High–low double wave ball mill liners – These are a refinement of the wave liner, Figure 5. This was applied to Cadia Hill Gold Mine through evaluation of their existing wear profile and wear rate, and provided a more consistent wear profile through the liners working life.
The ball mill, an intermediate and fine-grinding device, is a tumbling drum with a 40% to 50% filling of balls. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.
The profile can be better customised to suit mill speed and filling and therefore optimise performance It allows more material in the lifter for agiven base width But mill must run only in one direction High-low double –wave ball mill liner These liners are a refinement of the wave liner Provides a more consistent wear profile and wear rate ...

The mill liners could be manganese steel or NIHard or high carbon steel either as grid or solid liners. Hard rubber or hard synthetic liners, 65–75 mm thick, are common. Liner surfaces can be smooth, ribbed or waved. The waves are usually 65–90 mm above the liner thickness, for double wave liners and 60–75 mm for single wave liners.
Rod mill liners are subjected to severe impact. Premature breakage and scrap loss are reduced by correct selection of liners for the specific grind-ing duty. Additional benefit results from use of a backing material, such as rubber between the lin-ers and the mill shell. Wave Type Mill Liners Wedge Bar Or Lifter Bar Mill Liners
Mill liner design experts agree that tumbling mill shell liners with multiple wave contour provide the optimum performance. The distance between wave crests, the height of each wave and radius of valley between each wave crest are important for grinding efficiency and wear rate of liners.

The design and manufacture of pharmaceutical tablets is a complex multi-stage process whereby formulation scientists ensure that the correct amount of drug substance in the right form is delivered at the appropriate time, at the proper rate and in the desired location with its chemical integrity protected to that point. Most drug substances do not possess the required properties which …
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.

Double wave liners; Shell liners; Feed headliners; Discharge end liners . ... The rods grind the ore by tumbling within the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and ...
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

The mill is normally used for grinding of ores. Lining of the cylinder plays very important role. It protects the mill from abrasions and at the same time it helps in lifting of the material from the bottom of cylinder. The types of lining are (i) smooth liner, (ii) wave liner, (iii) ship lap liner, (iv) step liner, and (v) Osborn liner.

WAVE BALL MILL SHELL LINERS The wave type liners are made with the lifter and liner sections cast integral. They may be of cc-alloy, manganese, chrome-moly, chrome nickel steels, or, where practical, chilled iron. These liners offer a continuously undulating surface and are held in place by means of bolts through the high part of the liner.
