Keep ReadingThe grinding process is briefly reviewed as follows. Firstly, coarse fresh ore O F is fed continuously into the ball mill by the conveyor. Meanwhile, a certain amount of mill water Q F is fed by means of a pipe to maintain the proper pulp density. The knocking and tumbling action of the steel balls within the mill crushes the coarse ore to a finer size.
