Roll Crusher - an overview | ScienceDirect Topics
Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size. Both open and closed circuit crushing is employed.

Roll Crushers | McLanahan
The impact force occurs as the material enters the crusher and is impacted by the rotating roll. Shear and compression forces occur as the feed material is pulled between the crushing plate and/or crushing rolls. Depending on the feed size, material is fed into the crushing chamber and encounters a single or a pair of rotating rolls.

Optimal Roll Crusher Feed Size Unless the rock is exceptionally friable the maximum thickness of the feed should not exceed that thickness which the crusher can effectively nip between the advancing slugger teeth and upper part of the anvil; the only breaking done on top of the roll should be the beam action breaking of long slabs.
Roll Crushers - ScienceDirect
Jan 01, 2016 · The feed to roll crushers is usually dry. Moisture tends to clog the crusher and could result in the formation of hard crust, which impairs operation. Hence, dry crushing is preferred. Sometimes, water is added between the rolls, which help to prevent formation of the crust and also to remove the hard cake that tends to form on the roll surface.
In the double roll crusher the feed is distributed by a feeder over the entire roll width. The material is drawn into the crushing gap by appropriately shaped teeth projecting from the rolls. For special applications, teeth of different heights are available at option. The anticipated maximum feed size determines the roll diameter.
