Twin Stainless Steel Mixing Live Bottom Shaftless Screw Conveyor

Shaftless Screw Conveyor Description

Shaftless Screw Conveyors are designed to handle almost any bulk material, from dry and free-flowing to sticky and sluggish. Shaftless screw conveyors are ideal for bulk materials with high moisture content that have a tendency to adhere to the center pipe of a conventional shafted screw conveyor.

Shaftless Screw Conveyor Model

Single shaftless screw conveyor screw shaft, without mixing and stirring functions.

Twin Shaftless Screw Conveyor It adopts double screw blades with mixing and stirring functions. The two screw blades rotate in opposite directions to avoid material blocking. The conveying capacity is 1.5-2 times that of a single shaft.
Inclined Shaftless Screw Conveyor mainly used for conveying materials at a small angle of 25°.

Throughput rates: up to 65 m³/h (38 cfm) for sludge, up to 25 m³/h (15 cfm) for screenings

Drive power: 0.55 kW (0.75 HP) to 7.5 kW (10 HP)
Trough and spiral manufactured from carbon or stainless steel 304L or 316L
Trough liner in UHMWP
Small footprint
Odour-free operation
High efficiency- Complete emptying
Simple design (few components)

Shaftless Screw Conveyors VS Shafted Screw Conveyors

Conveying materials

Shaftless is suitable for conveying sludge, household garbage, grid slag and other viscous, entangled materials and massive materials. It is precisely because the design of the shaftless screw conveyor without a central axis has great advantages for these materials.
The shaft screw conveyor is suitable for conveying materials: powder, small particle materials, etc. If you convey viscous
materials such as sludge, it will stick to the inner tube shaft and blades, and the conveying block materials are easy to jam.

Conveying form
Shaftless screw conveyor is suitable for: horizontal conveying, and the large inclination angle should not exceed 20°, according to the actual usage.
The shaft screw conveyor is suitable for: horizontal conveying, inclined conveying, and vertical conveying.

Conveying capacity
Due to the use of shaftless, the single-machine conveying length of the shaftless screw conveyor can reach 60 meters, and the conveying capacity is 1.5 times that of the traditional shafted screw conveyor with the same diameter

Ceramic industry: clay, silica, sand, polishing materials, etc.
Food industry: soybean, peanut, starch, milk powder, salt, sugar, etc.
Plastics industry: plastic powder, plastic particles, etc.
Wood industry:wood chips, wood sawing surface and byproducts, etc.
Environmental: the filter material, fly ash, fixed residue, waste, etc.
Agriculture:livestock feed, food, powder, etc.
