Vertical Ring Die Wood Pellet Mill
개요
The vertical ring die wood pellet mill, also known as a vertical wood pellet production machine, has its ring die fixed horizontally inside the machine body. The feeding method is that the material falls vertically by its own gravity, which is the main difference between it and the horizontal wood pellet mill.
With its unique top-feed design, this machine is particularly good at processing various lightweight materials, such as wood chips, shavings, sawdust, straw, alfalfa, rice husks, palm fiber and other biomass raw materials.
Richi Machinery offers various models with hourly outputs ranging from 1 to 10 tons. In addition, we can customize integrated solutions to meet specific customer needs based on their actual operating conditions.
Key Advantages
This vertical ring die wood pellet mill adopts a unique vertical ring die structure design. Its core components include the ring die pressure roller assembly, feeding equipment, transmission system, automatic lubrication, feeding and cooling system, and transmission system. The quality of the core components directly determines whether the machine can produce efficiently, save energy, and be durable.

01
Ring Die and Roller Assembly
We use 42CrMo alloy steel to make the ring die and pressure roller, and perform carburizing and quenching treatment to significantly enhance the wear resistance of the parts, making them perform excellently when processing coarse fiber raw materials such as sawdust, wood chips, and palm fiber.

02
기어 구동 시스템
The gearbox delivers powerful extrusion force, enabling the material to pass smoothly through the die holes. The gears undergo precision grinding and hardening treatments, allowing them to withstand heavier loads.

03
지멘스 주동기
Siemens-branded motors provide stable, reliable, and high-quality power support for the equipment, ensuring continuous and efficient large-scale production while significantly optimizing energy consumption and effectively reducing electricity costs.

04
VFD 피더
The variable-frequency speed-controlled feeder enables precise control over the feeding rate, thereby preventing issues such as material clogging and equipment idling. Furthermore, its unique vertical feeding design prevents material bridging, ensuring a uniform and smooth discharge.

05
Lubrication System
A circulating thin oil lubrication system can automatically lubricate transmission components such as gearboxes and bearings, while also removing heat generated during mechanical operation and impurities such as metal abrasive particles, thereby significantly reducing wear and extending equipment life.

06
냉각 시스템
A cooling system can expel the high-temperature, humid air generated during the pelleting process. In addition, the circulating oil lubrication system can significantly reduce bearing temperature and prevent shutdowns due to overheating.

Other Related Wood Pellet mill
We offer not only vertical ring die wood pellet mills but also horizontal wood pellet mills. The horizontal wood pellet machine uses a forced feeder to ensure even material entry into the pelleting zone, guaranteeing continuous and stable production even at high capacities. Below are some of our best-selling wood pellet mill models for your reference.

- A sawdust pellet mill is mainly used to compress fine wood residues such as sawdust, wood shavings, and woodworking waste into dense wood pellets.

- A wood chip pellet machine is designed to process larger wood residues, such as wood chips and forest waste, into uniform biomass pellets. Compared with sawdust, wood chips usually require additional size reduction before pelletizing because of their larger particle size.

- A bamboo pellet machine is specially designed to process bamboo waste and bamboo residues into biomass pellets.
Biomass wood Pellet Mill
- A biomass wood pellet mill is a more general-purpose pelletizing machine designed to process various woody biomass materials into fuel pellets. It is commonly used in complete biomass pellet production lines for commercial and industrial applications.
