Embodiment 1
[0054] The tunnel kiln production line process equipment of a shale brick factory is used to process electrolytic manganese slag to produce ecologically active slag and ecologically active slag powder:
[0055] (1) Batching and homogenization: stone coal (calorific value 1210kcal / kg), muddy waste rock chips, and partially agglomerated electrolytic manganese slag that has been stored and aged are all crushed to a particle size of <35mm, in parts by weight, 50 parts of electrolytic manganese slag, 15 parts of stone coal, 34.5 parts of mud-containing waste rock chips and 0.5 parts of ZC-S1 alteration agent are batched by computer, and continuously sent to the Raymond mill system, and mixed and ground to make a sieve quality of 80 μm 26% powder, then add 11 parts of water, mix and homogenize into a plastic material;
[0056] (2) Forming: The plastic material obtained in step (1) is formed into a porous brick-like material by a brick-making machine, and dried naturally;
[0057] (...
Embodiment 2
[0065] The tunnel kiln production line process equipment of a refractory brick factory is used to process electrolytic manganese slag to produce ecologically active slag and ecologically active slag powder:
[0066] (1) Batching and homogenization: crush stone coal (calorific value 1530kcal / kg) and dry-process acetylene carbide slag to a particle size <35mm, and mix 71 parts by weight of granular electrolytic manganese slag (particle size <10mm ), 8.5 parts of stone coal, 20 parts of dry-process acetylene carbide slag and 0.5 part of ZC-S1 alteration agent are mixed by computer, and are continuously sent to the Raymond mill system, and mixed and ground to make 80 μm sieve quality of 18% powder material, then add 13 parts of water, and homogenize into a plastic material through mixing;
[0067] (2) Forming: The plastic material obtained in step (1) is formed into a brick-shaped material by a brick forming machine, and dried naturally;
[0068] (3) Tunnel kiln calcination: send...
Embodiment 3
[0075] The tunnel kiln production line process equipment of a refractory brick factory is used to process electrolytic manganese slag to produce ecologically active slag and ecologically active slag powder:
[0076] (1) Batching and homogenization: crush the agglomerated wet-process acetylene carbide slag to a particle size <35mm, and mix 18 parts of ridged dewatered municipal sludge (calorific value 1875kcal / kg), 21.5 parts of wet Acetylene carbide slag and 0.5 parts of ZC-S7 alteration agent are used for the first-stage computer batching, and mixed and ground to make a powder with 80 μm sieve quality of 25%, and then the obtained powder is mixed with 60 parts of water-containing primary electrolytic manganese The slag (moisture content 30.8wt%, particle size <1mm) is batched by the second-stage computer, and sent to the rolling device to be homogenized into plastic materials;
[0077] (2) Forming: The plastic material obtained in step (1) is formed into a brick-shaped materi...
