Product: High-pressure grinding rollers

During high-pressure grinding in roller presses coarse materials, such as cement clinker, ore or limestone, are briefly subjected to very high compressive forces. The sheets thus produced can be ground and thus reduced to the desired final particle size with minimum energy requirements.

High-pressure grinding rollers (HPGR) are employed in various combinations with other equipment for preliminary and finish grinding. Energy savings is the most important factor for using this technology.

Depending on the grinding system used, capacity improvements of up to 250 per cent and/or a reduction of the specific energy consumption of up to 40 per cent can be achieved. To suit the respective application, three different types of rollers are available:

• Solid rollers
• Rollers with tyres
• Rollers with segments
