ring die_spare parts for pellet mill

The die and rollers are the most wearing parts of the pellet mill, especially for a large biomass pellet production line. The high quality dies and rollers help defining the capacity and economy performance of the industrial pellet plants. By adapting the advanced manufacturing technology around the world, together with the researches of the development department, GEMCO always stand at the front of the industry. Also, GEMCO spare parts for pellet mills can be customized.

Ring Die for Ring Die Pellet Mill

The name “ring die pellet mill” is named after the shape of the pellet mill dies, which is the main part for large pellet mills. As the main wear parts during wood pellet production, pellet mill ring dies must maintain good mechanical properties in order to enhance the serve life.

In some ways, ring die quality determines the productivity and cost of the complete wood pellet plant. A good quality ring die can produce uniformed wood pellet stably, and good quality ring dies surely have longer serve life, which means lower pellet production cost. A bad quality ring die not only has shorter serve life, but also can cause some dangers during pellet production. If the ring die cracks during wood pellet production process, the pellet production must be suspended, and it can also cause the ring die pellet mill breakdown, so the maintenance fee rise.

As a leading pellet plant provider in China, Gemco provides quality ring dies for large scale pellet production, which can help you maintain stable wood pellet production and less maintenance cost.

Gemco pellet mill roller assemble includes pellet mill rollers and roller shells. There is no direct contact between the axle of rollers and the raw materials, so pellet mill roller axle is not the most wearing parts. On the contrary, roller shell contacts with raw materials and ring dies directly, so it can be wore heavily. For pellet plants, with a certain quantity of wood pellet production, the worn roller shells must be replaced, otherwise, it will effect the wood pellet production performance.

Gemco Pellet Mill Roller Shell Types

The basic shape of pellet mill rollers are similar, but the patterns on the surface of roller shells are different, such as corrugated pattern, oblique shaped, honeycomb shaped, etc.

Among all these different types of roller shells, corrugated roller shells are the most popular pellet mill roller shells. Normally, the corrugated roller shells can be divided as open end corrugated roller shell and closed end corrugated roller shell. But closed end corrugated roller shell is mostly used to fish feed pellet mill.
