Inhouse plastics recycling solutions provider Rapid Granulator, Bredaryd, Sweden, presents the biggest innovation in slow speed granulation in years with its OneCUT PRO, which offers less dust, less noise, less energy consumption and significant operational benefits.
Amid growing demand for efficient and reliable recycling solutions, OneCUT PRO allows injection molded plastic processors to adjust the rpm range when granulating at a slow speed from the standard 25 rpm to a bandwidth of 15-35 rpm (plus/minus 40 percent rotor speed) for optimal quality regrind.
With the vast majority of processors running at under capacity, the new machine, which uses the new Rapid FlexiSPEED system, means less dust, less noise and significantly less energy consumption. For processors facing capacity limitations, operating at a higher speed level will allow them to overcome capacity constraints, boosting operational output. The torque level of the machine is maintained, regardless of the speed at which it is running.
Further benefits of the new machine include the operator-friendly “Open Hearted” design through the patent pending QRR (quick rotor release) system and the use of an innovative energy saving technology.
While knife granulators are conventionally used for granulating softer materials and run at a speed of 200-250 rpm, processors of brittle materials such as glass-fiber reinforced plastics primarily rely on slow speed granulators. These processors have, until now, been limited to running their granulators at 25 rpm, regardless of the specific material that they are processing.
Running the new machine at a lower speed of 15 rpm helps to improve the quality of ground highly brittle materials through minimizing dust generation. But there are noise reduction advantages too, as noise levels correlate closely with cutting speed. By reducing rotation speeds from 25 rpm to 15 rpm, noise levels can be reduced in many applications by 3-5 dba. This means about a 50 percent reduction in actual noise pressure on the ears of factory workers.
A further advantage of OneCUT PRO is the implementation of EnergySmart, a new system that can lead to an about 80% percent reduction in energy consumption. This function allows the operator to stop the machine from running when accumulating materials, rather than having it run continuously. With Rapid Stop & GO mode, the granulator will stop and go in intervals, so there is zero energy consumption and no noise during pause mode. When EnergySMART is implemented together with running the machine at a rotor speed of 15 rpm, the maximized energy saving is reached.
