High-Performance Pellet Machine
WOOD PELLET MILL
WORKING PRINCIPLE & APPLICATIONS
Wood pellet mills transform wood and wood-based waste into dense, uniform pellets, widely used for heating, power generation, and other biomass energy applications. They provide an efficient, clean, and environmentally friendly energy solution.
Working Principle
Crushed raw materials are fed into the wood pellet machine, where they are compressed by the ring die and rollers into dense, uniform pellets. This efficiently converts loose biomass into high-density pellets.
Where can it be applied?
Heating Fuel
Produces clean-burning pellets for heating, offering an eco-friendly alternative to coal.
Biomass Power Generation
Pellets can generate heat for electricity production in biomass power plants.
Animal Bedding
Highly absorbent pellets help reduce odor, ideal for animal bedding.
Organic Fertilizer
Can be mixed with crop residues and manure for organic fertilizer production.
