Screw Conveyor

Screw Conveyor is a continuous volumetric conveying device designed for horizontal,inclined and vertical transportation of powder,granular,small block and dusty bulk materials.Adopting rotating spiral blade propulsion principle,this enclosed conveying equipment replaces traditional open belt conveying,effectively preventing material leakage,dust flying and environmental pollution.It is widely matched with dust collectors,silos,mixing systems and packaging lines in environmental protection,building materials,chemical,grain and mining industries.With fully sealed structure,stable feeding capacity and flexible layout,it has become the core conveying equipment for modern dust removal supporting and bulk material handling systems.

The conveying process relies on continuous mechanical rotation of the internal spiral shaft.Driven by the reduction motor,the helical blade rotates steadily inside the closed trough or tube.Bulk materials entering the conveyor inlet are pushed forward axially by the rotating spiral blade under continuous propulsion force.Due to the closed pipeline structure,materials move smoothly without rolling and backflow,realizing uniform and continuous material transportation from feeding point to discharging point.The whole conveying process is completely enclosed,which thoroughly solves dust overflow and material waste during traditional material transfer,ensuring clean and environmentally friendly workshop operation.

The equipment body supports diversified material configurations to adapt to different working media and environments.The standard model adopts carbon steel integral welding with anti-rust painting treatment,suitable for ordinary dust,cement powder,grain particles and general industrial materials.For corrosive,humid and food-grade materials,full 304/316L stainless steel customization is available with polished inner surface to prevent material adhesion and corrosion.The spiral blade adopts integral pressing and wear-resistant welding process,with high hardness and strong anti-abrasion performance.Multiple structural forms include tubular screw conveyor,trough screw conveyor and shaftless screw conveyor to meet different material viscosity and conveying distance requirements.

Screw Conveyor has prominent structural and functional advantages compared with other conveying equipment.Fully enclosed design achieves zero dust leakage,perfectly matching industrial dust removal and clean production standards.It features compact structure,small floor space and flexible installation angles,supporting horizontal,inclined and vertical arrangement according to on-site layout.The volumetric conveying mode ensures stable and uniform material output without intermittent feeding or material stacking.Variable frequency speed regulation can be configured to adjust conveying capacity precisely,realizing automatic quantitative feeding.Simple transmission structure results in low failure rate,low noise and long continuous operation cycle.

In practical industrial application,the equipment adapts to multiple complex working conditions.Shaftless spiral structure is available for sticky,wet and easily blocked materials to eliminate winding and jamming problems.Multiple inlet and outlet ports can be customized to realize multi-point feeding and multi-point discharging,improving production line flexibility.All wearing parts such as bearings and spiral blades can be inspected and replaced on site,reducing later maintenance cost and equipment downtime.It supports 24-hour continuous industrial operation with stable conveying efficiency and strong environmental adaptability.

Widely applicable in dust removal ash conveying,cement and building material production,chemical powder transportation,grain processing and storage,mining screening and environmental protection engineering projects,Screw Conveyor is a mature and efficient bulk material conveying solution.With sealed dust-free operation,flexible layout and high cost performance,it provides reliable continuous material transportation guarantee for modern industrial production and environmental protection supporting systems.
