Their smooth, easy-to-clean surface, free of rust and impurities, meets the hygiene standards of the food and pharmaceutical industries, preventing material contamination.
The core components of a Tubular Screw Conveyor Equipment include the tubular casing, screw blades, drive mechanism, inlet and outlet ports, and bearing assembly. These components work together to ensure a sealed and stable material conveyance.
Conveying pipeline: seamless steel pipe or wear-resistant lined pipe, usually with a diameter of 150-600mm.
Spiral: including shaft or shaftless spiral blades, the material can be carbon steel, stainless steel or special alloy.
Drive device: composed of motor, reducer and coupling, can be equipped with variable frequency speed regulation.
Inlet and outlet device: various interface forms are designed according to process requirements.
Supporting components: including hanging bearings, intermediate supports, etc.
The material enters the conveying pipeline through the feed port, generally below or on the side of the equipment, and the spiral blades rotate under the drive of the motor. Due to the shape of the spiral, the material is thrust during the rotation, so that it moves forward along the pipeline and is discharged through the discharge port to complete the entire conveying process.
