Feed screw conveyor machine

The pipe spiral conveyor consists of a spiral shaft, spiral blades, a driving device, a seamless steel pipe shell, and an inlet and outlet. Its working principle is: the motor drives the spiral shaft to rotate, driving the spiral blades to push the material horizontally, obliquely, or vertically in the closed pipeline. The directional conveying of materials is achieved through the thrust generated by the rotation of spiral blades and the frictional force on the pipe wall.

Blade type: Choose solid surface type (suitable for dry powder materials) or belt surface type (suitable for granular materials) based on material characteristics (such as powder or granular).

Sealing: The shell is made of seamless steel pipe, connected by end flanges, and equipped with dust-proof devices to prevent dust leakage.

2、 Core Performance and Selection Points

Applicable materials: loose materials in powder, granular, or small pieces (such as coal ash, cement, and grain), not suitable for materials that are prone to agglomeration, high viscosity, or spoilage (such as wet sludge).

Drive configuration: Standard gear reduction motor, optional variable frequency speed regulation to meet different conveying capacity requirements.

Material requirements: The spiral blades and shell in contact with the material should be made of stainless steel or food grade carbon steel to prevent corrosion and contamination.

4、 Industry application scenarios

Feed processing: Transporting raw materials such as corn and soybean meal to mixing equipment, or in the packaging process of finished products.

Building materials industry: Closed transportation of cement and fly ash to reduce dust pollution.

Grain storage: horizontal transportation and vertical lifting of grains and flour.

5、 Advantages and disadvantages analysis

Advantages:

Strong sealing performance, reduces dust overflow, and meets environmental protection requirements.

Compact structure, flexible installation, adaptable to complex site layouts.

Modular design, easy maintenance (such as using self-lubricating materials for hanging bearings).

Limitations:

Not suitable for materials with high viscosity and easy clumping, which can cause blockage or blade adhesion.

Adding intermediate suspension bearings during long-distance transportation may increase maintenance costs.

6、 Maintenance and Precautions

Anti blocking measures: Regularly check the wear of the blades, and increase the cleaning frequency when transporting materials containing fibers.

Installation requirements: Ensure that the flange connection of the shell is tightly sealed to avoid material leakage
