Process reform practice of slime water system in Liyazhuang Coal Preparation Plant
Aiming at the main problems in the slime water system of Liyazhuang Coal preparation plant,such as high ash content and low ash content of coarse and fine slime,this paper makes full use of the existing process system equipment of the coal preparation plant,and puts forward the process transformation scheme of replacing the multi-layer fine screenwith stacked high frequency screen,separating the magnetic tail of the waste and secondary flotation of slime.After the transformation,the clean coal yield is increased by 1.18%.The coal slime ash content is increased to more than 70%,and the annual economic benefit is increased by 6.348 million yuan,and also obtains better transformation effect.
