How To Avoid Obstruction Of Ring Die Hole Of Pellet Maker


When using a ring die pellet maker to compress timber pellets, we usually encounter the phenomenon of clog of the ring die holes. When the mold hole is clogged, not only is the time required to disassemble and also clean the mold and mildew, but also the manufacturing performance is influenced by the lack of ability to produce fragments after the mold is blocked.

Exactly how to avoid blockage of ring die hole of pellet maker? In today's write-up, we will analyze some of the most common reasons and also just how to solve the issue after the pellet machine mold is obstructed.

Just how to stay clear of obstruction of ring die opening of pellet machine

1. The pellet machine mold and mildew needs to be brightened. The root cause of the clog of the new ring die is different from that of the old one. Some brand-new mold and mildews will have flaws in the mold opening throughout the boring procedure.

The inner surface area of the hole might show up smooth. Nonetheless, usually the exploration process likewise generates tiny scrapes. Also these tiny scratches will certainly generate sufficient resistance during the manufacture of fragments, leading to mold and mildew.

Head blocked. Keep in mind that if the rollers of the pellet equipment can not produce adequate force to get over the resistance of the die openings, it will trigger clog. Generally use a relatively loosened biomass product (I like to make use of wheat bran), about 10-15% vegetable oil as well as regarding 1-2% fine sand.

You mix this product extensively, and afterwards gradually and also repeatedly process it in a pellet machine. This polishing product will certainly aid clean the surface area of the mold hole and also eliminate deterioration.

Expert tip: Usage much less polishing materials. If official website of use is expensive, the surface of the mold and mildew as well as the stress roller will certainly be used, therefore shortening its life span. When the material overview on the mold and mildew is worn out, the compression proportion on the mold and mildew will certainly not appropriate for creating premium pellets.

2. Raw material granularity. See to it that the fragment dimension of the raw product is smaller than the diameter of the die opening. For example, a ring die with an aperture of 6mm uses a 5mm hammer mill screen to create 6mm wood pellets.

Professional tip: It is likewise needed to ensure that there is no contamination in the raw materials (stone/metal). These will certainly not only create obstruction of the die holes, yet likewise cause serious damages to the pellet equipment itself. This may consist of damages to the gearbox or motor.

3. Raw material dampness. It is extremely crucial to regulate the wetness web content of the raw product when making timber pellets. The ideal dampness material of the raw material is less than 15%. If the dampness content is too expensive, such as 20%+, it will easily create bits when it enters the pellet machine. The mold opening is blocked.

Professional tip: Even if you prepare raw materials with optimal particle dimension and dampness web content, you must additionally think about making use of granular binders. Fragment binders can help the process as well as reduce the opportunity of clogging of the pellet machine die.

4. It is recommended to feed the pellet machine gradually to stay clear of clog of the mold and mildew. When the pellet equipment works, there will be a specific temperature level, when it goes beyond 80 degrees Celsius, the all-natural lignin in the wood will thaw and bind the pellets together.

However, if the raw material of the pellet maker is fed into the mold much faster than the processing rate of the raw material, it is simple to obstruct the mold and mildew before the pellet equipment reaches this operating temperature. You need to make certain that there suffices material before the granulation space, however do not entirely cover them.

Expert pointer: The pellet production process generates warmth, which launches the wetness in the raw product. Loading the pellet maker processing chamber with raw materials stops the escape of wetness (steam). This steam is after that taken in by the inbound raw materials. This indicates that raw materials with wetness more than 15% can trigger die clog. As right here , only feed the pelletizer at a rate that can be processed.

5. If you have completed making wood pellets, include a big amount of vegetable oil to the combination in the last few mins of the operation. This will leave a soft oily material in the mold, which will certainly make it much easier to start making pellets again following time.
