Cyclones Don't Do Any Grinding - Blog - Orway .

There are two primary control schemes for operating closed grinding circuits based around the characteristics of hydrocyclones. The cut-point of a cyclone is influenced by both the flow (pressure-effect) and slurry density (hindered settling-effect). This gives rise to operation using one of the two primary philosophies, either constant flow and variable feed density, or constant feed density ...

Effect of grinding aids in cement grinding

A number of grinding aids ar e available on the market. The most suita ble grinding aid for a certain grinding process has to be determined by full scale test runs. The use of grinding aids in both open and closed circuit systems will improve the control of the grinding process, increasing the Blaine number (finer product).

The cement mill

Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the ...
