The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by …
Rubber liners absorb the impact of the larger grinding media and thus protecting – the mill structure and prolonging it's life. Weight: Rubber weighs about 15% of an equivalent volume of steel. This means that a rubber liner system reduces the load on the mill structure and also reduces the basic power draw.

Factors Influence Ore Grinding Mill Efficiency. Abstract. The grinding efficiency is the most important parameter to evaluate machine performance. This article discussed the factors that influence grinding efficiency including article size to mill machine,milling medium,slurry rheological properties,underflow ratio,liner,grinding aid etc.
Grinding operation plays a significant role the national economy, with the cost of breakage and grinding accounting for about 60% of the total investment in a beneficiation plant, and their power consumption accounting for 50-60% [4]. More than 5% of total annual power generation and millions of tons of steel are consumed in ore grinding
Key considerations. Numerous factors must be considered when selecting a mill liner design, including required grinding action, mill size as well as ore and grinding media characteristics, among others. These considerations will help determine the best liner material and geometry. Depending on the mill size and material being ground, a lining ...
A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective ...
The author, Ralph Stokes, described the liners then in use at the Waihi gold mines in New Zealand, where the ore was broken first by stamp mills, with subsequent grinding using tube mills. The hardness of the ore, Stokes explained in his paper, took its toll on the mill liners, the mills themselves being charged with 5½ tons of flints as the ...

Grid Liners A system that appears to be unique to Southern Africa, is pocketed grid liners, where the grinding media packs in the grid structure and forms an integral part of the liner, Figure 3. Often the liners have a flat profile, suited to the high speeds (85% to 90% of critical) that most of the older mills operate at.
Shell liners may be furnished of various materials and of several designs. In each case the material used is the best obtainable, resulting in the lowest cost per ton of ore ground. The liner contours are selected for the specific grinding application and take into consideration liner wear, scrap loss, and mill capacity.
