Abstract
A jaw crusher having a dynamically adjustable tramp iron relief system is disclosed. A moveable jaw and a stationary jaw define a crushing chamber, with a lower portion of the moveable jaw cooperating with a lower portion of the stationary jaw to define a closed side setting gap. A hydraulic tramp iron relief system operatively connects at least one of the jaws to the frame and is arranged to permit uncrushable material to pass through the crushing chamber by permitting the lower portion of the jaw to shift to a shifted position in which the gap is increased. The tramp iron relief system includes an adjustable hydraulic cylinder, the hydraulic cylinder arranged to permit the gap to be adjusted during operation of the crusher.
