Then S and BM equations were determined from the size distributions at different grinding times and the model parameters S ai.a.y and fy were compared for five different mill speed fractional of mill critical speed 55 65 75 . 85 and 95 .
In this study, it was found that optimum grinding occurs at 85 of critical speed, compared to the optimum grinding at 70 of critical speed of the ball mill in the cement factory. The variation of a T values with the fraction of mill critical speed c gave high correlation coefficients of 0.98 and 0.96 for

A Ball Mill grinds material by rotating a cylinder with steel or ceramic grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed.However, most Ball Mills operate at speeds between 65 and 75 percent of critical speed.
However, most Ball Mills operate at speeds between 65 and 75 percent of critical speed. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.

Kim has presented batch grinding data for 1014 mesh size fraction of limestone ground in a 25.4 cm ball mill mill speed, N 0.50.8 5080 critical ball size, d 25.4 cm ball load, J 0.5 corresponding to 50 filling of mill volume by static ball charge particle load, U 1.0 corresponding to
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.

A cement mill or finish mill in North American usage is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The point where the mill becomes a centrifuge is called the Critical Speed, and ball mills usually operate at 65 to 75 of the critical speed. Application Ball mill is the key equipment for grinding after the crush process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory ...
