Compression Ratio of Ring Die
The ring die compression ratio refers to the ratio of the effective length of the ring die hole to the minimum diameter of the ring die hole. It is an index reflecting the extrusion strength of pellet feed. The bigger the compression ratio is, the stronger the pellet feed is. But not mean the higher ratio is ,the better it is .Compression ratio should be calculated based on raw material for making pellets and type of feed.
With many years pellet die manufacturing and research experience o, we provide some general data of ring die's compression ratio for your reference:
Buyers can customize dies with different hole diameter and compression ratio, according to different situation and requirement.
