#### Ball Mill Motor Power Draw Sizing and Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-ChalmersPROCESS DIAGNOSTIC STUDIES FOR CEMENT MILL ,The mill load level is calculated by using factors and comparing various signals, including the total fresh feed, the recirculating flow rate, the mill sound, and the discharge bucket elevator power as well as the mill motor power. The factors that are taken into account for determination of the mill load level are shown in Annexure I.

#### Particle size reduction, screening and size analysis

Hammer, ball and rod mills frequently have screens on their discharge to retain large particles and media while passing fine particles. Other separation techniques include froth flotation, in which the difference in surface chemistry between a desired material and waste is exploited to float fine particles attached to air bubbles.Ballnose Cut Depth Musings for Feeds and Speeds in G,Simply put, the cutting edges get less access to coolant and air for cooling and it is harder for them to drag the chips up and out of the way. Hence we penalize surface speedand chip load. Here again, the definition makes sense given that we’re making chips all along the full distance (radius of the ball).
