Die—The Key Part of Pellet Mill

Machines have key parts which determine machines performance. When it comes to pellet mill, the key part of it is die. Usually there are two types of dies, the flat die and the ring die. Each of them has its individual advantages and disadvantages. Flat die is convenient to be observed during the production process and easily cleaned and replaced. Only being suitable for small-scale pellet production is one of the disadvantages of flat die.

Another disadvantage of flat die is the uneven friction between flat die and roller because of flat die pellet mill working principle which will affect flat die life-span. Regarding the ring die, it is designed for large-scale pellet production. With equal pressing, ring die can last longer and produce quality pellets.

One disadvantage of ring die is that it is not visible to the operators during biomass pellet production because of being encased and it is also heavier. Therefore, for the buyer, you should make decisions according to your capacity requirement. For whichever die, it is always recommended using an oily material to finalize each production. For instance, rapeseed cake is a good material for this purpose and is easily available. Oil material will keep the die holes oily and then they can get rid of pellet mill corrosion. This will make next production start-up much easier and also life span of die can be increased.
