Many overseas buyers face unstable output, frequent faults or downgraded parts when buying wood pellet machines.
Here are six key selection tips to avoid risks and choose cost effective machine.
Output Gap Between Actual and Standard Data
Pellet Machine standard output is tested in ideal conditions.
The raw material moisture is 15 percent with uniform particle size.
Raw material moisture rising 2 to 3 percent will cause over 10 percent output drop.
Buyers shall confirm output data of different materials and reserve 10 to 15 percent capacity margin.
How to Judge Ring Die and Press Roller Quality
High quality ring die uses alloy steel with deep heat treatment.
It has high hardness and deep wear resistant layer. Good press roller wears evenly without partial peeling.
Buyers need to confirm material grade and heat treatment process.
Difference Between Low End and High Quality Pellet Machines
The core difference lies in internal accessories and processing technology.
High quality machines use integral forging main shaft heavy duty reducer and first line electric parts.
The base eliminates internal stress. These designs reduce machine vibration failure rate and later maintenance cost.
