High-Pressure Roller Mill ECP

High-Pressure Roller Mill ECP

With High Pressure Roller Mills products are produced with a precipitous granule distribution.

The high pressure roller crusher is also called roller crusher or roller press.

The mill feed is transported to the most narrow gap by the counter rotating rollers through friction effects. Both rollers are pressed against each other using hydraulics. This milling force is transferred to the mill feed. Through selective contact of the individual granules are created at extremely high inner tensions which lead to fractures.

The use of the optimal milling force leads to compact mills with extremely low energy requirements.

Because only the outer particles of the material bed have contact with the surface of the rollers, milling that is almost contamination-free is possible.

High Pressure Roller Mills are used in the cases of medium-fine crushing of hard materials such as ceramics, minerals from 5 up to 9 on the MOHS hardness scale, metals and metal alloys.

High Pressure Roller Mills ECP are used in continuous operation or in a closed circuit with screening machines or classifiers.
