Our smaller spinner can cast a bearing with an outside diameter of 36" and up to 1500lbs. The size, mass and configuration of your bearing, will determine the machine we use.
WhatsApp: +86 182036953771. Introduction. Planetary ball mills provide high energy density due to the superimposed effect of two centrifugal fields produced by the rotation of the supporting disc and the rotation of the vials around its own axis in the opposite direction [1].During operation, the grinding balls execute motion paths that result in frictional and impact effects.
