Pellet Mill Dies, Carbon Or Stainless Steel?

Without a doubt, the most important component of the pellet mill is the die. The design and the condition of the die will decide if you make pellets or just block the die with material. The pellet mill die however is a very over looked component, and not really given the respect it deserves. The die not only dictates if you make any pellets at all, it also effects pellet quality, pellet mill productivity and energy consumption. Therefore when it comes to producing the die, the pellet mill manufacturer has a few questions to answer. The first questions is should they use carbon steel or stainless steel to produce the die? Each has its own benefits, so either can be a suitable choice. Stainless steel has one specific advantage is terms of increased corrosion resistance. Therefore if the pellet mill has not been used for a significant amount of time, a stainless steel die can make it quicker to get going. However stainless has some significant disadvantages to carbon steel. For instance a stainless steel die is more likely to break, and also has a shorter operating life. Therefore generally a carbon steel die is more suitable for the pellet mill, but must be kept in good condition.

It is important to make sure the holes in a carbon steel pellet mill die are cleaned for corrosion. The corrosion will increase the resistance of the hole. Therefore this is usually the factor that leads to pellet mill die blockages. Therefore before you try to produce wood pellets for instance, it is important to run through some low density oily materials to clean the die holes and reduce their resistance to the desired compression.
