a high-pressure crushing process. Carried over to the principle of dry comminu-tion of concrete rubble in a Loesche-type roller mill, the selected disintegration process is as sche - matically represented in Fig. 2. The feed material (1) is dumped onto the centre of the grinding table (2) and then carried under the grinding roller (3)
@misc{etde_6089526, title = {High-pressure roll mills for cement raw meal, coal and lime grinding} author = {Thurat, B, and Wolter, A} abstractNote = {The many different possible grinding system layouts comprising a high-pressure roll mill (or roller press) are referred to the basic types: pre-grinding, hybrid grinding, partial finish grinding and finish grinding.
Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.

The high-pressure roller mill is used as a material grinding equipment with excellent performance in mining enterprises. It uses the principle of static pressure pulverization. However, because the equipment is in operation, the force of each part is large, resulting in large vibrations.
The high pressure grinding roll machine comprises a pair of counter-rotating rolls mounted in a sturdy frame. One roll is fixed in the frame, while the other is allowed to float on rails and is positioned using pneumo-hydraulic springs. The feed is introduced to the gap between the rolls and is crushed by the mechanism of interparticle breakage.
