Once you know the ideal speed of rotation for your mill jars, you will need to design your mill around this critical parameter. With most ball mill designs, you have two areas of speed reduction to tweak: from the motor drive shaft to the drive pulley and from the roller bar to the milling jar.

New and Used Ball Mills for Sale Savona Equipment is a new and used Ball Mill supplier worldwide.A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.

The mill is driven by long high density mild steel shaft and powered by an AC motor mounted to the base of the ball mill. A gear pulley system is used in our model whereby one is attached to the motor the main power supply and the other one is attached to the shaft that is rotates the cylindrical vessel.

Ball 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.
