Technical Field

[0001] The utility model relates to the technical field related to roller mills, in particular to a crushing high-pressure roller mill for producing coal gangue sintered insulation bricks. Background Art

[0002] Sintered porous bricks are made of clay, shale, coal gangue, fly ash, silt (river and lake silt) and other solid waste as the main raw materials. They are made by roasting and have a porosity of no more than 35%. The holes are small in size and large in number. They are mainly used in load-bearing parts. The raw materials need to be crushed before processing. In order to ensure the processing rate, a high-pressure roller mill is generally used to crush the raw materials.
