As a critical part of a pellet feed mill, the ring die is not only directly related to pellet quality, but also to the maintenance cost of a feed mill. According to statistics, the cost of wear and tear of ring dies usually counts for 25% of the plant’s total maintenance expenses.

The article Correct usage and maintainance of a ring die
by Mr. Wang Chao, Muyang Group is an interesting for the feed manufacturing practices. the author deeply narrate the Roller gap and Die maintenance . I will be highly obliged if the author throws light on the die maintanance for the following points:

sir regarding the installation,we follow the clearance between the die and roller,but the result of our run test is not good,the raw materials mashed clogged on the die.the roller can not press hard so the output of pellet is so little...our die holes diameter is 4 mm. originally the clearance is zero but its okay it can run continuous.we use feeler gauge for measuring clearance.please advise.thank you

The clearance between the die and roller should be very small or the raw materials will generate adamant shell which prevent pellets generation and clog the die holes.
So, just reduce the clearance between ring die and roller and don't touch each other directly.
I hope it can help you.
