Four Methods to Solve Uneven Rotating Speed of Bucket Elevator Problem

1. Base frame blockage
The reason is feeding prior to start-up, the bucket belt lacks of tension which will cause belt skid, or the inflow rate of feeding is greater than the conveying capacity (including excessive of feeding back), as well as bulk materials enter into the base frame. The methods to eliminate the problem is to shut down the machine at once, close the feeding chute, open the base frame gate plate , clear the clogged material, and start up the machine in accordance with procedures. And also adjust the tension device in order to strengthen the clean up speed of anterior materials.
2. Conveying capacity reduces
The reason is due to the skid of the drive belt or lifting belt, insufficient rotating speed of electrical motor, uneven feeding, serious feeding back, unreasonable selection of bucket design. The methods to eliminate the problem is to adjust the tension device, check electrical motor, eliminate the fault, feed evenly, identify the cause for promptly discharge of material, and select bucket design reasonably.

3. Excessive of material returning back
The reason is the linear speed of belt elevator too fast or too slow, improper design or size of drive head, material discharging in the outlet is not smooth. The methods to eliminate the problem is to adjust the rotating speed of bearing, modify the external dimensions of drive head or adjust the drip plate at the bucket gap, and unblock the outlet.
4. Casing wears seriously and large power consumption
The reason is the installation of bearing tilts, dust deposition on bearing, poor lubrication, bearing failure or elevator belt is too tight, excessive of material returning back, blockage of base frame. The methods to eliminate the problem is to readjust, clean or change the lubricating oil, replace the bearing and adjust it properly. Identify the cause for promptly discharge of material, and clear the clogged materials.
