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

The invention discloses an environmental protection treatment and reuse method of metallurgical waste residue, which uses a crushing and grinding device, and the crushing and grinding device includes a working box, a primary crushing mechanism, a secondary crushing mechanism, a grinding mechanism and a material leakage plate; the invention overcomes the In the process of recovery and utilization of traditional metallurgical waste slag, traditional processing methods cannot carry out integrated processing of metallurgical waste slag by crushing and grinding. It is necessary to perform uniform crushing on metallurgical waste slag before grinding, 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 residue, and the particle size of the crushed waste residue cannot be guaranteed, which affects the subsequent grinding operation.
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...
