Shaftless Screw Conveyor

Shaftless Screw Conveyor is a specialized bulk material conveying equipment designed to solve the blocking,winding and jamming problems of traditional shafted screw conveyors.Different from conventional screw conveyors with central shaft and blade structure,this machine adopts an integral thickened spiral blade without central shaft,cooperating with U-shaped trough and wear-resistant lining.It is highly adaptable to wet,sticky,fibrous,clogging and mixed impurity materials that cannot be transported by ordinary conveying equipment.With non-blocking performance,large conveying capacity and strong material compatibility,it is widely used in environmental protection sewage treatment,sludge transportation,industrial ash conveying,chemical viscous materials and domestic waste processing industries.

The equipment adopts unique shaftless spiral propulsion working principle.Driven by the reduction motor,the integral torsion-resistant spiral blade rotates freely inside the sealed U-shaped trough.Relying on the overall torsion and friction pushing force of the spiral body,the materials move forward steadily along the trough lining.Without central shaft obstruction,fibrous materials such as cloth strips,plastic filaments and flexible debris will not be wound or stuck.The contact area between the thick spiral blade and materials is larger,which effectively pushes sticky,humid and agglomerated materials to discharge smoothly.The whole conveying process is stable and continuous,completely avoiding frequent shutdown and blockage failures of traditional shafted conveyors.

The main body is made of high-quality carbon steel or stainless steel according to working conditions.The integral shaftless spiral blade undergoes overall quenching and hardening treatment,featuring high toughness,strong torsion resistance and not easy to deform or break during long-term operation.The U-shaped trough is equipped with replaceable ultra-high molecular wear-resistant lining plate,which reduces blade friction loss,prevents material adhesion and extends equipment service life.The fully sealed trough body with removable cover plates effectively prevents odor overflow,dust flying and material leakage,meeting environmental protection emission standards.Multiple feeding and discharging ports can be customized to realize multi-point feeding and shunting discharging.

Shaftless Screw Conveyor has irreplaceable advantages compared with traditional shafted screw conveyors.It completely abandons the central shaft structure,fundamentally eliminating material winding and dead-angle accumulation,making it the preferred equipment for fibrous and viscous materials.The ultra-thick integral spiral blade has strong bearing capacity and torsion resistance,adapting to heavy-load and impurity-mixed conveying working conditions.The wear-resistant lining design reduces maintenance frequency and avoids frequent replacement of vulnerable parts.The compact structure saves installation space,supports horizontal and small-angle inclined conveying,and has low operation noise and stable running state.

In practical industrial operation,the equipment shows excellent anti-blocking and anti-winding performance.It can stably handle sludge,wet ash,biological waste,fiber debris and mixed granular materials that are difficult to transport by conventional equipment.The fully sealed structure isolates peculiar smell and dust,improving workshop operation environment.Variable frequency speed regulation can be configured to adjust conveying speed and output capacity freely,realizing automatic quantitative conveying.The open trough design with detachable cover plates facilitates daily inspection,cleaning and maintenance without complicated disassembly,greatly reducing later operation cost and downtime loss.

Widely applicable in sewage treatment sludge conveying,dust collector wet ash transportation,chemical viscous material handling,municipal solid waste processing,paper mill fiber residue conveying and building material industrial waste residue treatment projects,Shaftless Screw Conveyor is a professional anti-blocking conveying device.With unique shaftless structure,strong material adaptability and reliable stable performance,it provides efficient and environmentally friendly bulk material conveying solutions for modern environmental protection and industrial supporting systems.
