The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
Single Roll Crushers. Williams single roll crushers reduce via a combination of impact, shear, and compression. The rolls are always toothed in patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities and are particularly well suited to be used as lump breakers.
The perforated Roller reduces re-absorption continuously by removing the juice under pressure at the perforation points. The Juice removal is extra from the juice removed in normal function of an ordinary Roller, Thus perforated Roller transforms any Mill, old or new into a supper Mill BENEFITS:
Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

Primary Extraction. a) The greater the extraction of sugar in the first mill the less difficult in the task left to the following mills to recover more sugar by the trouble some step of wet extraction and better is the overall extraction of the tandem. b) It is proved that a gain of 1% in primary extraction gives a gain in total extraction of 0.12% in 12 roller tandem, 0.10% in 15 roller ...
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.

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. .
