Single and Double Rotor Bar Crusher

These types of crushers have rigid breaker bars extending the full length of the rotor with a combination of fixed bars and moveable breaker plates to permit the passing of uncrushable material. Four or six rows of bars is the norm, spaced equidistantly around the roller. The top ends of these moveable plates are hinged and the lower end suspended on spring loaded adjustable bolts. This will allow the gap to be varied to determine a particular product size. Alternatively breaker plates can be fixed in one position arranged to give the rock particles maximum impact when cast against them.
