SAG vs. AG Mills: Understanding the Key Differences ball mills supplier

SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size. SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media.

The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.

Ball mill Wikipedia

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
