Press Side Granulator
Our Press Side Granulators are available with a wide range of automation components such as special hoppers for combination robotic and manual feed; conveyor feed; oversize part, etc.; vacuum take-off bin for regrind evacuation and blower evacuation systems of various sizes, complete with unloading bins and cyclone separators.
Counter-slanted rotor and bed knives provide a high shear slicing action that achieves clean, uniform granulate, with very low plastic dust and fines at high throughput rates with less noise and fines, lower energy consumption and heat buildup. The rotor diameter of Press Side Granulators is greater than the feed opening, allowing clear, unobstructed access to the cutting chamber to utilize every inch of the cutting circle. This unique design maximizes granulator capacity and throughput by eliminating bottlenecks at the entrance, and increasing the effective screen area.
Large Part Granulator
The Hosokawa Polymer Systems Large Part Plastics Granulator is designed to recover large, thin-walled parts including housings, helmets, blown bottles, automotive body and bumper components, as well as large volumes of smaller parts and accumulated sprues and runners. The Large Part Granulator Double Angle Cut™ Counter slanted rotor and bed knives produce a slicing action for clean, uniform granulate at higher throughputs with less energy consumption and heat build-up.
Double Angle Cut™ Counter-slanted rotor and bed knives provide a high shear slicing action that achieves clean, uniform granulate at high throughput rates with less noise and fines, lower energy consumption and heat buildup. The steep angle approach of the rotor pulls material into the chamber for faster processing with reduced flyback. Two-blade & three-blade rotor configurations provide optimum granulating efficiency and throughput for your specific application.
Premium Shurfeed Granulator
The Premium Shurfeed Granulator is a press side & central plastics granulator designed for quiet operation. Hosokawa Polymer Systems has taken its proven Shurfeed granulator chamber design a giant step forward with refinements that dramatically improve operating efficiency. A specially designed back wall smoothes material transition to the cutting circle to practically eliminate flyback while reducing overall shock to the system, noise and energy usage as well.
Another improvement: New Premium Shurfeed Granulator rotors run at slower speeds to decrease the velocity of materials in the chamber, reducing the ricochet effect. In total, operating efficiency achieved with this new chamber design delivers substantial improvement in noise reduction, flyback and energy efficiency. Polymer Systems has system-matched chamber, rotor and drive components in this new line of granulators to deliver efficient, trouble-free performance with the lowest possible power requirements.
The original Double Angle Cut configuration which includes three steep-angle rotor knives and two counter-angled bed knives, provides a high shear slicing action that produces a clean, uniform granulate at high throughput rates with low energy consumption. The new rotor design also puts more weight at the outer diameter to maximize use of kinetic energy and inertia for easier cutting of materials without jamming. Polymer Systems uses larger sheaves to further increase inertial forces.
When specified, a blower evacuation system can be fitted inside the machine’s sound-proof enclosure for quieter operation and to minimize floor space requirements. The cyclone is mounted on the back of the granulator, so it doesn’t require a separate stand and is portable with the granulator.
Heavy Duty Granulator
Designed specifically for continuous high volume recovery of the toughest materials, Polymer Systems’ heavy duty machines are precision machined with heavy steel plates and stress relieved weldments throughout. Massive construction of the cutting chamber, rotor and drive assembly provides maximum rigidity, allowing close knife settings without fear of misalignment or machine damage due to shock loads or continuous operation.
Only Polymer Systems’ granulators have a clear, unobstructed feed opening equal to rotor diameter for maximum performance through every inch of the cutting circle. This unique design maximizes granulator capacity, eliminates bottlenecks at the entrance to the cutting chamber and dramatically increases effective screen area for fast throughput. A special sound-deadening composite material is used for hopper walls on all Press Side, Large Part, Shurfeed 2000 and Heavy Duty Polymer granulators.
This unique triple-ply laminate has a thin elastomeric membrane between two sheets of steel, identical to what is used in firewalls of some luxury automobiles. It dramatically reduces noise transmitted through the hopper walls and out the feed opening by dampening the sharp, metallic ringing noise caused by material hitting the inside walls. Double wall designs offer little noise reduction when compared to our triple-ply design.
