| description | The invention belongs to the technical field of coal slime recovery of power coal preparation plants, and particularly relates to a non-quantitative washing method for low-quality coal slime. The method comprises a raw coal screening unit, a lump coal dry-method gangue discharging unit, a pea coal sorting unit, a slack coal dry-method deep screening unit, a slack coal sorting unit, a coarse slime recycling unit, a slime water treatment unit, a fine slime filter-pressing dehydration recycling unit and a filter-pressing slime crushing and mixing unit which are sequentially arranged along the washing process. According to the method, coal slime non-landing operation can be achieved, the links of forklift transfer, automobile transportation and the like are omitted, the environmental protection problem caused by coal slime sales is thoroughly solved, the effects of coal slime landing non-quantification, commercial coal yield maximization, water resource utilization saving and economic benefit noticing are achieve |
