1. Non-load running
After the completion of the installation work, then you can run without load. Before non-load test, please guarantee the chain rotates on the sprocket jogged run for around two weeks or more, when there is no touching or abnormal sound ,you can continue non-load running. During non-load running, please check the current and voltage of the main motor and make record, measure the temperature rising of the gearbox bearing parts and each bearing of bucket elevator head &tail section at the same time.
After the non-load running for 4 hours, if there is no abnormal phenomenon, you can stop, and tighten all bolts once more which fixed the buckets. Because buckets are in the right position now during non-load running, after tightening the screws well, non-load running once again for more than 4 hours, then stop. Tight the bucket connecting bolts again, then weld the bolts and nuts well by spot welding.

2. Load operation
Bucket elevator already meets the load operation after finishing non-load running, you can run with load after confirming there is no problem with other connected devices. At the start of the load operation the load should be increased from minimum to maximum gradually. In the process of load operation, the please measure the motor current ,voltage and the bearing temperature rising condition and make record, in order to make assessment of trial run, performance, and working condition for the whole machine.
3. Operation
1) Start-up
Bucket elevator will meet the normal operation conditions when load linkage test running is completed. 1-3 minutes non-load running is required before the normal work, then increase the feed rate gradually after operation becomes stable till reach full load operation.
2) Shut-down
Please confirm there is no remaining material inside the buckets after stopping feeding , then running for a period of time again and stop running to ensure that materials in the buckets are all discharged.
