Commitment:
Screw conveyor is a mechanical conveying system used to transport bulk materials from one location to another. It consists of a rotating screw inside a trough or tube, which moves the material along the length of the trough or tube. The screw is typically made of metal or plastic and has helical flights that act as paddles to move the material.Screw conveyors can be used to transport a wide variety of materials, including powders, granules, flakes, and pellets. They are commonly used in industries such as agriculture, food processing, mining, and chemical manufacturing.
Tubular Screw Conveyor
It is mainly used for horizontal, inclined and vertical conveying of powdery or granular materials. The high speed can ensure smooth, fast and uniform conveying, and it is not easy to jam the material. The sealed pipeline design ensures no dust during the conveying process and the material is not easy to leak.

It is suitable for horizontal/small inclination transportation, the inclination angle does not exceed 15°, and the sealing performance is good, which can avoid the generation of dust during the transportation process. The upper rainproof type cover is detachable, which is convenient for later maintenance and repair.
Shaftless Screw Conveyor
It is designed with no center shaft, which provides a non-clogging conveying surface and eliminates the accumulation of sticky materials, making it especially suitable for conveying pasty materials, semi-fluid and sticky materials, wet and strip materials, such as municipal solid waste, sludge , kitchen waste, household waste, etc.
Double Screw Conveyor
It is composed of two screws and is mainly used when the material needs to be mixed when it moves to the destination. It is divided into two designs: double shaft and double shaftless. It is suitable for conveying poor fluidity, large volume or particle size, and needs to be stirred. materials.
Cooling Screw Cnveyor
It is a conveying equipment that integrates cooling and conveying. It is equipped with a water cooling system. The cooling water flows from the empty pipe at the inlet end through the cavity of the spiral plate and then flows out from the empty pipe at the initial stage to form a cooling water channel. It can achieve the specified outlet temperature of the product and is suitable for conveying High temperature fly ash, cinder, rubber powder, carbon black and other materials.
A screw conveyor works by using a rotating screw inside a trough or tube to move bulk materials from one location to another. Here's how it works:
Material is fed into the screw conveyor through a hopper or other inlet.The rotating screw inside the trough or tube moves the material along the length of the trough or tube. The helical flights on the screw act like paddles, moving the material forward with each rotation of the screw.As the material moves along the length of the trough or tube, it is compacted and compressed by the screw. This helps to prevent the material from becoming aerated or separated during transport.At the discharge end of the screw conveyor, the material is released from the trough or tube. This can be done by using a slide gate, valve, or other mechanism.
Wide range of applications
The scope of application of screw conveyor products is very wide, and can be used in many fields such as storage, food, chemical industry, waste water, etc., and it is used in some industries to mix various materials and break lumps.
