S-Max 3 This series of screenless, low-speed granulators from Wittmann Battenfeld efficiently grinds engineering resins, styrenic resins, acrylics and glass-fiber-reinforced plastics down to granules from 4mm to 10mm in size. The compact granulators feature a hopper made with sound-dampening material between sheets of stainless steel that reduces noise when plastic pieces hit the hopper walls. They also have audible and visible alarms to alert operators when the regrind bin is full.
What’s new? An optional built-in feeding shaft. The new feeding shaft is independently driven and keeps large runners and parts in motion. It has elongated hooks to precut the parts and runners and push them into the cutting chamber.
Benefits Better feeding. The feeding shaft helps prevent bridging and nesting, especially of flat parts and long runners. It reduces downtime due to material backing up or overflowing. Additionally, because the shaft size-reduces the plastic before it reaches the cutting chamber, the use of a smaller, less-expensive granulator may be possible.
