MT 221: 3.0 COMMINUTION - CRUSHING 2015 T.P Chanda 4 The crushing angle is the maximum angle between the converging jaw plates. It is usually between 18 o and 24 o.If the set is reduced, the crushing angle is increased. The crushing angle may never exceed the angle of nip, because then the rock particles would not be nipped and crushed, but just bounce up and down on the swing jaw.

Selecting optimal crushing equipment can be difficult. Luckily there are tools and software available that simplify weighting different options and help in making decisions. The backbone of all these analyzes are careful calculations that take into account the capabilities and constraints of different crushers and operational requirements.
A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the ...
For primary crushing with a reduction ratio of 6 to 1. When a relatively coarse product is desired, top size usually larger than 38 mm (1 1/2") Closed Circuit Crushing System To control top size from a single crusher operating in an open circuit, material must remain in the crushing chamber until the material is reduced to top size.
Crushing machine being loaded with construction debris by an excavator. Wet Methods Wet spray methods can greatly reduce the silica exposure levels of operators and laborers who work near crushers, tending the equipment, removing jammed material from hoppers, picking debris out of the material stream, and performing other tasks.
