Delivery capacity: 1 ton/hour
Conveying length: 4 meters (angle 20°)
Recommended: WLS200
Advantage:It adopts a fully enclosed structure, which can reduce dust pollution during the conveying process, and can be used in conjunction with other conveying devices to complete collection, distribution, mixing, mixing, dehydration, batching, stacking, etc.
point: There are horizontal, inclined and combined forms, and can be used in conjunction with other devices
Single Shaftless Screw Conveyor—Consists of 1 screw, without mixing function.
Double Shaftless Screw Conveyor—composed of two spirals, the spiral blades rotate in opposite directions, and the conveying capacity is 1.5-2 times that of a single spiral, and can simultaneously perform functions such as conveying, mixing, and stirring.
Carbon steel Shaftless Screw Conveyor—Made of carbon steel, suitable for conveying common materials, mainly used in cement, coal, stone and other industries with high wear and no special requirements.
Stainless steel Shaftless Screw Conveyor—304/316 stainless steel material, corrosion resistance, high temperature resistance, not easy to rust, special for food and pharmaceutical industries. Mainly used in grain, chemical, food and other industries that have requirements on the conveying environment. High cleanliness, no contamination of materials.
Tubular Shaftless Screw Conveyor: Made of seamless steel pipe, good sealing
U-shaped Shaftless Screw Conveyor: Small range/small distance conveying, dust cover is removable
Strong anti-winding: no central shaft design, can convey belt-shaped, viscous materials, easy-to-wind materials, and avoid material clogging.
Large conveying capacity: the torque of the shaftless screw conveyor can reach 4000N/m, and the conveying capacity is 1.5 times that of the shafted one, reaching 458 cubic meters per hour.
Flexible layout: the conveying length of a single machine can reach 60 meters, and multi-stage series installation can be adopted according to user needs.
Sealed conveying: The tank cover with gasket can avoid material leakage, no peculiar smell leakage, and ensure the sanitation of the conveying environment.
The Shaftless screw conveyor is driven by the motor to run the cycloidal reducer, and the screw is rotated by the transmission of the mechanical seal shaft and the connecting plate on the shaftless screw body. When the material enters the feeding port, it is driven forward by the screw blade. Move until the outlet discharges.

Different shapes
The difference is mainly in the blades. The shaftless screw conveyor blades are designed without a central shaft, which is anti-winding.
Conveying different materials
Shaftless screw conveyor is suitable for conveying wet and pasty materials such as sludge, garbage, lime, semi-fluid and viscous materials, materials that are easy to entangle and block or have special hygienic requirements.
Shafted screw conveyor materials are suitable for powder materials, small particle materials, etc. If viscous materials are conveyed, the materials will stick to the blades and cause material blocking.
Different delivery angles
The Shaftless screw conveyor is generally conveyed horizontally, and the maximum inclination angle generally does not exceed 20° (according to actual usage conditions). Shafted screw conveyors can be arranged horizontally, inclined or vertically.
Installation method: The company can provide hanging type according to needs; ground and hanging mixed type; mobile type, rotary type and turret type that can rotate around the axis of the feed inlet.
