Working Principle of Cement Screw Conveyor

The core components of the  screw conveyor are the screw shaft, the screw blades and the closed shell. The concrete is conveyed from the feed port to the discharge port by the rotation of the screw blades. The motor drives the screw shaft to rotate through the reducer, and the screw blades rotate accordingly. The rotation of the screw blades generates axial thrust, pushing the material from the feed port to the discharge port of the conveyor. The closed pipe or U-shaped groove of the conveyor ensures that the material moves in the specified direction to avoid leakage, while reducing environmental pollution and material waste. By adjusting the speed and inclination of the screw blades, it can adapt to concrete of different consistencies.

Working Progress of Concrete Screw Conveyor

Material feeding

The material enters the conveyor from the feed port, and the feed amount can be controlled by controlling the valve or frequency conversion speed regulation; in order to facilitate the smooth entry of the material, the feed port is located at one end of the conveyor, and the material is fed by the silo, mixing station, manual feeding or other upstream equipment.

Material conveying

After the motor is started, the screw shaft drives the blades to rotate, so that the material is thrust and moves forward continuously and steadily along the direction of the screw shaft. During the conveying process, in order to ensure uniformity, the material will also be subjected to a certain amount of stirring and mixing to avoid material accumulation or blockage.

Material unloading

After the concrete reaches the discharge port, it is discharged from the discharge port by gravity or a discharge valve. After discharge, it can enter the concrete mixer, hopper, storage bin, etc. In order to meet different construction needs, the discharge port is generally designed to be fixed or movable.

Benefits of Concrete Screw Conveyor

Efficient conveying

Cement auger conveyor can realize continuous and stable conveying of concrete without interruption, ensuring the smoothness of the production process and improving production efficiency. It can be conveyed horizontally, inclined or even vertically, with great flexibility, and is suitable for large-scale concrete pouring projects.

Good sealing

The conveyor equipment adopts a closed trough design, which can realize fully enclosed conveying, avoid dust and material leakage, avoid material waste, and help reduce pollution to the environment. It is suitable for conveying harmful or dust-proof materials such as cement and fly ash.

Small footprint

Cement screw conveyor is mainly composed of spiral blades, troughs, drive devices, etc. It has a simple design, compact structure, long equipment life, and low maintenance cost; it can be flexibly installed according to site conditions when in use, and is suitable for construction sites with limited space.

Strong adaptability

Screw conveyor is not only suitable for conveying concrete, but also for conveying powdered, granular, blocky or semi-fluid materials such as sand, gravel, fly ash and grains. It can handle materials of different consistencies from dry hard concrete to fluid concrete, and is suitable for construction, chemical, food and agriculture and other industries.
