The shell lining has a major influence on grinding efficiency. It transforms the mill rotation into charge motion and both profile and spacing must be carefully selected to suit each specific mill. When designing a shell lining, Metso Outotec considers the type of grinding, mill size and speed, maintenance schedules, safety, impact levels, efficient use of materials, and many
Aug 06, 2015 The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary portion of a grinding circuit will utilize the lower profile liners. The reason is as lift decreases, friction increases.

It also acts as a grinding medium. The noise of ball mill is 12-15 dB lower than that of steel-manganese liner, which reduces ball consumption by 8-10%, improves the working environment of module and reduces the cost of ball consumption. 4The magnetic lining has fewer faults, and the magnetic lining plate does not need to be repaired.
It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter. And thus, the shell lining has to be adapted to each mill individually.
grinding mills, because it controls the mills throughput and performance. Efficient and effective discharge of pulp/slurry from the mill is the key objective of the pulp lifter design. The modelling showed high wear zones at the pulp lifter discharge outlet. In the incumbent
Apr 09, 2015 Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.

Aug 01, 2000 The grinding mill is probably the most common unit operation in mineral processing. There is, however, much that can still be done in the way of optimization. This paper discusses the results of a well-controlled pilot-scale test in which the performance of a tumbling mill equipped with a conventional rubber lining and lifter bars was compared to a tumbling
May 10, 2019 5 Liner and grinding aid. The liner plays the role of protecting the cylinder and end cover of the mill and lifting the grinding medium. The shape and material of liner have a great influence on the steel consumption of grinding. In addition to the traditional manganese steel liner, there are rubber liner and magnetic liner.
Lining is a special finish on the inner surface of the ore grinding mill protecting it from mechanical and physical damage. The need for lining is due to the fact that when grinding ore, the walls of the mill drum are subjected to continuous exposure to different fractions of ore.
