► Ball mills are a grinders for reducing hard materials to powder.
► A ball mill grinds material by rotating a cylinder with balls causing the balls to fall back into the cylinder and onto the material to be ground.
► The cylinder rotates at a relatively slow speed, allowing the balls to cascade through the mill base, thus grinding or dispersing the materials.
► Ball mills are generally used to grind material 7mm and finer, down to the particle size of 20 to 75 microns.
