In Grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize just in case. Well, this safety factor can cost you much in recovery andor mill liner wear and ...
Oct 19, 2015 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-Chalmers
Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters Morrell, 1996. Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications.

Nov 18, 2008 We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.
Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary ...
