Features and Advantages of Vertical Ring Die wood Pellet Mill
Features and Advantages
High production capacity
The vertical ring die design allows the pellet mill to offer high efficiency and production capacity. Vertical ring die pellet mills offer higher throughput than traditional horizontal ring die pellet mills.
Durable and stable
The core components of the machine, such as the ring die and rollers, are made of wear-resistant materials. Regular maintenance ensures long-term stable operation and reduces downtime.
Adaptable
It can handle many types of materials, including wood chips, straw, straw powder, grains, rice husk and so on. The diameter and length of pellets can be adjusted according to different production requirements.
Low maintenance cost
The equipment design is simple and the parts are easy to replace and maintain, so the maintenance cost is low. The mechanical equipment runs stably, reducing the failure rate and downtime of the equipment.

Working Principle of Vertical Ring Die wood Pellet Mill
Working Principle
When the Vertical Ring Die Wood Pellet Mill is working, the material falls into the pelletizing chamber by gravity, and the main shaft drives the pressure roller to rotate at high speed in the stationary ring die. The pressure roller and the ring die produce strong extrusion pressure, so that the material is squeezed into the ring die hole, through the shaping from the ring die hole extrusion into cylindrical particles, and then by the cutter to cut into the required length, and the final shape of the particles discharged from the outlet.
Application Scenarios of Vertical Ring Die wood Pellet Mill
Application Scenarios
Biomass Pellet Production
Used in biomass pellet plants to convert wood chips, straw and other agricultural and forestry waste into biomass pellet fuel.
Animal Feed Processing
Vertical ring die pellet mill can press uniform feed pellets. It is widely used for poultry, livestock and aquatic feed production.
Organic Fertiliser Production
It is used to press organic materials into granular organic fertiliser to improve the efficiency and convenience of fertiliser.
Sludge treatment
n the field of environmental protection and waste recycling, Vertical Ring Die Pellet Mill is used to convert waste into valuable pellets.
Successful Cases of Vertical Ring Die wood Pellet Mill
Successful Cases

A wood processing plant in Germany

An organic fertiliser company in the USA
A vertical ring die wood pellet mill was used to process organic fertiliser. The uniformity and hardness of the pellets have been significantly improved, and production has increased by 20%.

An animal feed production plant in India
A vertical ring die wood pellet mill was introduced to process raw materials such as grains, straw and soya meal into high quality animal feed pellets, increasing output by 25%.
Frequently Asked Questions.
It is suitable for many kinds of biomass raw materials, like common wood chips, straw, rice husk, corn cob, etc. It can also process hay and palm meal.
The humidity is recommended to be controlled at 10% – 18%, if the humidity is too high, the material is easy to caking and clogging the mould, and if it is too low, it will affect the quality of granule moulding. As for the size, the length of the material should not exceed 5cm.
The pellets are well formed, high density, smooth surface and moderate hardness. By virtue of the reasonable pressure roller and ring mould cooperation, the material is tightly combined under high pressure, which can reach the quality standard of biomass fuel, feed and other corresponding industries.
Yes, according to the customer’s requirements for pellet diameter (e.g. 2 – 12 mm) and length, we can change the moulds with different specifications, adjust the parameters and customise the pellets to meet the personalised needs of biomass power generation, special breeding feeds and so on.
Good compatibility, can be seamlessly connected with dryer (adjust raw material humidity), conveyor belt (material transfer), baler (finished product packing), etc. to build a complete production line.
