We have own ring die factory and technical engineers with 20 year's experience. Each year, we all sell about 4000 spare parts: ring die, roller, roller assemblies to all over the world.
Ring die is very important part of ring die pellet machine in the whole manufacturing process. The quality of ring die not only directly relates with the quality and output of pellets, but also the running state of equipment and maintenance cost. Range of ring die spare parts' Application Applicable for Biomass pellet machine: wood pellet mill, sawdust pellet mill, grass pellet mill, straw pellet mill, crop stalk pellet machine, alfalfa pellet mill etc. Applicable for Fertilizer pellet machine, all kinds of animal/poultry/livestock feed pellet machine too.

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 WEIFENG Company, 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.
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.
