What's The Best Materials of Biomass Pellet Press Wearing Parts?

First of all, let’s talk about the material of the wearing parts of biomass pellet press. In order to improve the wearing condition and prolong the repair cycle and service life, the quick wearing parts should be made of high wear-resisting and high hardness materials, including metal anti-wearing material and non metal anti-wearing material.

Metal Anti-Resistance Material for Pellet Mill Wearing Parts

pellet die and roller

  • High Carbon Alloy Steel: It is featured with high hardness and good wearing resistance. After the treatment of tempering, carburizing and nitriding, the surface hardness can reach HRC60. The drawback is that it has bad toughness after heat treatment. This material is mainly be used to make quick wearing parts such as sleeve pipe.
  • Stainless Steel: 4Cr13 is one of the common stainless steel with high carbon content, high strength and hardness. After tempering, the surface hardness could reach HRC58. Stainless steel has corrosion resistant, good strength, high hardness, anti-wearing ability and are easy to processing. The only disadvantage is that the price is a little high.

Non Metal Anti-Wearing Material

Ceramic Anti-Wearing Material: The hardness, corrosion resisting and thermostability of anti-wearing ceramic material is several times of common metal. But, the application of ceramic material in pellet making machinery is still in the primary stage.
