Mills belong to a class of equipments that accomplish comminution of materials in the fine range. There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns.

What are the types of coal? There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal.

Cement industry: quality of coal major concern-II. Cement units on coal: Table 13 shows the cement units converted to coal. In north zone, from 14.332 Million Tons, 12.086 Million Tons capacity is on coal. In south zone, 2.816 Million Tons capacity is on coal from total 4.948 Million Tons.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.

Type II cements are limited in C150M 85 to a maximum of 8 percent by mass of tricalcium aluminate a cement phase often abbreviated C 3 A which impacts a cement's sulfate resistance Certain oxides are also themselves limited by specifications For example the magnesia MgO content which is limited to 6 percent maximum by weight for portland ...

additive) are proportioned and ground in Cement mill (one Closed circuit ball mill in line 1 and two Roller press+closed circuit ball mill in line 2) based on the type of cement to be produced keeping the quality of cement equal or above the required standard. For instance (Clinker+Pozzolana+Gypsum) are proportioned and milled

Vertical coal grinding mill integrates crushing, drying, grinding, powder selection and conveying.; It has simple system and compact structure. Vertical coal mill covers an floor area about 50% of the coal ball mill with the same specification.; Coal vertical mills can work in open-air environments, greatly reducing the cost of investment. The design of the vertical coal mill system is simple ...

Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 65-80 0 C) will depend upon the type of coal ground. Some residual moisture in fine coal is recommended (Graph below) to minimize the potential of spontaneous ignition of fine coal, which will again vary for different coal types as below:
