Abstract
A crusher device includes a frame, a rotating mechanism positioned in the frame, and a plurality of curtains connected to the frame. The curtains are spaced from the rotating mechanism to define a passageway along which material moves while being crushed. A first curtain is connected to the frame via at least one first cylinder. The first curtain is connected to a second curtain via at least one pivotal connection and at least one second cylinder. The at least one second cylinder is retracted automatically when the at least one first cylinder is forcibly retracted to adjust spacing between the first curtain and the rotating mechanism due to an uncrushable. The automatic retraction of the at least one second cylinder rotates the second curtain away from the rotating mechanism. Such movement widens the spacing between the rotating mechanism and the curtains minimizing damage from tramp or uncrushables.
