The theoretical suitable speed of the mill is 76 of the critical speed. The actual mills fluctuated around 76. In the current production when the rotation speed of the ball mill is less than 76 of the critical rotation speed it is called low-speed grinding when the rotation speed is higher than the critical rotation speed of 88 it is called high-speed grinding Speed grinding.

A Ball Mill grinds material by rotating a cylinder with steel grinding balls causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute depending upon the diameter of the mill. The larger the diameter the slower the rotation.

Apr 28 2017 First Stage of Ball Milling. Feed rate 15.31 T. per hr. Classifier Dorr duplex with baffled overflow. Ball load 28000 lb. of 3- and 2-in. balls. Speed 23.8 r.p.m. Ball-mill power 108 kw. Second Stage of Ball Milling. Feed rate 6.54 T. per hr. Classifier Dorr duplex. Ball load 28000 lb. of 2- and 1-in. balls. Speed 23.8 r.p.m.

was determined by deducting the installed ball mill pinion power of 7.95 kWht from the maximum overall circuit power of 16.7 kWht to give 8.75 kWht. Overall power for the comminution circuit SAG plus ball mills base on a maximum ball mill Wi of 19.1kWht ave. 18.1kWht plus one standard

May 10 2019 By the way the larger the diameter of the ball mill the lower the filling rate. For the rod mill the filling rate is generally 10 lower than that of the ball mill of the same specification. 2.2 Diameter of steel grinding ball. The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore.
