Granulator Maintenance

Turns scrap back into feedstock, and does it badly when the knives are dull — producing fines and heat-degraded material that destabilise the process on the press downstream.

Components To Track

ChatterFix builds these as child assets under granulator, so failure history and PM completions attach to the component that actually failed — not just to the machine.

How Granulator Actually Fails

The failure modes worth designing a maintenance schedule around — in rough order of what they cost when they happen.

  • Rotor and bed knife dulling, producing fines and heat instead of clean regrind
  • Knife gap drift after a blade change
  • Screen wear and blinding
  • Bearing failure from plastic dust ingress

What To Measure

Recording that a PM was "done" tells you nothing next quarter. These are the readings that let you see a failure coming — and the reason ChatterFix captures measurements against the asset rather than just completions.

  • Knife sharpness and gap set to OEM spec after every change
  • Fines content in the regrind — the direct quality measure
  • Motor load, which rises as knives dull
  • Screen condition and hole wear

Spares Worth Stocking

The parts whose absence turns a short repair into a long outage.

Common Questions

What maintenance does granulator need?
ChatterFix schedules 2 routines against this asset: granulator blade & screen service (monthly), quarterly drive & gearbox service (quarterly). The readings that matter most are knife sharpness and gap set to oem spec after every change.
How does granulator usually fail?
The most common modes are: rotor and bed knife dulling, producing fines and heat instead of clean regrind; knife gap drift after a blade change; screen wear and blinding; bearing failure from plastic dust ingress. Most of these degrade gradually rather than failing outright, which is what makes interval-based inspection worthwhile.
What spare parts should we stock?
Rotor and bed knives, Screens, Bearings and seals, Knife shims. The test is lead time, not cost: stock the part whose absence turns a two-hour repair into a two-week outage, even if it is cheap.
Can I track this in ChatterFix?
Yes. Pick your industry at signup and granulator is created as an asset with its 3 tracked components, with its PM schedule already attached. Technicians then log readings and findings against it by voice rather than typing them in.

Where It Fits

Get Granulator Into A Real CMMS

ChatterFix builds this asset, its components, and its PM schedule automatically when you pick your industry — then your technicians update it by talking, not typing.
