Compression Ratio

What is the compression ratio of ring die?
The compression ratio of the ring die is the ratio of the effective working length of the ring die hole and the diameter of the die hole. It is an index reflecting the extrusion strength of the pellet feed. The larger the compression ratio is, the stronger the extruded pellets are, but the output will be relatively lower. The smaller the compression ratio, the rougher the surface of the pellet will be and the bad forming will be, but the output will be high.

How to choose the right compression ratio?
Due to different formulations, raw materials, and granulation processes, the selection of an appropriate compression ratio depends on the situation. The following is a general range based on experience:
Livestock and poultry feeds: 1:8 to 13; Fish feeds: 1:11  to 16;
Shrimp feeds: 1:16 to 25; Heat-sensitive feeds: 1: 7 to 9; Forage and straw feeds: 1: 5 to 7.
After using a ring die, the feed producer can also adjust the aperture and compression ratio of the next ring die according to the external feeling of the feed.
