Introduction to Spiral Conveyor

1、 Characteristics of Yongtong series screw conveyor products:
- The driving device adopts a gear reducer, which has high torque, low noise, no oil leakage, and long service life. The conveyor shell is connected with high-quality seamless pipes and valve flanges, and the whole machine has good rigidity and high bearing capacity. It can continuously transport whether it is horizontal or large inclination angle during transportation, and can choose the working position and posture as desired. It is easy to disassemble and move.
- It can be loaded and unloaded at multiple points in the middle, and the operation is safe and convenient.
- The tubular screw conveyor adopts high-quality seamless steel pipes, with good sealing performance, no dust leakage, and safe and reliable.
- The U-shaped groove spiral conveyor is easy to disassemble, repair, and maintain
- According to the process requirements, a customized jacket type screw conveyor can be used to achieve insulation, heating, or cooling through the jacket.
- Disadvantages: Heavy wear and tear on mechanical components, low material transportation volume, high power consumption, and easy breakage of materials during transportation
2、 Spiral Conveyor Selection Tips:
Spiral conveyors should not transport materials that are prone to deterioration, high viscosity, or clumping, as these materials will adhere to the screw during transportation and rotate without moving forward, or form material blockages at the suspension bearings, which will prevent the spiral conveyor from working properly. Given the application scope and functional characteristics of screw conveyors, users should fully consider, balance, and select reasonably based on the usage environment and material conveying situation when selecting, in order to avoid unnecessary troubles and losses.

5、 Installation and commissioning of screw conveyor
- Please check if there are any serious damages or deformations to the equipment during transportation, and if there are any loose fasteners on the equipment. Please contact our company promptly.
- Please install equipment, electrical control devices, and accessories correctly under the guidance of professionals.
- Before starting the screw conveyor, please check if there are any objects inside the equipment that may affect its normal operation to avoid jamming or danger.
- After the installation of the screw conveyor, please first conduct a few seconds of trial operation to ensure that there are no electrical short circuits or abnormal sounds before proceeding with the trial run.
- After starting, please check the direction of equipment operation in a timely manner and remember not to reverse it, in order to avoid material blockage or jamming during operation, which may damage the motor and prevent normal feeding and discharging.
- After the equipment is operating normally, please check the bearing temperature, running stability, sealing, etc., and confirm that they are normal before feeding and running. (If there are any abnormalities, please contact our company in a timely manner)
