The Operating Principle Of The Ball Mill
the operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed mar 17, 2017 how a conical ball mill operates & what is its working principle. hardinge mills may be used for grinding limestone or raw material mixtures used in the manufacture of portland cement, cement clinker and coal, either as preliminary or finishing machines, or as units to complete the grinding in one operation.figure ball mill grinding circuit the ball mill is in closed circuit with a sump and three cyclone classifiers. the ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. the slurry from the ball mill is pumped out of a sump into two cyclone separators. the underflow may 13, 2020 race and ball mill. simple arrangement of race and ball mill is shown in the figure. It consists of upper and lower races and filled with steel balls in between them. the raw coal from the feeders passes between the rotating races again and again until it has been pulverised to the desired degree of fineness.
