SM Series Granulators

The SM Series of granulators should be considered an all-round granulator.  Designed for general size reduction applications for such materials as start-up lumps, massive purgings, large profiles, voluminous hollow parts and general, thick-walled, plastic scrap.

The SM Series rotor and stator knives are arranged counter angle to each other to produce a true scissor cutting action.  The result is a cleaner, more uniform granulate with minimal heat build-up and minimal energy consumption and sound output.

As knife adjustment is set outside the granulator, knife changes are safer and can be completed up to 60% quicker than adjusting knives inside the granulator. The adjustable SM knife mechanism sets the proper clearance between rotor blade and screen reducing friction and thermal stress on the process material.

A key component on any granulator are the bearings and the SM features solid steel (not cast) bearing housings, which offer more reliable service (eliminating the risk of housing fracture or breaking under heavy shock loads). The solid steel housings are offset to prevent dust, fines and/or granulate from fouling bearing (a common issue on granulators with flange mounted bearings), which in turn provides quieter and cooler operation.

As well as operational efficiency the SM Series have been designed for reduced service and simple maintenance.  Improved rotor designs eliminating the risk of rotor knives lifting or becoming loose during heavy shock loads and straight sharpened knives which require no special sharpening assemblies.

The SM rotor knife bolts are attach to a removable threaded clamp meaning no unnecessary drilling and tapping to repair stripped rotor flight threads and for extremely high impact, abrasive, applications the fully welded, easy access, ‘clam shell’ housing can be equipped with replaceable wear plates.

  • Versatile, processing a comprehensive range of materials.
  • High material throughput.
  • Space saving, compact design.
  • Optimized cutting arrangement, for efficient energy consumption.
  • Low noise level, from double-cross cutting knife configuration
  • Easy maintenance and cleaning, with ‘clam shell’ opening.
  • Minimised service down time, external adjustment jig for pre-adjusted knife arrangement.
