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.

Ring die hole main type:

WARM TIPS:
How to maintain and inspect the ring die:
1. The rollers should be correctly adjusted, make sure the hole inlets are not damaged by contact with the rollers or as a result of tramp metal.
2. Material should be evenly distributed across the whole working area
3. Make sure that all holes work uniformly, opening the clogged holes if necessary.
4. When changing dies, carefully inspect the condition of the die seating surfaces and fixing systems including collar, clamp or wear ring.
