Wide Application : Transforms agricultural and forestry waste such as sawdust , rice husks , and corn stalks into usable wood pellets or fuel , significantly addressing storage and disposal challenges for such residues. Expanded Feed and Discharge Ports : Features an enlarged 11in feed hopper for easier material loading. Features an 8.4in x 4.3in discharge port to minimize pellet splatter and facilitate collection. High Calorific Value : Powered by a 220V three-phase 7.5KW heavy-duty motor , wood pellets achieve a calorific value of 3000-4300 kcal/kg. Pellet calorific value varies by wood species. Hardwoods yield the highest calorific value due to their dense texture. Pre-lubricated Gearbox : Pre-filled with LCKC150/200# gear oil for immediate use. Users must remove the rubber vent plug before startup to prevent oil leakage and ensure proper gearbox operation. Maintenance Notes : Before operation , adjust the adjustable nuts to balance 2 rollers , preventing machine damage. Lubricate the grinding chamber every 4-6months using high-temperature grease (not included). This practice enhances the wood pellet mill's long-term performance and durability. This wood chipper requires a 220V three-phase power supply with a rated power of 7.5KW. We recommend that you connect it directly to an air switch for use. Under optimal conditions , when processing dry , finely-chopped biomass materials with a moisture content of less than 15% , the output of this equipment is approximately 60kg. The combustion value of the final particle fuel typically ranges from 3000 - 4300 kcal/kg , and the specific value depends on the type of raw materials used , such as sawdust , wood chips , rice husks , or straw , etc. The inner diameter of the feed hopper is 11 in and the outer diameter is 12.2 in. This design ensures that the processed biomass can be smoothly loaded and avoids blockages. The discharge opening measures 8.46 in * 4.33 in , effectively reducing the scattering of particles and facilitating their smooth collection into bins or bags. The gearbox is pre-filled with LCKC150/200# lubricating oil. It is necessary to lubricate the grinding chamber every 4-6 months with high-temperature grease (excluding the grease gun and grease).
