At present, most domestic difficulty selects coarse slime still to pass through liquid-solid fluid bed separation, but practice shows, the liquid-solid fluid bed process difficulty of tradition selects coarse slime effect poor, when requiring sorting under cleans ash condition, clean coal yield is extremely low, improves clean coal yield, cleans ash exceeds standard seriously, has had a strong impact on production and the economic benefit of enterprise.
Select the Apparatus and method for of coarse slime height sorting seriously to constrain the development of coal preparation technique for difficulty, become the bottleneck problem that coal preparation plant ensures product quality, increases economic efficiency gradually.Only have and solve the difficult effective sorting problem selecting coarse slime processing links, the pollution to cleaned coal could be reduced, ensure the maximization of wholegrain level quality of cleaned coal and productive rate.
