During the use of the spiral feeder, various problems may be encountered. Below is an analysis of common faults in the use of the spiral feeder, as well as corresponding solutions. I hope it can be helpful to everyone.
1、 Blocked material:
1. Reasonably select the technical parameters of the spiral feeder, such as the speed of the slow speed spiral conveyor should not be too high.
2. Strictly follow the operating procedures to achieve no-load starting and no-load stopping; Ensure continuous and uniform feeding.
3. Increase the discharge port or extend the end of the material trough to solve the problem of poor or untimely discharge. At the same time, a small section of anti rotating blades can be installed at the end of the discharge chute to prevent material blockage at the end.
4. Necessary cleaning should be carried out on the materials entering the spiral feeder to prevent large or fibrous impurities from entering the machine and causing blockage.
5. Minimize the lateral dimensions of the intermediate suspension bearing as much as possible to reduce the possibility of material blockage when passing through the intermediate bearing.
6. Install silo level sensors and blockage sensors to achieve automatic control and alarm.
7. Install an anti blocking valve on the discharge end cover plate. When a blockage occurs, due to material accumulation, the anti blocking door is opened and the power is cut off through the travel switch.
2、 Drive motor burnt out:
1. There are hard blocks or small iron blocks mixed in the material conveyed by the spiral feeder, which can jam the cutter, cause a sharp increase in current, and burn out the motor. The solution is to prevent small iron blocks from entering and maintain a certain gap between the cutter and the casing.
2. The incoming material is too large, causing the motor to overheat and burn out. The solution is to balance the feeding and deliver the materials before stopping the machine.
3、 Spiral feeder casing shaking:
1. During the installation of the spiral feeder, if the centerlines of each spiral joint are not concentric, the eccentric rubbing of the shell will cause the shell to shake. The solution is to reinstall and align the centerlines.
4、 Suspension bearing temperature rise too high:
1. Improper installation of the position, the solution is to adjust the position of the suspension bearing.
2. Hard and large objects mixed into the machine causing abnormal friction. The solution is to clean the foreign objects and test drive until normal.
