A Series — Slow Speed Plastics Granulators
Minimizes dust and reduces noise.
Direct-drive staggered rotor
Special knife design makes adjustment unnecessary
Easy access for maintenance and cleaning
Slow rotor speed creates less noise and dust
Easily customizable to suit different applications
General Description
The A 18 slow-speed granulators feature a staggered 180 mm diameter rotor in widths from 180 to 430 mm; the A 30 series has a 300 mm diameter rotor in widths from 400 to 800 mm. A geared motor directly drives the rotor. Its low speed reduces the granulator’s noise level and creates less dust while grinding. The A-series’ specially-designed knives can be sharpened easily and don’t require adjustment afterward.
Depending on the application, the A-series granulators can be fitted with a wide variety of sound-absorbing feed hoppers and base frames and a built-in blower system with matching suction bins or bag-filling adapters allowing integration with most types of injection molding machines and robots.
Applications
The A 18 and A 30 slow-speed granulators are mainly used as beside-the-press machines to grind runners and sprues in injection and blow molding processes. The resulting granules are then immediately reintroduced into the production process. The machines can be used for rejected products in the in-line recycling process as well.
The A 30 series’ stronger design allows it to be used for stronger and thicker materials while offering the same advantages of low noise and dust as the smaller A 18 series. They can also be used as low-noise central granulators for small throughput requirements as well.
Specially-profiled Rotor Knife
The curvature of the specially profiled rotor knives ensures a constant cutting radius after re-sharpening thus maintaining the original cutting gap. Awkward knife adjustment is no longer necessary.
Staggered Rotor Blades
The staggered rotor blades create an individual blade cut thus increasing the cutting torque making the A-series granulators suitable for grinding more solid materials and thicker-walled sprues.

Quick Snap Fastening System
The quick snap fastening system allows the granulators to be opened for cleaning and maintenance quickly without the need for special tools.
