May 19, 2020 7:31 am The ball mill liners are located on the inner surface of the ball mill barrel, which protects the barrel from the direct impact and friction of the grinding media and the material. The ball mill liners' material and shape are different base on requirements.
The liners are from 50 to 65 mm thick (2″ to ″) with the waves from 60 to 75 mm (″ to 3″) above the liners. The replaceable lifter bar design made of either metal or rubber in about the same design proportions can be used.
Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.
Vertical roller mills offer supreme grinding with high energyefficiency. Whether grinding raw coal, clinker, cement and/or slag, we have a VRM solution to suit your grinding needs. What's more, our online condition monitoring services enable you to adopt a proactive maintenance strategy for your OK™ and ATOX® mills that eliminates ...

Longlasting wear life with Orebed™ The inside and the door of your Vertimill® are protected by Orebed™ linings. Orebed™ consists of a series of powerful magnets embedded in rubber. The ferromagnetic material in the mill load forms a layer that protects the lining. Installing Orebed™ is fast and easy since no bolts are needed,
Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.
Megaliner™ is now available for all sections of horizontal mills: the head, the shell and the discharge system. Read more about Megaliner for discharge systems
There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. 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 ...
