2014-12-31 09:26:06 During the use of the screw conveyor, the intermediate suspension bearing is easy to block the material and the screw loading conveyor is very sensitive to the material, because the screw conveyor has a small space for conveying materials. Therefore, the blockage of the screw conveyor is a common phenomenon in the work of this machine. If it occurs, it will affect the normal use of the machine, increase the power consumption, and even burn the motor, and the screw shaft will be broken, which will affect our normal work.  There are many reasons for the screw conveyor to block the material. What are the measures to prevent the blockage from mechanical analysis:   1. Strictly implement the operating procedures to achieve no-load start and no-load stop; ensure continuous and uniform feeding.   2. The various technical parameters of the screw loading conveyor should be selected reasonably, if it is a slow screw loading conveyor, the speed should not be too large.  3. It is necessary to enlarge the discharge opening or lengthen the end of the trough to solve the problem of poor discharge and too late to discharge. At the same time, a small anti-rotation blade can be installed at the end of the trough of the discharge port to prevent the end from blocking the material.   4. Open an anti-blocking valve on the discharge end cover. If the blockage occurs, it is due to material accumulation, open the anti-blocking door, and cut off the power supply through the travel switch.   5. Necessary cleaning of the materials entering the conveyor to prevent large impurities or fibrous impurities from entering the machine and causing blockage.   6. The transverse dimension of the intermediate suspension bearing should be reduced as much as possible to reduce the possibility of material blocking when the material passes through the intermediate bearing.  7. When installing the silo level indicator and clogging sensor, automatic control and alarm should be realized.
Every day of the year, there is some city or town in the world that is changing over to for container loading machine.
