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.

The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.

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

SAG mills, or SemiAutogenous Grinding mills, use a combination of steel balls and rock particles to grind ore. They are larger in size and are capable of grinding larger quantities of ore than AG mills. SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size.
