Electrical features include: a user friendly 7-inch colour touchscreen interface; safe 24 volt DC panel powered design; an electric actuator used for cutting chamber maintenance access; an electrically operated rotor lock that can be acti- vated to prevent the rotor from rotating for safer


redesigned to cope with the most demanding heavy-duty size reduction applications in a single step. The company says that these machines are manufactured with rotor widths ranging from 23½ to 78¾ inches and with drive capacities between 60 and 420 HP. The knife design is segmental, thus ensuring a quick and easy exchange of the cutting tools. SMS granulators are equipped with a third bed knife called a deflection wedge. When the deflection wedge is removed larger, bulky items can be easily accommodated. Typical applications for these heavy-duty granulators are claimed to be heavy, thick-walled semi-finished products in PE, PP, POM and PA, pipes with high wall thicknesses and large purgings. They are also well suited for difficult to grind materials such as aramid and carbon fibres and composite materials. According to Herbold, another key feature of the SMS is the ability to adjust knives outside of the
