Maximizing Wood Pellet Mill Machine Longevity: Identifying Wear Factors

Pellet Mill Machines play a key role in the production of pellets and pellet production, but they also often face wear and tear. Wear on biomass pelletizer machines can stem from a variety of factors, from the characteristics of the raw material to the setting of operating parameters to maintenance and lubrication practices. An in-depth analysis of the causes of wear is essential to ensure the efficient operation of wood pellet makers. This not only helps wood pellet plants to increase productivity and reduce costs, but also improves the quality and sustainability of the final product. This article will take an in-depth look at the various factors that contribute to wear and tear in wood pellet making machines to help readers better understand the issue so that they can take appropriate measures to mitigate wear and improve wood pellet equipment performance.

What Causes Wear and Tear on Wood Pellet Mill Machine?

Wood pellet mill is the key equipment for biomass pellet production, and like any mechanical equipment, wood pellet mills experience wear and tear and failures that reduce their performance and life span. Although wear and tear of wood pellet mill equipment is unavoidable, understanding the main causes of wear and tear helps us to take proper preventive measures to extend the life of the equipment. Here are some common causes of wear and tear of wood pellet press machines.

Impact of Raw Material Properties on Wood Pellet Mill Machine

Differences in the physical and chemical properties of biomass raw materials have an impact on the wear and tear of the biomass pelletizer machine. Therefore, both the physical and chemical properties of the pellet raw material will be analyzed. (Read more about Property of Common Wood Material>>

  • Influence of Physical Properties of Pellet Raw Materials on Biomass Pellet Maker Mill

From the physical point of view, raw material hardness and moisture content are the two main reasons affecting biomass pellet maker machine wear. High hardness raw materials in contact with the internal parts of the wood pellet maker machine will produce greater friction, thus accelerating the wear of parts. Too high or too low moisture content of the raw material will lead to more wear and tear. Research has proved that equipment wear is minimized when the moisture content of the raw material is 12%-13%.

  •   Raw material with too high moisture content:
  • Wood pellet mill needs to consume more energy to evaporate water during wood pellet processing.
  • Increased viscosity of the raw material makes the wood pellet machine maker more prone to clogging and abrasion.
  • Excessive moisture reduces the lubrication effect between particles and machine parts, increasing friction.
  • High humidity raw material is easy to make the wood chip pellet machine parts damp, triggering corrosion and rust.
  •   Raw material with too low moisture content:
  • Low humidity raw materials make it difficult to form pellets, requiring the wood pellet processing mill to use more squeezing pressure.
  • Low humidity causes temperatures to rise during processing, which can damage the molds and rollers of the making wood pellets machine.
  • The raw material with low humidity is too fragile, which makes it easy to break and form dust during processing, and increases the wear and tear of machine parts.
  • Influence of the Chemical Properties of The Pellet Feedstock on The Pellet Mill Machine

In terms of chemical effects, the sulfur, chlorine, potassium, and sodium pairs present in the raw material have the potential to corrode the biomass pellet mill. Therefore, the chemical composition present in the raw material also determines that wear and tear of the wood pellet press equipment  is inevitably.

Impact of Structure and Design on Wood Pellet Production Machine

Ring Die Pellet Mill Structure Design & Flat Die Pellet Mill Structure Design

The structure and design of a wood pellet processor plays a key role in its wear and tear. Unreasonable structural design of wood pelletizer mill equipment may cause certain parts to be subjected to excessive pressure and friction, thus aggravating wear. For example, key parts in wood pellet mill equipment should have reasonable support and cushioning devices to reduce wear caused by friction and vibration. Therefore, novices should take the initiative to ask the wood pellet machine manufacturer about the relevant parameters of the wood making machine or request a pdf of the structure of the wood pellet maker machine for selection before purchasing the biomass pellet mill machine.

Impact of Operational Parameters on Wood Pellet Making Machine

In wood pellet production, operating parameters such as temperature, pressure and speed influence the biomass pelletizing machine. During the manufacturing process of wood pellets, the internal parts of the wood pellet machinery may become softer or wear out faster due to high temperatures. Temperatures during the molding process of wood pellets can also affect the quality and wear of the pellets. High pressure puts more force on the internal parts of the pelletizer mill, bringing about wear and tear. Excessively high or low speeds may cause wear. Too high a speed may lead to increased friction and wear between parts. ​However, too low a speed may result in poor pellet quality and reduced productivity.

Impact of Operation and Maintenance on Wood Pellet Press Machine

Maintenance of Biomass Pellet Mill for Sale

Improper operation and poor maintenance are also major causes of wear and tear on commercial wood pellet mills. Improper operation such as excessive feeding, unreasonable working temperature, frequent starting and stopping can accelerate the wear and tear of industrial wood pellet mill. In addition, the importance of regular maintenance should not be ignored. Timely lubrication, tightening bolts, replacing badly worn parts, etc. can effectively reduce the degree of wear and tear of the biomass pelletizer equipment.

How wear and tear on pelletizer machines affects wood pellet plant profitability? There are various reasons for pellet mill wear and tear, and we have only listed some of them.
