Common Causes of Malfunctions in Wood Pellet Machines

Wood pellet machines are essential for the biomass industry, but they can encounter various malfunctions. One of the primary reasons for breakdowns is the wear and tear of the bearings, especially in the press rollers . This can be due to the high pressure and friction involved in the pelletization process, leading to premature failure if not regularly maintained.

Another common issue is the inconsistency in the raw material's moisture content . Both excessively high and low moisture levels can affect the pellet quality and machine performance, causing clogging or slippage in the press mechanism.

Misalignment of the press rollers and the die is also a frequent cause of malfunctions . This misalignment can lead to uneven pressure distribution, affecting the pellet formation and potentially damaging the machine components.

Lastly, inadequate lubrication can result in increased friction and heat, accelerating the wear of moving parts and causing operational failures .

To mitigate these issues, regular inspections, maintenance, and the use of high-quality raw materials are crucial for the efficient operation of wood pellet machines.
