Classifications Classified by screw shaft type:. Shafted double screw conveyor: Two screws with a central shaft.

For free-flowing materials such as powders granules and small lumps including cement fly ash flour and grain. Shaftless double screw conveyor (double shaftless): The central shaft is removed and the blades are driven from the ends.

For viscous, easily tangled materials such as sludge, municipal solid waste, kitchen waste, and fibers. Classified by trough shape:.

U-shaped double screw conveyor (trough type): An open double trough with a cover plate on top for easy maintenance and observation.

For horizontal or slightly inclined conveying and the most common type. Tubular double screw conveyor: A fully enclosed double-tube structure with excellent sealing against dust leakage.

It can convey at large angles and is for dusty materials such as cement and fly ash. Classified by function:.

Conveying type: Mainly for conveying, with simple mixing.

Mixing type: The blades are arranged in a reinforced interlaced layout and a spray device can be fitted with uniform mixing.

Humidification and stirring while conveying. Cooling/heating type: The trough is jacketed and can be supplied with cooling water or heat transfer oil.

Controlling the temperature during conveying. Classified by conveying direction:horizontal, inclined, and vertical.has and.

Large capacity and high efficiency: The two screws work side by side effectively doubling the conveying cross-section and increasing throughput markedly compared with a single shaft of the same diameter.

Integrated conveying mixing.

And breaking-up: The two screws rotate in opposite directions and produce strong shearing and tumbling action on the material.

Completing mixing stirring breaking-up and humidifying as it conveys so one machine several duties. for difficult materials: It has particular strengths for materials with poor flowability that cake or bridge easily or contain fibers.

The forced pushing of the two screws effectively stop bridging and blockage. Smooth synchronous operation: The gear-driven synchronous transmission keeps the two screw shafts rotating at exactly the same speed in opposite directions.

Giving smooth running little vibration and low noise. Sealed and environmentally friendly: The fully enclosed trough and multi-layer bearing seals effectively stop dust leakage.

Improve the working environment and meet environmental protection requirements.

Flexible layout: It can convey horizontally or at an incline (≤15°) with inlet and outlet points at several positions.

And can also convey in reverse; it can be connected and fixed directly to matching equipment without a foundation.

Easy maintenance: In the LS type the head and tail bearings are mounted externally the hanger bearing has an external oil cup for centralized lubrication.

And the discharge end has a cleaning device; the U-shaped trough cover can be opened for internal inspection and cleaning.

Wear-resistant and durable: Thickened helical blades and trough with optional wear-resistant liners (manganese steel.

Nylon or polyurethane); worn blades can be repaired by welding, giving a long service life.

Material options and high customization: Carbon steel 304/316 stainless steel manganese steel and other materials are available to suit different conditions such as food.

Chemical and corrosive service; trough width, length, speed, spray device, and jacket heating/cooling can all be customized.
