Environment-friendly treatment and recycling method for metallurgical waste residues

Abstract

The invention discloses an environment-friendly treatment and recycling method for metallurgical waste residues. A crushing and grinding device is adopted in the environment-friendly treatment and recycling method for the metallurgical waste residues, and comprises a working box, a first-stage crushing mechanism, a second-stage crushing mechanism, a grinding mechanism and a material leaking plate.The problems that in the traditional metallurgical waste residue recycling and treatment process, a traditional machining mode cannot conduct crushing and grinding integrated machining treatment on metallurgical waste residues, grinding machining needs to be conducted after the metallurgical waste residues are crushed in a unified mode, the metallurgical waste residue treatment efficiency is affected accordingly, besides, sieve holes are easily blocked by ground particles in the traditional grinding machining process, consequently, smooth grinding operation is affected, metallurgical waste residues are crushed singly in a traditional crushing mode, the particle size of the crushed waste residues cannot be guaranteed, and subsequent grinding operation is affected are solved.

Description

technical field [0001] The invention relates to the technical field of recycling metallurgical waste residues, in particular to an environmentally friendly treatment and reuse method for metallurgical waste residues. Background technique [0002] Metallurgical waste refers to various solid wastes produced in the production process of the metallurgical industry, especially blast furnace slag produced in the process of metallurgical operations, which belongs to silicate materials. It has stable chemical properties, and has the characteristics of anti-wear and water absorption. It can be used to make raw materials for different needs. It is common to use slag as a raw material for making cement, concrete, and ceramic products after recycling and processing. For blast furnace slag In the recycling process, it needs to go through multiple processes such as crushing, grinding, and iron removal before it can be reused. [0003] However, in the process of recovery and utilization o...

Problems solved by technology

[0003] However, in the process of recovery and utilization of traditional metallurgical waste slag, the traditional processing method cannot carry out integrated processing of crushing and grinding of metallurgical waste slag, and it is necessary to carry out grinding processing after uniform crushing of metallurgical waste slag, which affects the efficiency of metallurgical waste slag treatment. During the grinding process, the ground particles are easy to block the sieve hole, which affects the smooth progress of the grinding operation, and the traditional crushing method only crushes the metallurgical waste slag, and the particle size of the waste slag after crushing cannot be guaranteed, which affects the subsequent grinding operation
