Why do pellet mill dies wear out?
Pellet mill dies operate under heavy loads and are constantly subjected to mechanical and thermal stress.
The main causes of wear include:
-
Abrasive wear — hard particles in the raw material and foreign inclusions gradually erode the walls of the die holes and working surface.
-
Impact loads — uneven loading and mechanical shocks cause microcracks in the die.
-
Thermal aging — constant temperature fluctuations lead to loss of metal strength over time.
-
Chemical exposure — aggressive components in the feedstock may cause corrosion of the die material.
How to tell if your pellet mill die needs repair
Signs indicating that die restoration is required:
-
Reduced output — the pellet mill produces fewer pellets or the process slows down.
-
Inconsistent pellet shape and size — pellets become irregular or uneven.
-
Increased energy consumption
-
Visible damage — cracks, burrs, or deformations on the working surface of the die.
-
Increased wear of the pellet mill rollers due to improper die operation.
If you notice even one of these symptoms — don't delay the repair! Timely refurbishment saves you money and extends the service life of your equipment.
