Roll Crusher - an overview ScienceDirect Topics

Roll crushers are also manufactured with only one rotating cylinder (Figure 6.14 (b)), which revolves toward a fixed plate. Other roll crushers use three, four, or six cylinders, although machines with more than two rolls are rare today. In some crushers the diameters and speeds of the rolls may differ.

Roll Crushers Materials Mechanical Engineering

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).

Roll Crusher for Sale - 911Metallurgist

The standard spring roll crusher have two horizontally mounted cylinders. The set is determined by spacing pieces (shims) which cause the spring-loaded roll to be held back on its sliding mounting from the solidly mounted roll. Modern rolls have both cylinders positively driven by separate motors, so that they rotate inward and downward.

Roll Crusher for Sale - 911Metallurgist

These machines resemble in general form the roll crushers we have described, but they are of course much lighter, and their mechanical details are correspondingly simplified. Instead of the knob-like teeth used on the stone-breaking rolls, these coal crushers are usually fitted with spike-shaped teeth, and the action has more of a tearing nature rather than the heavy slugging and sledging.

Double Roll Crushers McLanahan

McLanahan’s mechanical tramp relief systems employ a spring-and-toggle mechanism that activates whenever an uncrushable object enters the crushing chamber. Once an excessive force is applied to the movable roll, the toggles break open to allow the uncrushable item to pass. The high torsion springs then close the toggles, returning the movable roll to the previous setting. The crusher ...
