A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the Rolls. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. 10/18/201514ch42, 14ch24 4

When applying these ideas, the established roller crusher, previously modeled by Austin et al. (1980), and usually used for soft ore or coal breakage was used as a starting point. The crusher was then retrofitted with hydraulic cylinders to increase the pressure between the rollers. This was the predecessor to the high-pressure grinding rolls ...

The typical throughput on every modern crusher is a 6 to 1 reduction ratio, gyrator, jaw, and roll. The exception is a hammer mill. A hammer mill will reduce to finer sizes due to no "nip" angle associated with the others. Check out Mount Baker Mining and Milling, Or if you have a steel shop, make your own.

The material is fed at a uniform rate along the total width of the drums. The nip angle is the important parameter here for the crushing to take place. The nip angle of the feed material is further dependent on the coefficient of internal friction of the material which is essential for the material to pass through the drums and get crushed.
