In cement clinker grinding, HPGR have recently been used prior to ball mills so as to decrease energy consumption in conventional ball mill alignments. Patzelt (1992) stated that certain HPGR-ball mill arrangements consume 30% less energy than those with only ball mills.

Clinker Grate Cooler for Cement Plant

The clinker is quenched from 1300-1400 C to below 100 C in a few minutes. The traditional coolers are divided into3 types: rotary type, vibrating type and push type .

What is Cement Clinker? Composition, Types Uses

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400C-1500C in the rotary kiln.

Stage 4: Finish Process

The output achieved by a ball mill system varies with the mill power, the fineness of the product and the hardness of the clinker. A typical general purpose Portland cement of fineness (specific surface) 340 m.kg -1 ground on an efficient closed-circuit ball mill system requires around 32 kWh per tonne, so a 10 MW mill would produce 313 tonnes of this per hour.

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.
