density of roll crushers are low (0.15– 0.3) Substituting yields a capacity, Q = 1.430 t/hr. The actual capacity of roll crushers is only about 25% of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q = .356 t/hr 2.1.9 Crushing Power

Curves for Screened Feed. The group of curves on the right is charted from screen analyses of the products of crushers receiving screened feed. They are useful in predicting the character of output from secondary and tertiary crushers, and are of great value in the preparation of plant flowsheets, and in calculating vibrating screen capacities.
The work of the roller crusher is continuous. The stone is located between two parallel cylindrical rollers that move toward each other. The friction force between the stone and the roller bites the stone into the roller, facing the stone of the smooth roller. After being squeezed, the stones on the toothed roller are split and squeezed and broken.
Coarse crushers consist of a cone shape bowl with a gyrating central head. Feed is crushed between the cone and head. Dish and puck mills could be considered a laboratory version of this type of mill. Dicers, cutters, crushers, power graters or other mills to produce a uniformly sized product or granules.
