Working Principle and Characteristics of HFCG Series Roller Press 1.Roller press follows material layer grinding principle.Material is fed in between two opposite rotating rollers and sent to the pressure zone by roller surface friction and material gravity.
A very high hydraulic grinding pressure enables the material bed to be ground by crushing. One of the rollers is mobile and the air gap adjusts automatically in relation with the input material and piloting of the hydraulic pressure. The piloted hydraulic shock absorption coupled with the pressure pulsation (POITTEMILL patent) reduces shocks and vibrations that could damage the anti-abrasive coating and .
DEFINITION: ROLLER PRESS. Roller press is a highly efficient communication system where the feed material is exposed under a very high grinding pressure between two solid rollers [ one fixed and one moving ] for a short time due to compression. The high pressure causes formation of micro cracks in the feed material and generates a substantial amount of the fine material.
Since 1984, roller presses – also referred to as grinding rolls – have increasingly been used for crushing medium-hard and hard materials. Today, they are used in the coarse grinding, hybrid grinding and fine grinding of limestone, cement clinker, ores, coal and other mineral material. The advantages of a roller press over conventional size reduction machines, e.g. tube mills, include a ...

Under actual operating conditions, when using a material crushing high-pressure roller press for energy saving purposes, the raw material (if necessary, together with the sifter grit) is deposited onto the roller press, which was operated using a very high pressure. The wear problems for the roller press, the disagglomerator, and the sifter are tremendous when using this process. On the other hand, when .

Reduce steel consumption. When grinding cement, the ball mill has a yield of 300~1000g/t, and the grinding system of the roller press has a yield of 0.5g/t, so it can meet the requirements of white cement. Low noise. The ball mill noise is above 110 dB, while the roller press is about 80 dB.
In a pre-grinding setup, the Hydraulic Roller Press grinds the fresh feed and a specified amount of recirculated pressed flakes. This material mix then undergoes finish grinding in a conventional ball mill circuit. In comparison to a conventional ball mill system, this configuration provides an increase in production of approximately 25 per cent and a reduction in specific power consumption of .
The Kompaktor is also called roller press, roller compactor or dry granulator. If it is used for crushing, the Kompaktor is also called high pressure roller mill. Compacting is understood to be the compression of powder between two synchronised, counter rotating rollers. Here, adhesive forces between the product particles are created under high pressure between the rollers. If the compaction takes place alongside .
