Grinding in Ball Mills: Modeling and Process Control

There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].

What Are the Differences between Dry and Wet Type Ball Mill?

The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

Grinding Media Sizing – Metcom

Ball mill grinding efficiency is directly influenced by the size distribution of the grinding balls in the mill. Determining the ball size (or sizes) that should be added to a plant ball mill to obtain optimal performance requires consideration of a number of factors including: circuit feed size distribution, target grind size, and ore breakage characteristics.
