The shaftless screw conveyor is a special type of screw conveyor without a central shaft.It uses an integral thickened helical flight as the conveying body,running inside a U-trough or tubular casing.It is specially designed for sticky,wet,winding,bulk and easy-blocking materials that ordinary shaft screw conveyors cannot handle.

Core Advantages

No central shaft,no clogging

Without a central shaft and hanging bearings,materials will not wind or stick to the shaft,solving blockage thoroughly.

Strong adaptability

Perfect for wet sludge,garbage,biowaste,paper pulp,kitchen waste,sticky powder and fibrous materials.

Large conveying capacity

The full-space spiral design makes the effective conveying area larger than traditional screw conveyors.

Wear-resistant&long service life

Equipped with replaceable lining plates,anti-wear and corrosion-resistant,reduce maintenance cost.

Fully sealed&environmental friendly

Closed trough structure,no dust leakage,no odor overflow,clean and pollution-free.

Structure&Material

Main body:Carbon steel/Stainless steel 304/316

Liner:Wear-resistant rubber,polyethylene or alloy liner

Layout:Horizontal,inclined,large angle conveying available

Application Industries

Widely used in wastewater treatment,municipal solid waste,environmental protection,chemical,food processing,paper making,farm breeding for conveying sludge,domestic garbage,organic waste,fiber and sticky materials.
