the production process of powdery raw materials (cement), and the production process It will destroy mountains, destroy vegetation, etc. As the country pays more and more attention to environmental pollution and continuously introduces environmental protection policies, the raw materials of concrete gradually form a seller's market, resulting in the quality of concrete raw materials currently on the market. The stone contains a lot of soil, and the washed sand is not clean, which poses a serious hidden danger to the quality of concrete
