Product BrochureProduct Details:

Cement screw conveyor is bulk material handling equipment, which usually consists of a tube containing either a spiral blade coiled around a shaft (sometimes called an auger), driven at one end and held at the other. The main parts include tube, shaft with spiral blades, inlet and outlet chutes, as well as driving device. 
Working Principle      

A cement screw conveyor is a specialized type of conveyor system used in the construction industry for transporting cement or other materials in powder or granular form. Its working principle involves several key components working together:

1. Screw or Auger: The core component of the conveyor is a helical screw or auger that rotates within a trough or casing. The screw is usually made of metal and has a helical shape that allows it to move material along its length when rotated.

2. Hopper or Inlet: Material is loaded into the conveyor through a hopper or inlet at one end. The hopper typically has a gate or valve that controls the flow of material into the conveyor.

3. Rotation Mechanism: The screw is rotated by a motor or other power source located at one end of the conveyor. The rotation of the screw pushes the material along the length of the conveyor.

4. Trough or Casing: The screw is housed within a trough or casing that contains the material being transported. The trough is typically made of metal or reinforced plastic and is designed to withstand the weight and pressure of the material.

5. Bearings and Seals: Bearings are used to support the shaft of the screw and allow it to rotate smoothly. Seals are used to prevent material from leaking out of the conveyor along the shaft or at the ends of the trough.

6. Discharge Outlet: At the opposite end of the conveyor from the inlet, there is a discharge outlet where the material exits the conveyor. The outlet may have a gate or valve to control the flow of material out of the conveyor.

The working principle of a cement screw conveyor involves the rotation of the screw, which creates a continuous flow of material from the inlet to the outlet. As the screw rotates, the material is pushed along the length of the conveyor and discharged at the outlet. The speed and direction of rotation of the screw can be adjusted to control the flow rate and direction of material movement. This type of conveyor is commonly used in construction projects such as concrete batching plants, where cement needs to be transported from storage silos to mixing equipment.
