Biomass wood pellets have emerged as the best alternative to oil, coal, and natural gas in light of the growing demand for energy and the deteriorating environment. The wood pelletizer, straw pellet machines, and other biomass sawdust molding equipment are all examples of biomass pellet machinery of the highest quality.
Some of the raw materials that you can use in the production of pellets are as follows:
- Bagasse
- Bamboo
- Leaves
- Palm silk
- Peanut shell
- Rice husk
- Sawdust
- Straw
- Sunflower shell
- Tobacco residue
- other crops containing wood
The Working Mechanism of a Wood Pellet Mill
Flat dies are used in the design of the wood pellet machine. Electric motors, gasoline engines, diesel engines, and PTO are all types of power sources (Power Take Off). Types D and R exist. The "D-type" refers to a rotating die type in which the roller is fixed while a flat die rotates around the main shaft. However, in contrast, the rotating roller pellet mill (R-type) means the roller rotates with the main shaft, and the flat die is fixed, and it is the pro version of the D-type. You can easily control the operation with this device. In order to friction the flat die and roller, the machine uses a gear-driven spindle to drive the spindle. The resulting friction temperature can reach more than 80 °C. The high-quality molding wood pellets will roll out of the discharge port after being extruded through the hole in the flat die at a high temperature. It is possible to control the particle's length with a knife.
Characteristics of a Good Wool Pellet Machine
The gearbox is constructed from high-quality gray cast iron, which has excellent shock absorption and produces very little noise.
It is possible to avoid the drawbacks of belt slipping and a short belt life by using a transmission that makes use of bevel gears. This transmission type is more efficient than worm gear drives and belt drives.
The reinforced shell was increased, and the thickness of castings was increased as well, which resulted in a significant increase in the machine's strength, which put an end to the wood pellet machine. A phenomenon is known as shell fracture.
The flat die and roller both use high-quality alloy steel, and their hardness ranges from 55 to 60 HRC.
The structure of the die hole is best suited for the processing of wood sawdust. The essential technology, which was arrived at after conducting a great deal of research and testing - is the optimal compression ratio of the die hole.
System of electronic control that is both safe and fully compliant with the CE standard for operating systems. In the event of an emergency, the machine can be quickly turned off by pressing the urgent stop button.
Maintaining stringent and standardized production and technology management ensures the consistency and interchangeability of the machines and parts. This allows you to feel more at ease when selecting spare parts for their devices.
Final Thoughts
Choosing a wood pellet machine is not that easy, but you can end up buying the right one if you focus on the right features and characteristics of the equipment. If you have doubts, you can always ask an expert.
