Single Tube Spiral Feeder Overview

The single-tube spiral feeder is used to convey dry and powder material continuously, such as raw material, coal powder, and cement powder to convey in a short distance. It is used to feed material at the bottom silo.

Features

Material is not easy to block in the inlet. Thus it can guarantee a high filling rate of powder material in conveying pipeline.

Different screw impellers of the inlet opening can mix the material evenly and it will be easy to feed. The structure of the whole screw impeller complies with the conveying regulation of material receiving, providing and steady flow. Thus the even filling rate in the pipeline is guaranteed.

The products of this series have I-fixed speed, II-manual, and no grade tunning speed according to the driving way. All use high-efficiency and high-ratio cycloid pin wheel reducers. Type II is matched with a new electromagnetic tunning speed motor. It is characterized by a wide tunning speed range, stable driving, low noise, and tight structure and it is easy to adjust material flow and meets different manufacturer requests.

Single Tube Spiral Feeder Details

The single-tube spiral feeder is widely used in thermal power generation, cement, paper mining, forestry, building materials, and other industries. The equipment runs & discharges smoothly. The tube spiral feeder can operate reliably in harsh environments. And there is a vibration device at the bottom, and the overall structure is compact in design. No material remains in the bag after unpacking.

Structures & Working Principle

Single Tube Spiral Feeder Structures
The single-tube spiral feeder is mainly composed of a feed port, spiral blades, cylinder, driving device, discharge port, and other parts.

Single Tube Spiral Feeder Working Principle
During operation, after the material is transported to the casing of the single-tube spiral feeder through the feed port, the material is affected by centrifugal force and tube wall friction in the internal spiral groove, rotates with the spiral blades, and is driven by gravity under the action of gravity. The material slides down along the spiral groove, so that the material is continuously pushed forward and transported, and finally discharged evenly from the discharge port.
