Ball Mill Working Principle To be chosen according to the grinding material material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body when the ball mill cylinder rotation time grinding body due to inertia and centrifugal force the effects of friction making it attached to the cylinder liner on the cylinder body away when taken to the height of a
“These trunnion bearings are selected based on the grinding mill size and type in addition to the site conditions and output required of the mill ” says Fabio Rebecchi Product Manager for NTN CBC Australia “In these instances we’re seeing a trend for extra large spherical roller bearings which are critical in ball mill application
From a bearing point of view there are two bearings at the end of the shaft on the pinion and there are two bearings on either end of the ball mill And obviously the ball mill bearings are massive in size – which is why they get a lot of attention and are expensive to manufacture ” explains CBC Australia Engineering Manager Anthony O
