What happens when you don’t service the knives in your cutter or granulator?

Have you been postponing maintenance on the cutter or granulator in your trim or matrix waste removal system in hopes of saving a few bucks or avoiding a delay in production?

Bad idea.

Delaying your knife sharpening and recalibration will end up costing you much more in wasted time, clean-up and repairs.

When the knives get dull, they don't cut as often and as regularly as they should, allowing excessively long lengths of material to remain in your cutter or granulator. Even if you don't need your trim to be a specific length or shape, that extra material can stop production and hurt your equipment in various ways:

  • The strips of long trim can wrap around the rotor and seize up the cutter.
  • The trim can clog up the tubing and halt material uptake at the infeeds, leaving you with a tangled mess at your press or production line.
  • Extra friction inside the granulator can heat up your trim waste. If it melts, it can clog up the screen.
  • Too much trim wears down bearings prematurely, which in turn can lead to wear on critical components.
  • The motor ends up drawing more amps as it works harder to cut the extra material. It can trip the motor overload failsafe on the control panel or cause motor failure.
  • The excess trim can shear the motor sleeves.
  • If the trim is abrasive, it can damage the interior components of the cutter or granulator after prolonged exposure.
  • Long trim pieces that move downstream from the cutter can bridge and clog up your ductwork and cyclone.
  • Extra material in the system can lead to excessive dust, which means frequent filter replacements. Excessive dust can become a safety concern.

In short, dull knives lead to lots of downtime from initial equipment failure, and then the need to clean and repair the system.

Precision AirConvey's Cutting Edge Program is a convenient way to make sure that your cutters and granulators work at peak efficiency — while saving 15% on maintenance. It works like this:

  1. You sign up for the program (sign-up is free!) and send PAC your cutter/granulator.
  2. PAC-certified technicians sharpen and adjust your blades to their original clearance.
  3. The technicians make recommendations about the length of intervals between service, based on the model and knife type, material and system specifications, and knife and component wear.
  4. Your cutter/granulator is returned to you.
  5. You get email reminders when it's time to send your cutter/granulator back to PAC for its next scheduled maintenance.
