For 60 mm (″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately D in meters (for D in feet, divide D by ). Wave height above the liners from to 2 times the liner thickness. Rubber liners of the integral molded design follow the cast metal design.
key factors affecting mill throughput and grinding efficiency: mill speed, ball loading, and liner lifter face angle (angle between the lifter face in contact with a grinding ball and the lifter base). Its central hypothesis is that face angle drives a ball mill's grinding efficiency and throughput independently of the type of liner used.
Ball mill liners are essential components in the operation of a ball mill.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

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. When the grinding media contacts different shapes of ball mill liners, the movement state will also change, thus enhancing the crushing ...

Uses of a Ball Mill Liner. The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.
Effect of lifter number on the liner torque and baffle torque of the experimental ball mill at different mill speed between 60% and 100%. ... A new approach to optimising the life and performance of worn liners in ball mills: experimental study and DEM simulation. Int. J. Miner. Process, 84 (2007), pp. 221227.
2) Coal field: feeding chute and funnel liner, hopper bushing, fan blade, pusher floor, cyclone dust collector, coke guide liner, ball mill liner, drill stabilizer, spiral feeder bell and base, tumbler bucket liner, ring feeder, dump truck floor. The coalfield operating environment is harsh, and there are certain requirements for the corrosion ...
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
Ball mill liners play a crucial role in the milling process by protecting the mill shell and reducing wear and tear on associated components. The type of liner used, as well as the size and shape of the mill and milling conditions, are critical factors to consider when selecting the right liner. Choosing the right liner for your ball mill and ...

According to Swart et al. [9], ball mills are mostly used because of their very high size reduction ratio, although they have a very low energy efficiency of about 20%. According to Conger et al. [10], many factors affecting ball mill efficiency include mill design, liner design, mill speed, charge ratio, and grinding media properties.
The type of ball mill liner known as a grate liner is designed for discharge efficiency. It allows the discharge of ground materials via slots. With the Magotteaux range of alloys and their experience a longer lifetime and optimal grinding can be achieved. Designs of grate liners depend on their drilling pattern, mill speed, grinding media ...
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.
A longer lasting mill liner means less downtime for maintenance or new liner installation. A mill liner that occupies less space allows increased volume within the mill and leads to greater grinding capacity and throughput potential. Safer maintenance. 50% lighter and have 50% fewer parts on average when compared to traditional cast steel liners.
