Technical Iteration! Shandong Xingye’s Star Model 560 Ring Die Biomass Pellet Mill Gets Full Upgrade
Recently, Shandong Xingye Environmental Equipment Co., Ltd. officially launched the newly upgraded 560 ring die biomass pellet mill. As the factory’s star core model that has served overseas markets for a decade, this upgrade comprehensively solves pain points frequently fed back by global clients, including insufficient output, fast spare part loss and high power consumption. The brand-new 560 ring die biomass pellet mill adopts re-optimized transmission structure, thickened quenched ring die and pressure roller, as well as upgraded energy-saving main motor. Compared with the old version, its comprehensive production efficiency is increased by 22%, the service life of wearing parts is extended by 60%, and the overall energy consumption is reduced by 15%, perfectly matching all kinds of small and medium biomass fuel pellet production lines. As an original manufacturer, Xingye Environmental also completed the supporting upgrade of full set ring die pellet mill wear spare parts, providing one-stop procurement solutions of complete machines and accessories for global buyers.
The core upgrade highlights of the 560 ring die biomass pellet machine this time:
Remodeled overall machine structure
The new 560 ring die biomass pellet mill adopts an integrated stainless steel pelleting chamber. As shown in the real shot of the equipment, the chamber sealing performance is greatly enhanced, the raw material dust leakage is reduced by 80%, and the workshop production environment is cleaner. The thickened cast steel integrated base eliminates vibration during high-speed operation, and the stability of 24-hour non-stop long-term production is significantly improved, which is perfectly suitable for biomass fuel pellet production lines requiring round-the-clock operation.
Comprehensive upgrade of wear-resistant accessory materials
This transformation focuses on ring die pellet mill wear spare parts. The original supporting ring dies and pressure rollers for model 560 all adopt high-chromium alloy steel vacuum quenching technology. Their wear resistance is doubled compared with ordinary carbon steel accessories. For hard-to-process raw materials such as high-fiber straw and hard miscellaneous wood, the replacement cycle of accessories is extended from the original 3 months to more than 5 months, greatly cutting customers’ later operation and maintenance costs.
Energy-saving optimization of power and transmission system
The upgraded model is equipped with a 220KW national standard energy-saving motor, and the transmission loss of high-precision helical gear reducer is reduced, cutting the overall power consumption by 15% under the same output. The transmission box is equipped with an independent circulating cooling oil circuit to avoid overheating shutdown under high-temperature pelleting conditions, supporting stable long-term production in tropical and subtropical overseas countries.
Wider range of applicable raw materials
The internal extrusion channel is optimized to stably process more than ten kinds of agricultural and forestry wastes such as wood sawdust, bamboo powder, straw, palm fiber, rice husk and peanut shell. The finished pellets are compact and smooth with standard calorific value. It has high compatibility whether used as a single independent machine or integrated into a complete biomass fuel pellet production line.
Supporting solutions for biomass fuel pellet production lines
Many overseas clients consult about how to match the 560 ring die biomass pellet mill with a standard biomass fuel pellet production line. Here is a unified explanation: the standard hourly output of the upgraded model 560 is 2-3 tons, suitable for small and medium complete production lines with 2-3 tons hourly output. The front end can be matched with hammer mill, rotary dryer and spiral conveyor, while the back end can be equipped with cooling sieve machine and finished silo.
For clients with capacity expansion plans, a single production line can be equipped with two sets of 560 ring die biomass pellet mills to lift the overall output of the whole biomass fuel pellet production line to 4 tons per hour. Meanwhile, our factory maintains sufficient inventory of ring die pellet mill wear spare parts. Overseas buyers do not need to wait for long customization cycles, and conventional accessories can be arranged for sea shipment within 7 working days.
The manufacturing and quality control capabilities of Xingye Factory
As a professional original pellet mill factory based in Shandong, Xingye Environmental has 10 years of R&D and manufacturing experience in biomass pelleting equipment. All 560 ring die biomass pellet mills are independently processed by CNC machine tools without third-party OEM. Every unit will undergo a 12-hour continuous feeding load test before delivery, strictly testing four core indicators including motor temperature rise, transmission noise, pellet forming rate and accessory wear resistance. Only qualified machines can be packaged for export.
The factory sets up an independent wear-resistant accessory workshop specializing in mass production of ring die pellet mill wear spare parts. The whole process including raw material forging, heat treatment and precision drilling is completed independently, ensuring synchronous supply of accessories for mass global orders. At present, pre-orders of the upgraded model 560 have been received from multiple countries in Southeast Asia, Africa and Europe, gaining excellent feedback from overseas markets.

The newly upgraded 8th-generation 560 ring die biomass pellet mill is a core product iteratively optimized by Xingye Environmental to meet the demands of the global biomass energy market. It achieves remarkable upgrades in three core dimensions: output, energy consumption and accessory durability. It can produce fuel pellets independently as a single machine, and also be flexibly integrated into all kinds of biomass fuel pellet production lines. Meanwhile, the factory directly supplies full set ring die pellet mill wear spare parts, one-stop solving all clients’ demands for complete machine procurement and later accessory replacement. For overseas merchants planning to invest in biomass fuel processing plants, the new 560 ring die biomass pellet mill is a cost-effective core equipment balancing investment cost and long-term production benefits.
