a reclaimer screw for the pulp and paper industry

Short Description:

Reclaimer Screw Shaft is the core heavy-duty component for ash silo reclaimers and bulk solid reclaiming systems. Specially designed for continuous scraping, stirring and conveying of compacted fly ash, dry powder and granular materials, this robust screw shaft solves material bridging, compaction and dead zone accumulation. Featuring high hardness, anti-wear performance and strong torque resistance, it ensures stable, uniform and efficient material reclaiming for power plant ash silos and industrial bulk storage systems.

Detailed Product Overview

Reclaimer Screw Shaft is a customized heavy-duty spiral shaft exclusively matched with silo reclaimer equipment. Different from ordinary conveyor screw shafts, it adopts an optimized wide-pitch spiral structure and thickened integrated shaft body, focusing on breaking compacted dry ash and stagnant materials while completing quantitative conveying. The integral forging shaft body eliminates shaft bending and deformation under long-term heavy-load and torsion working conditions.

All screw shafts undergo overall quenching and hardening treatment, with wear-resistant surfacing welding on spiral blade surfaces to resist long-term scouring and friction of fly ash and fine powder. The precision machined shaft head and spline structure ensure perfect matching with reclaimer drive devices, realizing stable torque transmission and low-noise operation. It effectively solves common silo problems such as material hardening, uneven discharging and silo blockage, supporting 24-hour continuous automatic reclaiming operation.

Core Product Advantages

Heavy-duty Torsion Resistance: Integral thickened shaft body and optimized structural design withstand strong torque and heavy load, no bending or fracture during long-term operation.
Superior Wear Resistance: Overall heat treatment + blade wear-resistant welding process greatly extends service life, adapting to long-term dry ash abrasion.
Anti-blocking & Stirring Function: Professional wide-pitch spiral design breaks compacted ash layers, eliminates bridging and dead zones, ensuring uniform silo discharging.
Stable Torque Transmission: Precision spline and shaft head machining ensures high matching accuracy with driving equipment, stable operation and low vibration.
Customized & High Adaptability: Customizable length, diameter, spiral pitch and blade thickness to fit different sizes of ash silo reclaimers and conveying systems.
Low Maintenance & High Stability: Integrated solid structure with low failure rate, reducing frequent replacement and downtime maintenance costs.

Application Scope

Mainly applied in thermal power plant ash silo reclaiming systems, large dry ash storage silos, cement powder silos, metallurgical bulk material warehouses and environmental protection dust removal systems. It is the core spare part for fly ash reclaimer machines, responsible for breaking up compacted materials and continuous uniform ash reclaiming and conveying.
