About coal water slurry rolling screen
Thread Content
In the preparation of coal-water slurry, what is the approximate proportion of large particles screened out by the rolling screen at the outlet of the rod mill? How do you deal with this part of the sieve?
The sifted material can be returned to the coal mill for recycling.
hope you can tell me: How many materials are usually discharged from the rolling screen of the coal mill in one shift (e.g. how many bucket trucks)? How to recycle or dispose of it?
The separated large particles are returned for regrinding. The question of the amount of returned material is not easy to answer. It is related to many factors such as the characteristics of the coal type, the amount of feed, the capacity and efficiency of the rod mill, etc.
