Finish Grinding System. The common cement grinding systems are summarized in Figure 1 and can be divided up into three main groups: Ball Mill. All grinding work is done in the ball mill and the set-up is: Ball mill in open circuit; Ball mill in closed circuit with; Mechanical air separator; Rotor type separator; Ball Mill with Pregrinding Unit

Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12).

11-01-2017· A grinding wheel with a rougher grit will remove more material per pass, but the result is a rougher surface finish. A finer grit will remove less material per pass, but give you a smoother finish. The drawback to a finer grit is the potential for clogging of the wheel and over heating of the plastic which results in burnishing or burning of the surface.
