As is known to all, ring die is the core of the pellet mill, while compression ratio is the core of the ring die, which plays an extremely important role in pellet mill industry. Compression ratio affects not only the form of the pellet, but also the lifespan of ring die.
Compression ratio is affected by many factors, mainly forcing on the content of raw material used to produce the pellet. For example, if the raw material owns higher per cent of fiber, and lower per cent of oil, we will choose a lower compression ratio, and vice versa.
From the calculation way of the ring die compression ratio, we could know that if the compression ratio is low, pellet raw material suffers less pressure, and passes the channel more easily. According to this, the production will be higher, and electric power consumption will be lower, which causes some problems like unshaped and various-length pellet.
Meanwhile, if the compression ratio is high, pellet raw material suffers more pressure, and pass the channel more difficult. According to this, the production will be lower, and electric power consumption will be higher, which causes the problems like tough pellet. If the compression ratio is much higher than the used one, it will cause the block of ring die.
Based on all these factors, it is important to choose a suitable compression ratio for ring die to guarantee the pellet performance. You can find out the suitable compression ratio by using ring die with different compression ratio.
If you have no idea about the compression ratio and don’t want to test with ring dies, you can share us your approximate pellet material content. Our engineer can help you to find out the one which can match your demand greatly.
