Replaceable lining: The tank body is lined with wear-resistant polymer materials or ceramic patches to extend the maintenance cycle.
Sealed conveying: The fully enclosed structure prevents dust from overflowing, meets environmental protection requirements, and reduces material loss.
Multi-angle installation: supports horizontal, inclined (≤30°) or vertical arrangement to meet the needs of different sites.
The biomass shaftless screw conveyor has a rich selection of materials. The basic model uses carbon steel, which is economical and practical; 304/316L stainless steel can be selected for conveying corrosive materials, which is rust-resistant and durable.
Carbon steel material: economical, practical and high-strength, suitable for conveying low-corrosive biomass materials such as dry wood chips, straw, and rice husks. Its anti-rust ability can be significantly enhanced by spraying anti-corrosion paint or galvanizing, which is the most cost-effective conventional choice.
Stainless steel material: It has excellent corrosion resistance and hygienic standards, especially suitable for high-humidity materials, materials containing salt/corrosive components, and food-grade biomass. Its easy-to-clean and rust-free characteristics ensure long-term stable operation of the equipment.
Wear-resistant steel material: With ultra-high wear resistance, the service life can reach 3-5 times that of ordinary carbon steel, which is an ideal choice for high-wear materials and hard shells. It is usually made of wear-resistant layer surfacing on the edge of the blade or integral wear-resistant steel plate, which greatly reduces maintenance frequency and operating costs.

The biomass shaftless screw conveyor is mainly composed of spiral blades without a central shaft, U-shaped or tubular troughs, drive devices and auxiliary components. The spiral blade adopts an integrated molding process, and the shaftless design avoids winding. The material can be stainless steel or wear-resistant carbon steel, and the surface can be welded with a wear-resistant layer; the trough is a closed structure, lined with polyethylene or cast stone wear-resistant lining to reduce friction loss; the drive device includes a motor, a reducer and a coupling to provide stable power; the auxiliary components include the feed port, the discharge port, the sealing device and the frequency conversion control system. Some models are equipped with anti-blocking sensors. The overall structure is compact, and the various components work together to achieve continuous transportation of biomass materials.
The biomass shaftless screw conveyor rotates in a closed trough or tubular channel through a spiral blade without a central shaft, and uses the blade thrust to continuously push the biomass material. The shaftless design avoids the entanglement of fiber materials such as straw and vines. The large pitch blade is suitable for fluffy or sticky materials. The close fit between the spiral and the trough enhances the pushing force. It can handle various forms of biomass such as straw, wood chips, and energy crops.
Biomass shaftless screw conveyors are used in agricultural waste treatment, forestry processing, energy crop processing and organic solid waste treatment.
Biomass energy field: In biomass power plants, it is used to transport power generation raw materials such as straw and wood chips, as well as transport biomass ash after combustion; in biomass biogas projects, it is responsible for transporting fermentation raw materials and biogas residues and liquids to ensure the continuity of biogas production.
Garbage treatment field: Urban domestic waste contains a large amount of biomass components. Shaftless screw conveyors can be used to transport sorted biomass waste, such as kitchen waste and waste paper, to subsequent processing links to improve waste treatment efficiency.
Industrial production field: In food processing, papermaking and other industries, it is used to transport biomass waste, such as fruit residues in food factories and waste pulp in paper mills, to achieve waste recycling and reuse.
The biomass treatment scenarios are complex and diverse. From farmland straw collection to waste incineration power generation, the material characteristics and transportation requirements vary significantly. The biomass shaftless screw conveyor achieves "one machine for multiple uses" through modular design.
Free combination of length: the conveying length of a single machine can reach 30 meters, and it supports multi-stage series connection to meet the cross-regional operation needs of large-scale garbage treatment plants.
Flexible discharging method: It supports three modes of bottom discharging, end discharging and side discharging, and can be seamlessly connected with crushers, filter presses, boilers and other equipment.
Wide temperature adaptability: Equipped with a special high-temperature resistant lining, it can operate stably under a high temperature environment of 200°C, and is suitable for high-temperature working conditions such as biomass pyrolysis and incineration.
Choose a shaftless screw conveyor for transporting biomass, because the design without a central shaft prevents straw and vine entanglement, is suitable for fluffy/sticky materials, and can effectively cope with the transportation of multi-form biomass such as agricultural and forestry waste.
The choice of a shaftless screw conveyor for transporting biomass is mainly based on its strong anti-entanglement, high conveying efficiency and strong adaptability. These advantages accurately solve the key pain points in the transportation of biomass materials.
Strong anti-entanglement: Biomass materials, such as straw, wood chips, and organic waste, have long fibers, are easy to entangle, and have strong adhesion. Traditional shafted screw conveyors often have the center shaft entangled by the materials, causing blockage, wear, and even shutdown problems. The shaftless screw conveyor eliminates the center shaft design and directly pushes the materials with the integral steel spiral blades, completely eliminating the risk of entanglement.
High conveying efficiency: The biomass processing scene has an urgent need for continuous and large-scale transportation. The shaftless screw conveyor achieves efficient operation through structural optimization. Under the same diameter, its conveying volume is 1.5 times that of traditional models, and the maximum conveying capacity of a single machine is 300 tons/hour.
Superior performance: Biomass material transportation is prone to dust, odor, and spontaneous combustion risks. The shaftless screw conveyor adopts a U-shaped fully enclosed trough and a rainproof cover design to form a triple protection: the silicone sealing strip between the trough and the cover is fastened with bolts to ensure that the dust leakage rate is less than 0.01%, meeting food grade standards.
Strong adaptability: Biomass processing scenarios are complex and diverse, and the shaftless screw conveyor achieves "one machine for multiple uses" through modular design: equipped with a special high-temperature resistant liner, it can operate stably in a high-temperature environment of 200℃, suitable for pyrolysis, incineration and other working conditions.
