Biomass Pellet Inclined Screw Conveyor overcomes the inherent contradictions of biomass pellets—good flowability but easy breakage, and low density but large conveying capacity—providing a continuous, stable, and low-breakage mechanized conveying solution for boiler feeding, storage loading, and production line transfer. The commonly used tilt angle is 15°–45°, enabling stable low-level feeding and high-level lifting. The entire machine is sealed to prevent spillage and dust generation. The wear-resistant blades prevent material jamming and tangling, ensuring continuous and smooth conveying. The sturdy support frame can be equipped with casters, making it suitable for various scenarios such as biomass boiler feeding, pelleting production lines, and fuel silo transfer. Flexible deployment, energy-efficient, and durable, it is a standard lifting and conveying equipment in the biomass energy industry.
The core advantages of the Biomass Pellet Inclined Screw Conveyor lie in its high speed, low loss, and compact design. Optimized for the characteristics of biomass pellets, it employs a gentle pushing method with low speed and large pitch, minimizing pellet breakage during conveying and ensuring fuel integrity and calorific value. Its tilt angle can reach over 60°, achieving significant height lifting in extremely limited space, directly connecting low-level storage to high-level boiler silos, greatly saving plant layout space. Simultaneously, the equipment operates stably and reliably, with excellent sealing, enabling continuous and uniform feeding and effective dust control.
The Biomass Pellet Inclined Screw Conveyor mainly consists of a drive unit, screw shaft, conveying tube, inlet, outlet, support frame, and sealing components. The drive motor and reducer provide stable power. The screw blades feature a wear-resistant, thickened design to prevent pellet breakage and entanglement. The inclined tube is a fully sealed structure, effectively preventing spillage and dust. The inlet and outlet are adapted to biomass pellet feeding conditions. The support frame has an adjustable inclination angle and a stable structure. The overall assembly and disassembly are convenient, and operation is reliable, meeting the needs of biomass fuel lifting and conveying.
The Biomass Pellet Inclined Screw Conveyor works based on the rotational propulsion of the screw, achieving stable lifting of materials within the inclined trough. When the motor drives the screw shaft to rotate, the screw blades with a specific pitch generate continuous axial thrust, pushing the biomass pellets falling into the feed inlet upwards along the smooth trough wall. Due to the pellets' own gravity and friction with the trough wall, the material does not rotate at high speed with the screw, but rather slides steadily upwards as if driven by the screw thread, ultimately achieving continuous, low-loss, and closed-loop conveying from low to high.
The Biomass Pellet Inclined Screw Conveyor can be made with different material combinations to achieve the best cost-effectiveness and durability, depending on your working conditions and budget. Our factory produces stainless steel and carbon steel options.
Carbon Steel: Carbon steel is the standard economical material for biomass pellet inclined screw conveyors. Made of thickened carbon steel, it is wear-resistant, durable, has a high load-bearing capacity, and good weldability. It is suitable for conveying ordinary dry, non-corrosive biomass pellets, has low maintenance costs, and is the mainstream choice in the industry.
Stainless steel material: Available in 304 and 316 stainless steel, suitable for biomass conveying scenarios with higher requirements for hygiene, corrosion resistance, and moisture resistance, such as materials prone to mold growth due to moisture, biomass raw materials containing small amounts of acidic or alkaline media, and food-grade biomass pellets. The smooth, non-stick, and rust-resistant surface of stainless steel effectively reduces material residue and contamination. The entire machine is corrosion-resistant, easy to clean, and has a longer service life.
