Process for making pellet mill ring die:

Blank raw material Forging---Rough turning---Half finished turning---Drilling the hole---Grinding inner bore---Treaded hole--- Keyway milling---Heat treatment---Finish turning---Package. 

Compression ratio of ring die:
Generally speaking, the higher the compression ratio, the denser the finished pellets. But it does not mean that the higher the compression ratio, the better the pellet quality.
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 of our manufacturer, 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.

The most common structure of die hole are straight hole; release stepped hole; external conical hole and internal conical hole, etc. Different die holes structure are suitable for different raw material and feed formula for making pellets.
