In a highpressure roller press, two rollers pressurize the material up to 3,500 bar, improving the grinding efficiency dramatically and significantly reducing energy consumption. Highpressure roller presses are most often used to expand the capacity of existing grinding mills, and are found especially in countries with high electricity costs or with poor power supply.
Use of the highpressure grinding roll for finish grinding achieves the greatest energy savings, which can be as high as 50%, compared with conventional tube mill systems. Feed material with up to 4% moisture content is dried in the separator. Material with higher moisture contents is dried in a separate unit, for instance a shafttype flash dryer.
