Roll Crusher an overview ScienceDirect Topics

A distinct class of roll crushers is referred to as ‘sizers.’ These are more heavily constructed units with slower rotation, and direct drive of the rolls rather than belt drives. They have a lower profile, allowing material to be easily fed by loaders, and are a good choice for portable crushers at the mine that reduce the coal in size for conveying to the preparation plant.

Roll crushers do, however, give a very close product size distribution, and if the ore is not too abrasive, they do not have high maintenance costs. 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.
