The parts you take off are a record of how the machine has been running. Where the wear sits, and how it looks, points to the cause of the problem.
A worn part is a free diagnostic report.
What each wear pattern tells you
- Jaw plates: wear concentrated on the discharge-opening side. Check the feed for segregation and whether the feeder is loading one side. An even depression across the middle of the plate is normal wear.
- Blow bars: wear on one side only points to a problem with the feed direction or the rotor rotation direction. Cracks mean uncrushable material has entered the chamber.
- Cone liners: local pitting means tramp metal has passed through the chamber. Even thinning around the full circumference is normal wear; a discharge opening kept too small for a long time will accelerate it.
- Screen mesh: broken wires concentrated on the tensioned side. The tension is not high enough, or the support beams are worn.
- Conveyor belts: wear along one edge means the belt is running off track. Ring-shaped wear marks mean an idler has seized.
Recommended practice
Take photos at every replacement. Record the tonnage and the wear location. After three months you have the wear pattern of your own production line.
