FAQ from customers who buy pellet mill for wood

pellet mill for wood

(1) How to make the mold life longer?

With the continuous introduction of pellet mill for wood into the market, the development of mechanical tools is also constantly changing. The wear and tear of the mold during the production of wood pellets is also a major cost. So, how to maintain it directly affects the service life of the pellet mill for wood.

Therefore, it also directly affects the processing cost of wood pellets. How to make the mold life of the wood pellet mill machine longer? Get your answer today! (Related post: wood pellet mill for sale)

① Regularly clean oil and fill

If the pellet mill for wood is not used for a month, it is recommended to clean the oil inside, so the oil will gradually harden during long-term storage, which will make it difficult to remove the next time it is used, which will seriously affect the subsequent use of the mold of pellet mill for wood.

After the pellets are processed, it is necessary to use oil to grind for a period of time to ensure that all the oil remains in the die hole, which is of great benefit to the work the next day and is also conducive to the long-term use of the die. The oil can be mixed with waste engine oil and wood chips. It can be made once and can be recycled.

②No need to clean the mold for a long time

If the mold and pinch rollers are no longer used for a long time, it is recommended to remove the mold after cleaning and storage. The master cleans the sawdust pellets inside the mould and adheres to the mould surface. In this way, on the one hand, we can prevent the enterprise from being difficult to remove the pellets due to the hardening of the pellets due to the long-term storage of the students.

On the other hand, because the sawdust has water absorption, if the sawdust on the surface is not removed, it may accelerate the development of the corrosion of the mold surface.

③The mold should be stored in a dry and ventilated place

 Most of the molds of the pellet mill for wood are made of alloy steel. If they are in a humid place for a long time, the surface of the mold may be damaged due to air corrosion, thus greatly reducing its service life.

④The handling process should be careful

The mold of the pellet mill for wood is a high-precision part, and the mold hole is carefully processed according to the compression ratio of the mold. If you are careless during the handling process, the structure of the inner wall of the mold hole is damaged, which may lead to molding during processing. low rate and short service life.

The above are the tips on how to make the mold life longer for pellet mill for wood. Follow these five methods to maintain the mold, and I believe your mold will last longer.

(2) Why do the pellets produced by the pellet mill for wood have a bad appearance?

pellet mill for wood

Why do the pellets produced by the pellet mill for wood look bad? Today we will find out why. During the production of wood pellet fuel by the pellet mill for wood, there will be a situation where the pellets contain powder and have a rough surface. At this time, it is also necessary to check the equipment data settings of the pellet mill for wood. Besides, what is the reason for this phenomenon?

Wood pellets cause more wood pellet powders, this feedstock can be caused by low moisture content, the moisture content of wood pellet machine feed is usually between 12% and ~15%. After adjusting the moisture content of the raw material, the problem still exists, that is, the pressure roller die is seriously worn.

When the inner surface of the ring die of the pellet mill for wood is severely worn or the particle diameter needs to be changed, it needs to be replaced. The surface of the sawdust pellets is rough, which may be caused by the excessive moisture content of the raw material, or the initial use of the mold. This problem can be solved by adjusting the moisture content of the raw material, or by repeatedly grinding the mold with the material.

To sum up, the reasons why the pellets produced by the pellet mill for wood are not good in appearance are mentioned today. I hope it will help you when you use the wood pellet machine again.

Over the years, Richi Machinery has focused on the research and development and production of wood pellet mill machines, biomass pellet machines, sawdust pellet machines, fuel pellet machines, wood processing equipment, drying equipment, cooling equipment and packaging equipment.

(3) Recommended pellet mill for wood

There are many pellet mill for wood on the market. Today, Richi Machinery will recommend some of them:

①The first type of small pellet mill for wood

It is a new type of biomass energy machinery independently developed by our company’s technical staff and has independent intellectual property rights. The pellet mill for wood is simple in structure, easy to operate, stable in operation, and can work continuously. The pressed pellets have the advantages of high density, high combustion value, low moisture and low ash content.

The wood pellet mill machine gearbox adopts high-precision gear transmission, four sets of gears are connected, and the hydraulic oil delivery system can automatically circulate oil between the gearbox and the main shaft bearing. The service life of the main shaft and gearbox gears.

The working parts of the pellet mill for wood (die plate, pressure roller) are made of alloy steel, and the hardness after heat treatment can reach more than 50, which ensures the continuous operation of the machine and prolongs the service life of the whole pellet mill for wood. The electronic control system of the main engine adopts the international standard configuration of star-delta starting, and the operation is extremely stable.

②The second type of small pellet mill for wood

Mainly suitable for granulation of crude fibers, such as corn stalks, sawdust, rice husks, cotton stalks, cottonseed husks, weeds and other crop stalks and factory wastes. It is suitable for low temperature granulation of biological bacterial fertilizer, organic fertilizer and compound fertilizer.

Features of this pellet mill for wood:

①The pressure rollers are evenly distributed, and the operation is stable. At the same time, the pressing area is increased, and the production efficiency is improved. (Related post: biomass wood pellet plant in Indonesia)

②The screw center pressure regulating structure is adopted, and the wood pellet mill mold gap can be large or small, which is suitable for different materials to ensure the pressing effect.

③This model is equipped with Φ6-Φ10mm diameter molds, which are suitable for granulation of different materials and achieve the best benefit.
