Cusomized Design and Build Shaftless Screw Conveyor for 

Material: Biosolids


Product General Description:

Shaftless Screw or Spiral Conveyor are an alternative concept to traditional shafted screw conveyors. Material is conveyed by an extra heavy-duty shaftless screw that slides on a wear-resistant, low-friction liner inside the conveyor trough housing.

The shaftless conveyor is the ideal solution for transporting and dispensing sludge or mud from centrifuges, compactors and mixers. The shaftless design provides the opportunity to transport viscose and thick materials without worrying about it clogging up the shaft. It also allows the conveyor to work when it is 100% full, which makes the conveyor much more efficient. And the simplicity saves both space and money.

Applications:

Municipal (management of residues and waste water)

Industrial (food industry, chemical industry, pulp, paper and incineration plants, etc.)

Quantum has extensive experience in the correct selection and design of screw conveyors, screw dischargers, hopper unloading and screw metering systems. The above list is typical of the type of equipment we have supplied to a variety of industries for varying applications. Whether your process and application requires mixing during conveying, dewatering, batch metering interlocked to weigh system or conventional transfer conveying we have the experience and standard equipment to ensure you have a reliable trouble free installation.

Throughput rates are on base of sludge material and valid for a max. Installation angle of 5 degree.


Typical Benefits

Low operational cost:

• There are no sealing joints, bearings, or ball bearings.

• There is no risk of obstruction.

• Fills the container 50% more than the shafted screw.

• The conveyors can be horizontal, inclined or vertical.

• Removable wear cover.

Occupies a small amount of space:

One end of the screw base is connected to the reductive motor. The other end is free, which allows an axial or angular connection to another conveyor and a direct transfer of the load.


Typical Design Features


Screw/Spiral

The unique design of the shiftless screw allows for higher filling rates and lower RPMs - resulting in less wear, and consequently less demands for repair and down time.

No intermediate or end bearings

The more moving parts in a piece of equipment, the more faults that can occur. By eliminating intermediate and end bearings, the need for major maintenance work is reduced.

Excellent Inside liners

Low Friction Liner Materials – UHMWPE or others

Totally enclosed troughs

U-troughs are commonly made out of stainless steel, however they are also available in mild steel painted, galvanized Steel, Wear-resistant Alloy or FRP/GRP etc.
