Abstract
A device for comminuting material, such as a roller press, includes rollers positioned adjacent to each other and forming a nip therebetween. One of the rollers may be moveable via an actuator, such as a cylinder or hydraulic cylinder. One or more first accumulators may be attached to the actuator so that fluid is moveable from the actuator to the one or more first accumulators when the rollers are rotated to comminute material passing through the nip. One or more second accumulators may be connected to the actuator as well so that fluid from the actuator may move to the one or more second accumulators when an uncrushable element passes through the nip. Preferably, the one or more second accumulators are configured such that fluid does not pass from the actuator to the one or more second accumulators unless an uncrushable element passes through the nip.
