Industrial Wood Biomass Pellet Mill Machine MZHL508
Wood biomass pellet mill is a new energy equipment for wood biomass, which is a pelletizing equipment for the production of wood pellets.The wood biomass pellete mill is designed for processing various kinds of solid wood materials such as furniture wood waste ,branch ,wood sawdust ,wood shaving etc .The material is crushed and then pressed by pellet machine becoming into high density pellet . Wood pellets are the most commonly used fuel in pellet furnaces.

How to work of Wood Biomass Pellet Mill Machine MZHL508
The material in the granulation bin is fed into the chute by the feeding auger, the material enters the pressing chamber through the forced feeder, and is fed into the two pressing areas in the ring die by the feeding scraper. Due to the high-speed rotation of the ring die The material is brought between the ring die and the pressure roller. Under the strong extrusion action of the ring die and the pressure roller, the material is gradually compacted and formed in the die hole. Because the extrusion of the material between the die rollers is continuous , so the formed material is continuously discharged from the die hole in a columnar shape, and then cut into particles of the required length by the cutter, and then enters the next process.
The compression ratio of Wood Biomass Pellet Mill Machine MZHL508
(Compression Ratio= L/D L: Effective Die Hole Pelleting Length; D: Effective Die Hole Dia)
Generally speaking, the higher the compression ratio, the denser the finished pellets. But it does not mean that the higher the compression ratio, the better the pellet quality. Compression ratio should be calculated based on your raw material for making pellets. Commonly compression ratio is inversely proportion to the hardness of raw material, the harder the raw material, the smaller the compression ratio.
