Grinding Mill Liner Grinding Mill Charge Motion inside Mill Application Grinding can be either dry or wet. Dry grinding has limited application because the use of water may be inhibited due to process limitation or it may bring about a change in the chemical composition. Grinding is mostly wet; Ore is ground by making it slurry with water.the mill and the relatively long lifespan of its liner, the optimization of the liner by the classical way, i.e. experimental testing, is a difficult and slow process. In this thesis, a procedure for predicting the charge motion and the power draw of a ball mill

Mill liners protect the mill shell from wear and transfer energy to the grinding charge. Careful balance is needed to optimise these differing requirements, as poor liner design has detrimental effects on milling performance – and on mill liner life. Mill liners developed by Multotec include Ball Mill Liners, SAG Mill Liners, AG Mill Liners ...Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

Summary The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium (e.g. steel balls) put in the shell, and has a simple ...For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
