What are the consequences of using inferior abrasives in wood pellet machines?

Using inferior molds will shorten the service life of the wood pellet machine. There are many reasons for the poor cost performance:

1. Rough equipment in the processing and production of inferior molds: At present, most general mold manufacturers use old lathes for mold finishing. The equipment is relatively old and the processing accuracy does not meet the requirements. In addition, the mold production itself is a copy, and it is difficult to ensure the accuracy of the main matching surface accuracy and processing dimensions. For example, the joint surface between the mold and the clamp, as long as there are a dozen wires of error during processing, the clamp will not hold the mold tightly, causing the wood pellet machine to shake and rub during high-speed operation, resulting in damage to the clamp and the hollow shaft transmission wheel at the same time, and the body vibration. The processing technology of the mold hole of the wood pellet machine mold is very particular. It has the advantages of a neat arrangement of mold holes and smooth hole walls like mirrors. However, the processing of the mold holes of inferior molds is mostly done manually with a small drilling machine. The inner wall of the hole is rough and has ribs. The compression ratio of the mold varies in depth, which makes it difficult to discharge the material from the mold, and it is easy to block the mold and the machine. This increases the power consumption, reduces the production capacity, makes the pellets look rough, and the finished products are uneven in length. Especially when the machine is blocked, the temperature in the mold extrusion cavity rises quickly, which can easily burn the roller bearings and the main shaft bearings, increase the workload, and accelerate the wear of the large and small gears of the wood chip pellet machine.

2. Inferior molds pursue low sales prices: Therefore, there are certain limitations in the selection of billets. It is impossible to select high-quality materials. Only inferior and low-priced billets can be selected as raw materials. The molecular structure of this billet is not strict, the toughness does not meet the requirements, and the wear resistance is poor. The mold made of this billet has a short service life and is prone to cracking. If such a mold is selected, it will not only waste the capital investment of the enterprise due to frequent mold replacement but more seriously, there are also production safety hazards.

3. Because most of the inferior mold processing is imitation: its processing accuracy cannot be controlled, and the errors in various aspects accumulate. If such molds are used for a long time, it will definitely seriously affect the normal operation of the wood chip pellet machine, and the purpose of safety, high yield and low consumption of the wood chip pellet machine cannot be achieved at all. A careful calculation shows that although the purchase price of inferior molds is lower at present if they often fail, parts and bearings are often replaced, the output is reduced, the power consumption is increased, and manpower is wasted, the economic benefits of the enterprise will be affected. In order to make your wood chip pellet machine achieve the purpose of high product quality, high output, low power consumption, and production safety in the process of fuel pellet production, give full play to the working efficiency of the wood chip pellet machine.

4. The mold quenching process is an important part of mold manufacturing: the mold quenching process is very particular, and all use American vacuum quenching furnaces and Japanese multi-purpose quenching furnaces. At present, it is difficult for small mold manufacturers to have this advanced equipment. Generally, they still use the traditional pit furnace quenching. This equipment cannot automatically control the temperature of mold quenching, resulting in inconsistent hardness inside and outside the mold after quenching, and a large deformation coefficient. The mold is easy to lose roundness. When the wood chip pellet machine using this mold is in operation, the pressure roller will frequently hit the mold, which will increase the vibration and noise of the wood chip pellet machine. It is also an important factor in the damage to the main shaft and the hollow shaft. Once the bearings of the main shaft and the hollow shaft are damaged or the inner and outer rings are running, the main shaft and the hollow shaft may be scrapped. If the bearing hole of the main engine box is worn, it will not only cause the wood chip pellet machine to work weakly and the output will be significantly reduced, but also cause the wood chip pellet machine to not work normally.
