Grindability » Laboratory and Analysis Technology » .

As the comminution performance depends on the grinding load (which is different for vertical roller mills in comparison to ball mills), the sample characterization must be adapted as well. For the Zeisel and Hardgrove grindability tests, the feed sample with its precisely defined particle size is crushed by pressure and friction between a grinding bowl and grinding balls.

Grindability For Vertical Mills

Horizontal mill, e.g. air-swept tumbling ball mill, is used to grind high ash content or low grindability coal such as lignite. Besides, a vertical mill is normally used for sub-bituminous or bituminous material. The vertical mills can be sub-classified as roll-bowl, ball-race * Corresponding author.

Cement Milling

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.

Vertical Roller Mills -

As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.
