WhatsApp: +86 18838072829Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

WhatsApp: +86 18838072829A ball mill operates by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation of the cylinder is typically between 4 to 20 revolutions per minute, depending on the diameter of the mill. The larger the diameter, the slower the rotation.
