Threepiece "compressiontype" liner bolt sealer is designed to prevent leakage of slurry. or dust from mill liner bolt holes. Used in conjunction with Grade 5 (highstrength) bolts, this assembly is generally applied to rod mills over ′ in diameter and ball and. autogenous mills greater than ″ in diameter.
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.
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 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 ...
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.

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
highenergy collision between liner and milling media was the principal cause for mill vibration and liner wear. Xie and Zhao [3] applied DEM to study the influence of fluid, friction coefficient, and milling speed on the wear rate in a planetary ball mill. The results showed that drag force and torque
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.
