Sustainable cement production—present and

01.07.2011  In addition to the ball mill, high-pressure grinding systems such as vertical roller mills (VRM) or high-pressure grinding rolls (HPGR) are in use today for cement grinding. The specific energy demand of these grinding systems is comparatively low, but the cement from high-pressure mills shows slightly different properties in terms of its particle size distribution (PSD).

5 Things To Know About High-Pressure

High pressure does not mean high flow. Most pumps offer anywhere between 6 gallons per minute (GPM) up to 40 GPM or more—if you’re using large indexable end mills with dozens of coolant holes, be sure you invest in a pump that can keep up. Although HPC offers significant benefits, more is not always better. A variable speed pump will allow you to fine-tune the output pressure according to the needs of
