how to operate wood pellet mill correctly
In practical work, wood pellet mill always appear some small problems. For example, when in operation, sometimes the pellets have small density, or they are loose or even cannot form pellets. Some other times, the material will block the pressing die holes. Why do these problems happen?
As a matter of fact, to press wood sawdust into pellets, there are 2 preconditions:
- The moisture content of sawdust must reach certain range, which is 8%-12%.
- The pressure of sawdust should reach 50MPA, which means the compression ratio of pressing die hole must be proper. Only with right compression ratio can the wood pellet mill operate normally.
When using the wood pellet mills, remember to carefully read the Instruction Manual first.
Also, there are some tips for correctly operating the wood pellet mills:
- If the wood pellet mill should be operated for long-term, fix it onto a cement base. If the working place is not constant, the wood pellet mill and electric motor should be installed on an angle iron engine base.
- After installing the wood pellet mill, check if all parts are fastened tightly. If there is looseness, tighten it.
- Check the tightness of belt, and if the motor shaft and wood pellet mill shaft are paralleled.
- Before starting the wood pellet mill, first see whether the motor and pellet mill is well lubricated.
- When at work, keep an eye on the operation of wood pellet mill and feed the raw material regularly to prevent blockage. Don’t make the machine operate with overload for long time. If there is vibration, strange noise, temperature raise or material spaying out, stop the machine immediately to check. After trouble clearing, put it into normal operation.
- Before feeding into wood pellet mill, see if there are impurities like copper, iron or stone pieces in the raw material to prevent damage to the machine.
- When feeding raw material manually, stand at the side of wood pellet mill to protect yourself.
