Product Details

Vertical ring die pellet mill is suitable for pressing materials which are difficult to be bonded and moulded. Such as: rice husk, peanut shells, tree branches, bark, wood chips, straw, coconut shells, coffee shells, eucalyptus, palm silk and other materials. It is a high-density granulation moulding equipment. Widely used in: biomass burning plant, wood processing plant, food factory, fertiliser factory, feed factory, power plant, distillery and other waste gas scraps re-cycling.

The mould and pressure roller are made of alloy steel. Processed by heat treatment. It can ensure the granulation effect. Thus the service life is increased. The working mode is from inside to outside extrusion type. The combination of centrifugal force and extrusion force is utilised. The hardness and density of the pellets can be guaranteed at the same time. It can also increase the pelleting production efficiency. Vertical ring die pellet mill adopts the unique design of 4 pressure rollers. It increases the frequency of extrusion and improves the production capacity.

Technological Process

The mould of the vertical ring die pellet mill is a porous cylinder. It rotates by transmission. There are 2-4 free rotating with grooves in the cylinder. Or slave self-rotating rollers. The biomass raw material enters the steel film. In the rotating roller pressed into the workshop. Inside embedded in the mould holes, the material from the outer base of the steel film. Eventually cut into cylindrical granular form by knives. On the ring die and the pressure roller, the linear velocity is equal everywhere. No additional friction is generated. All the pressure comes from the granulation and therefore the production efficiency is high.

Advantageous

1. Vertical ring die pellet mill has the features of small size, environmental protection and energy saving, low noise, even feeding, compact structure, stable performance and so on.

2. The main transmission box is casting, with larger bearing capacity and good stability. Long service life.

3. The main transmission system adopts gear transmission, which is more efficient. Its capacity is more than 15% higher than belt type.

4. The mould is double-layered and can be used both up and down. It can reduce the production cost, high production and energy saving.

5. Independent discharging device ensures the moulding rate of granule, and the design is reasonable.

6. The main force receiving element adopts high alloy wear-resistant material, and the life span of wearing parts is twice that of similar products.

7. mould view, pressure wheel rotation, material centrifugal, uniform around.
