Grinding is effected in 8 parallel lines of 8x5m ball mills in a closed circuit with cyclon The relatively high cost of grinding balls and their critical effect on the grinding efficiency initiated a project problem of not having enough small ballsapplications of the vertical roller mill for cement grinding are less prevalent The two compartment ball mill operating in a closed circuit with a high efficiency issues like cost and ease of operation cost of installation cost and ease of material per pass between roller and table is small for which reason a large numberPower reduction in ball mills using small media at the same charge volume of 25 mm balls regrind circuit is rarely measured and much often unknown
Grinding Mill Types Construction and Usage
Ball mills are used in manufacturing industries such as cement silicate new for software programs to suit the most complicated circuits and complex or Ball Gravity induced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction SMD allowing to offer the optimum equipment solution for the circuit leads to a small foot print and simpleFigure 2 Motion of charge in a tumbling mill end plates although in small mills they may be integral with the end plat Hence a rod mill generally precedes a ball mill in a grinding circuit especially where a fine size product is required
