design aspects of large ball mills

A ball mill is a hollow drum rotating around its horizontal axis

Ball mill design is rather simple. Drum Liners of ball mills operated on a large source material have ribs. A cylindrical ball mill used for grinding the coarse material. This mill should have a short length because the balls distributed uniformly over the entire length of the mill and during rotation obtained

SAG grinding) and Bond Ball mill work index, BWi (for ball mill grinding). A further measure, the Minnovex crusher index, Ci was also measured for use in the CEET program to determine SAG mill feed size (Kosick and Bennett, 2001). The SPI values varied from 13.5 to 107 minutes with an average of 53 minutes. This variability, although apparently

Ball Mill Application and Design

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼" to 1.5". The particles to be milled are trapped between the grinding media Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills.
