f The cement making process can be divided into. three sections. 1. The first section is a raw material preparation. where massive movement of material, intensive. mixing and size reduction takes place. 2. The second category and most important is the. formation of "clinker" which is made in the kiln at.

Several basic assumptions are made in modeling of the grinding process in various types of mills and milling circuits. Most frequently, it is assumed that the mill's content is uniform and thoroughly mixed by the rotation of the mill and the movement of the grinding media [44]. In this case the model is known as a perfectly mixed model.

The crusher product is ground in an SAG or AG mill (Giblett, 2019). AG mills crush the ore without the need for iron or steel grinding media. They are used when the ore is hard enough for the tumbling ore to grind itself. In SAG milling, ∼ m 3 of 13 cm diameter iron or steel balls are added into the mill per m 3 of ore (, 15 vol ...

The mill feed ore is sampled after a continuous process of systematic mixing, crushing, grinding, and pulverizing in the beneficiation plant. The fragment sizes have attained a best possible interlining homogeneity and uniformity at (−) 100 mesh size, and are collected by automatic sampler at 15/30 min intervals after ball/rod mills.
