Maintain System Performance

Cutter and granulator performance is a key element in overall system performance. In order to keep your trim and matrix removal systems working efficiently, and to extend the life of your blades, the knives must be sharpened and the cutter/granulator parts must be serviced on a regular basis.

When you send your PAC cutter or granulator to us for maintenance, we perform a meticulous 8-step inspection. PAC technicians, backed by our engineering staff, have the expertise to diagnose wear issues. Only certified parts and coatings are used to return your equipment to its original cutting tolerance and performance specifications. You will be notified of any necessary parts replacement and additional costs before we proceed.

Please follow packing and shipping instructions below, and be sure to include your contact information (company name, address, phone number) with your cutter.

Knowing that your company’s time is money, Precision AirConvey has made cutter/granulator maintenance incredibly convenient.

  1. Remove and retain motor. (This step is not required, but it will save you money on shipping costs.)
  2. Place covers on the inlet and outlet of the cutting chamber as supplied with the cutter.
  3. Use original carton and plywood base for packaging. If original packaging is not available, bolt the 4 isolators to a plywood base or crate.
  4. Packaging must be securely attached to a pallet or crate for freight shipments. Bolts through the plywood are recommended.
  5. Be sure to include your contact information (company name, email address, physical address, phone number) with your cutter - a business card will suffice.
  6. Please note, we do not use an RMA system.

Model 78 cutters can be shipped via UPS or FedEx.

Model 811 cutters must be shipped via freight carrier due to weight restrictions.

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.
