How to maintain pellet mill die and roller
Exactly how to preserve pellet mill die as well as roller?
The roller and die are the using parts in a pellet machine. To utilize and preserve Richi machinery in right way can lower the failing rate, boost the production, elevate the working efficiency, conserve time and labor. If there is any type of issue in the roller and also die, the developing rate and production would certainly decline.

Fill richi pellet with oil combination
Each time after utilizing, or when you intend to change the die, keep in mind to feed oil mix (combined sawdust and waste oil) to the pellet device, squeeze out all the biomass products and fill up the die holes with oil blend.

The biomass materials contains wetness, which would certainly increase the deterioration of the die, and also cause it harsh inside. The oil mixture filled in the die doles will shield them from rusting or deterioration.

Replace the oil mix every half a year
If you have actually leaved the pellet mill die apart for over a fifty percent year. You require to replace the oil combination in the need new, or they would certainly solidify as well as obstruct the holes. This will affect the usage for following time.

Address the block of the pellet mill die
If the die holes are blocked and the wood pellets do not appear, we can use oil soak or preparing to soften the raw materials, and make pellets once more. If this technique does not function, you can make use of drills to extrude the raw products out, as well as feed oil products and fine sand mixture to grind the die.

Location the spare parts in appropriate areas
Preserve the pellet mill dies in ventilate and also dry area. If preserved in wet location, they will certainly rust quickly. If you don't use it for very long time, you can coat it with a layer of waste oil to stop corrosion of dampness airborne. Don't place the pellet mill die where the raw products are kept. The raw products are very easy to take in moistures, which would certainly speed up the corrosion of the die.

Smooth the die and also chamfer the die orifices
The holes on the pellet mill die are processed by high-speed gun drill, which has high level of smoothness. Check if there is any type of bulges externally of the die, if so, smooth them with a flint glazing equipment. If the die orifice are secured or have inversion, you need to chamfer the die orifices and refurbish it.

Adjust the clearance between the roller and also die
In level die pellet maker, the ideal clearance in between roller and also die is 0.1-0.3 mm. If the clearance is as well tiny, the abrasion between the roller and also die will certainly magnify. If the clearance is as well large, the raw materials layer will be thick and also the manufacturing will decline. In ring die pellet equipment, the appropriate clearance is 0.1-0.4 mm.

Keep the pellet mill die and roller tidy
When the wood pellets have benefited thirty days, you need to clean up the roller and die with diesel or fuel. Coat them with lube oil and also mount them again. To guarantee stable high production, we ought to keep the inside of the die tidy.

If the ash is connected to the roller or the lubricating oil is insufficient, the rollers would turn unsteadily, and the manufacturing rate will certainly be affected. Individuals need to examine the functioning condition of rollers regularly.

Pre-heat the pellet device
Whenever before making wood pellets, feed the oil blend repetitively up until the temperature inside depends on 50 ℃. After that you can feed the biomass products to make pellets.


In winter, as the weather is cool, the die is frail, we ought to preheat the device for longer time, so that the pellet maker can work better, the manufacturing is higher, and also the service life is much longer.

Ensures raw materials high quality
During the working of timber pellet maker, you ought to ensure there is no stones or irons in the raw materials, in case they create damages to the die.

The moisture content in the raw products ought to be 10%-18%. Dry material are difficult to mold, which will certainly escalate the abrasion of the pellet device. If the raw products are as well moist, the dampness would evaporate as well as combine with the timber powders, and also obstruct the holes on die.
