Jul 03, 2017  Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft..

Ball Mill vs Rod Mill How To Choose Ball Mill or Rod ...

The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% – 1%; the loading capacity of rod is about 35% – 45% of the effective volume ...

Jan 01, 2016  In recent times, these mills have successfully replaced the conventional rod mill–ball mill configurations. In Australia, the number of AG/SAG mills increased from about six in 1984 to more than 40 in the following 5-year period . The number of installations worldwide by mid 1989 was about 471, and presently the number is growing.

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
