Technical field

The invention relates to the technical field of industrial waste slag and ore gravel processing equipment, specifically a sand and powder making device for dust-free and environmentally friendly analysis of slag.

Background technique

The processing of industrial gravel is a high-cost and low-yield processing technology at home and abroad. The production and operation costs of related equipment that can be directly used to process gravel into specific specifications are very high, and in the process of processing gravel, A large amount of dust will be produced, which will not only cause serious physical harm to the operator, but also cause serious pollution to the environment.

Relevant industrial slag and blast furnace smelting slag are generally rough-processed and crushed through jaw crushers and cone crushers for secondary use. However, the size and specification of the processed slag cannot meet the use of different projects and will affect the quality of the project; the hardness of the slag is also It cannot be screened, which affects the scope of use of the treated slag; the quality of the slag cannot be refined and screened, which seriously affects the recycling of the treated slag, and is not conducive to green production of factory processing.

In the smelting industry, the industrial preparation process will produce a large amount of burned industrial combustion waste residue. Through primary crushing, a large amount of waste residue will be directly abandoned. These waste materials are not easy to decompose and will have a very serious impact on the environment. The treatment of industrial waste residue at this stage Most of them are used as raw materials for roadbed laying through primary crushing, or are specially decomposed so that they can be processed into new building materials. However, the application effect in this area is not good. As a raw material for roadbed, it will cause danger due to the sharp edges of the slag. As a new type of construction raw material, the processing process is too cumbersome, the cost is high, and the practicability is low; therefore, technicians in related technical fields classify and crush the primary crushed slag into fine sand. This process has been widely used. However, at this stage, the equipment related to primary slag processing is a large-volume fully automatic processing device, and a large amount of dust will be generated during the slag processing, which will cause physical harm to the operator and serious environmental pollution.
