A braking system for use with a crusher having a moving crushing member and a stationary crushing member. The braking system is positioned and is operable to restrict rotational movement of the moving crushing member. The braking system includes a braking disc or plate and one or more braking yokes that each include a magnetic member, such as a permanent magnet or an electric magnet. The braking disc is formed from an electrically conductive material and is perpendicular to the magnets of the braking yoke. Relative movement between the braking disc and the braking yoke induces an eddy current in the braking disc. The induced eddy current creates a magnetic force that opposes rotational movement of the moving crushing member. The braking system can be used with a compact eccentric crusher to restrict the rotation of a crushing roller during an idle mode.
A crusher for crushing a supply of mineral material, the crusher comprising:
A braking system for use with a crusher having a stationary crushing member and a moving crushing member that are spaced from each other to define a crushing gap, the moving crushing member including a crushing roller mounted to an eccentric shaft such that a rotation of the eccentric shaft creates an eccentric movement of the crushing roller relative to the crushing gap, the braking system comprising:
A compact eccentric crusher having a stationary jaw and a crushing roller mounted to an eccentric shaft such that a rotation of the eccentric shaft creates an eccentric movement of the crushing roller into and out of a crushing gap, the crusher comprising:
