The maximum amount of coal for pulverizing with raw mix was found to be 10 `of the raw mix as calculated from the calorific value and the heat of clinkerization of coal. The coal residue left after burning was utilized in the cement raw material for which a
Click to chat· 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.
