How Long Is The Life Of A Ring Die?

Sep 15, 2024

Unlike flat die pellet machines, ring die pellet machines are designed for large-scale pellet production. Every piece of equipment has its own service life. Ring die pellet machines are no exception. If you look at a ring die pellet machine, there is a silvery metal ring with many deep holes drilled in a regular pattern. This is the ring die. The core of the pellet machine.

How long is the life of a ring die?
In fact, pellet mills on the market have different qualities, and so do ring dies. In addition, the different materials pressed by the pellet machine also have a great impact on the service life of the ring die. Generally speaking, the life of a ring die for making hardwood pellets is shorter than that for making straw pellets. Because, in essence, the ring die is a consumable part, and harder materials are prone to strong wear.

The service life of a ring die is not measured by the actual working time, but by the amount of raw materials that the pellet mill can process. Generally speaking, a normal-quality ring die can withstand 3,000 tons of raw materials. A better ring die can press more than 5,000 tons or even more than 7,000 tons of raw materials.

How to extend the service life of a ring die?

In addition to the quality of the ring dies itself, the length of the ring die's service life is also affected by factors such as raw materials, usage performance, and maintenance habits. That is to say, you can extend the service life of the ring die by carefully following the following tips:

After the pellet machine stops working each shift, remove the raw materials left in the hole. Otherwise, when the residual heat is transferred to the raw materials, these materials will harden. In the worst case, it will cause the ring die to crack.

For unused ring dies, should be kept away from the workplace or humid environment to avoid corrosion.

For raw materials that need to be resized, adjust them to a stable and uniform size. This helps prevent the material from causing internal damage.

The gap between the roller and the ring die has a great influence on the efficiency of the pellet machine and the service life of the equipment. Maintain a gap between 0.1mm and 0.3 mm. Although this is a rule of thumb, you still need to pay attention to and adjust it in actual production.

If necessary, install a magnetic device so that the metal particles can be separated before the raw materials enter the pressing.
