I. Application
The screw conveyor, commonly known as a auger, is a device that uses a spiral shaft rotating blades to push materials for conveying. It features a simple structure, reliable operation, ease of operation and maintenance.
Two, the main structure also operates
The screw conveyor is composed of a cycloidal pinwheel reducer, a coupling (or sprocket and chain), a spiral shaft, intermediate hanger, bearing base, trough, and bracket. The spiral shaft rotates through the reducer and coupling, causing the material entering the spiral housing to move along the trough without rotating with the spiral due to its own gravity and friction against the housing, thereby achieving smooth material transport.
2. Performance Parameters of the 219 Tubular Axial Screw Conveyer

Hengtai Machinery's 219 tube-type shafted screw conveyors are all made of GB standard seamless tubes, with materials including carbon steel, manganese steel, 304 stainless steel, 316 stainless steel, and 310L stainless steel.

Shell thickness is generally 6MM, with increased thickness required for abrasive materials. Blades are made of 16Mn steel, with thickness ranging from 4mm to 12mm, custom cut according to customer specifications. Blade diameter is 187mm, pitch is 180mm, with an allowable tilt angle of 60 degrees. Vertical usage height should not exceed 6 meters, and the maximum conveying distance is 25 meters. A middle hanging bearing is added every 3 meters, which has been significantly improved over the older model products. The material for the hanging bearing is chilled cast iron, known for its strong wear resistance and good practical performance, typically requiring no lubrication or maintenance, and can withstand working temperatures up to 260°C. Particularly suitable for conveying materials such as cement, coal powder, fly ash, quicklime, slag, etc. The drive usually employs a cycloid reducer, and the motor is a first-tier brand. Both the motor and reducer can be customized according to customer requirements.
