High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
Jan 25, 2011 · When burned by a sugar mill, bagasse, the fibrous material leftover after juice is extracted from sugarcane, usually produces enough electricity to power all of the mill's operations and then some. For every 10 metric tons of sugarcane crushed, a sugar factory produces nearly 3 metric tons of wet bagasse.

The high fat content of these materials provides lubrication, but this does not soften the fibre sufficiently to avoid excessive heating caused by friction. The ring die and rolls of a pellet mill exposed to high temperatures show metal fatigue and must be replaced often.
Energy saving processes and technologies within the mining and minerals processing industry are gaining increasing attention. Since its introduction in 1985, high pressure comminution with roller presses (also known as HPGR) has been proving its significance in energy efficient crushing and grinding circuits in the cement industry.
Medium pressure, high flow, dip in pressure curve, efficiency higher than radial fans, power rises continuously Low pressure HVAC, packaged units, suitable for clean and dust laden air / gases Tube-axial Medium pressure, high flow, higher efficiency than propeller type, dip in pressure-flow curve before peak pressure point. HVAC, drying
High Pressure Grinding Rolls (HPGR) . Grinding of material in HPGRs has proven to be more cost efficient as compared to conventional mills and crushers. Especially downstream processing stages such as ball-milling are more energy-efficient due to the finer product size distribution coming out of the HPGR and the additional effect of micro .
HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores. .

"The increasing adoption of HPGR in the mining and cement industry is expected to propel the market growth" The global High Pressure Grinding Roller (HPGR) market is anticipated to witness a robust growth owing to the increase in the adoption of the mining and cement industry.
To make the mill more efficient, some roll mills are equipped with a system allowing to guarantee a high pressure (10-50 bar) in between the rolls. It is also mandatory for these mills to have a spring system allowing to release the pressure if the constraint is too important ( foreign body for example) and avoid mechanical damages.
Vertical roller mill grinding speed is slow, so the Vertical roller mill powder grinding capacity is small. In other words, when the material contains relatively large amount of water, the material in the vertical mill machine will be prone to adhesion, but also very easy in the delivery of the material during the blockage.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill
