The blow bars are locked in modularly adapted to the individual requirements and position in the holders by means of wedges, which can wishes of the operators even up to a fully automatic be easily removed for blow bar changing. The rotor mode. Depending on the properties of the feed body together with shaft and bearings forms the material, the crushing ratio and the desired heart of the impact crusher. requirements on the product grain size, feed sizes of up to 450 mm and throughput rates of 700 t/h max. HAZtronic are possible. With the HAZtronic system, the crusher can be controlled and adjusted from the main control panel. Hydraulic suspension of the impact aprons All the settings which determine the end product Due to the hydraulic suspension of the impact aprons can be input and called up at the touch of a button not only a simple and fast adjustment of the opening without interrupting operation. This means that widths is guaranteed but also an overload protection. immediate reaction and adjustment to varying As soon as the crushing forces in the crushing operating conditions can be effected at all times to chamber exceed a predefined limit value, the impact ensure optimum productivity. aprons retract and thus protect the built-in parts, such as rotor, blow bars and impact aprons, from potential damages. After the retracting procedure the impact aprons move back in a controlled manner into their original position, so that the crushing operation can be continued without interruption. In addition the hydraulic suspension offers the comfortable possibility of a simple readjustment and a quick on the spot-adaptation to the individual procedural conditions on the machine or from the switchboard.
