Jan 05, 2016 When liners, and double wave liners in particular, wear with circumferential grooves, slipping of the charge is indicated, and this warns of accelerated wear. When the top size ball is smaller than 50mm (2.5) and mill speed is less than 72% of critical wear resistant cast irons can be used. For other conditions alloyed cast steel is recommended.
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is

Feb 13, 2017 Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15 x 21 to 8 x 12. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
Further research is required to include a wear parameter that indicates the liner profile in Morells Model C power equations. It is also necessary to carry out additional research on variable speed drivers (VSD) for mill motors, which could potentially pay back the cost of adding a VSD on ball mills due to the increased grinding efficiency.

Mill mass (t) 260 295 490* * preliminary Technical data Optimized tip speed for longer operating life and lower maintenance costs Wear is generally related to the interaction of two different surfaces and the deformation of the surface material through mechanical action. Tip speed is one of the main wear parameters in a screw.
Alpine SO Ball Mill. Regardless of whether the feed material has a Mohs hardness value of over 4, or is a soft material such as limestone, talc, or baryte -- which would nevertheless cause a high degree of wear in high-speed mills because of hard and abrasive constitutents -- Super-Orion ball mills ensure low-wear and cost-effective processing.
