The toothed roll crusher is suitable for crushing raw coal in coal mines, coal preparation plants and other industries (allowing less than 30 of coal gangue in raw coal). The crusher is also used to break other brittle materials whose hardness is similar to that of raw coal.
Roll crushers have a theoretical MAXIMUM reduction ratio of 4 1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1 2 inch. Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls.
