One currently on the market use ordinary grinding ball mill, the main bearings are "Babbitt bearings" , running resistance, fuel consumption, and needed a large mill bearing with lubrication station, maintenance difficulties, grinding one ton of ore, the power consumption of 25 kilowatts (KWH); now the energy-saving ball mill main bearing rolling bearing, grinding ball mill power consumption of 1 ton of ore 18KWH about.Dry oil lubrication, save 80% lubricant.The large mill to remove the main bearing lubrication station, maintenance ball mill for one year only once, the operating rate can reach 100%.  

Alicey999 Ordinary ball mill linings, bar, ladder-shaped, wavy, the shortcomings of these types of liner liner wear to a certain thickness, bending, deformation, lead ball mill can not be used; another The disadvantage is that the surface shape of the liner, the contact area of he ball and lining, ability to grinding, the grinding efficiency is low, resulting in low production of the mill.Recommended dual U-shaped liner, the advantages of this lining is ball mill corrugated along the circumferential direction of the mill shell; along the mill axis of the trench.Mill in operation, the grinding media to the lifting height, to improve the grinding efficiency with the contact surface between the liner, the liner than ordinary grinding opportunity to increase production in more than 6%.

Mill Plain bearings advantages: the ball mill grinding equipment, generally use plain bearings as main bearings, bearing lining with babbitt material.Because it has good friction compatibility, compliance and embedded, such as ball mill overload is very suitable jaw crusher for, low and associated with the impact of the phenomenon of machinery and equipment and therefore has been widely used in production. The shortcomings of the Mill Plain bearings: 1.High energy consumption.Sliding friction is much greater than the rolling friction, the friction caused by a lot of heat, consume large amounts of energy consumption.According to the calculation, the sliding bearing ball mill, the journal and bearing contact area of least 75%.Spherical bush sliding bearing friction power is theoretically about 1/3 of the total installed capacity. Two.Difficult to maintain.Sliding bearing structure is simple, but Cone crusher price complex process of casting babbitt, subject to the ratio of the babbitt material, melting, cleaning of the bearing base, preheat, hanging curium and babbitt casting and scrape, each process stringent technical requirements, the slightest mistake, that is likely to cause scrapped.
