Powder Screw Feeder Conveyor for Vertical Packing System

Screw Feeder Conveyor Product Introduction

The Screw Feeder Conveyor is a reliable material handling solution designed for continuous transportation of powder, granular, and dry bulk materials. It uses a rotating screw blade inside a tubular conveyor body to move materials smoothly and evenly from the feeding point to the discharge point.

With its compact structure, sealed conveying design, and simple operation, the Screw Feeder Conveyor is widely used in industries requiring efficient and controlled material transfer. It is suitable for handling cement, fly ash, sand, limestone, chemical powder, grain, fertilizer, and other dry materials.

The tubular design helps prevent dust spreading during transportation, making it suitable for environments requiring cleaner production. The conveyor features fewer spare parts, easy installation, and convenient maintenance, reducing downtime and operating costs.

The Screw Feeder Conveyor can be customized according to different conveying distances, installation conditions, and material characteristics. It is an ideal choice for automated production lines, storage systems, mixing equipment, packaging systems, and bulk material processing applications.

Working principle

The Screw Feeder Conveyor operates through a motor-driven spiral screw shaft installed inside a tubular housing. When the screw rotates, the spiral blade pushes powder and granular materials forward along the conveyor tube. The enclosed structure ensures stable transportation while reducing dust leakage and material loss. By controlling the screw rotation speed, the feeding capacity can be adjusted to meet different production requirements.

Equipment Structure

Tubular Conveyor Body

The cylindrical conveyor housing provides a sealed pathway for material transportation and protects the internal screw blade.

Spiral Screw Blade

The spiral blade welded on the center shaft rotates to push materials continuously toward the discharge outlet.

Feeding Port

The feeding inlet allows materials to enter the conveyor smoothly from hoppers, storage tanks, or processing equipment.

Discharge Port

The discharge outlet transfers materials accurately to mixers, storage systems, packaging equipment, or other production machines.

End Bearing Assembly

The bearing structure supports stable screw rotation and improves equipment durability.

Shaft Sealing System

The sealing system helps prevent material leakage and protects internal components during operation.

Support and Connection Components

Flanges and connection sections allow convenient installation, assembly, and maintenance.
