Aspects That Should Be Consider While Feed Material Into Bucket Elevator

bucket elevator

Bucket elevator lifting its material by scooper the material at inlet into its bucket and transfer this material to discharge point or outlet. There are few factor have to be consider while feed the material into bucket elevator machine. Usually, when the machine operation its can determine the method and location of the intake. But if there any changes of the intake in inlet machine, a few aspects must be consider that shown in table below.

Aspect Description
Size of inlet The size of inlet can affect the capacity of the machine can be feed in. Generally, when the size of inlet is small, the speed of material fill in should be slower to avoid the inlet of the machine be clog and not fill accurately. Large inlet makes the feed material into the inlet easier but it requires large capacity of the machine.
Upside in-feed devices Normally, the bucket has to be completely turn and moving upward before filling in the material into the bucket conveyor. Then bucket stop moving upward vertically awhile if there is filling the material into it. The load of material was force bucket back to in-feed devices or chute. Due to high friction and vigorous lifting at boot area can cause the damage output and require more power consumption.
Downside in-feed devices When there are changes in feeding material, the internal system previously will be modified suit to the new changes.
Flow rate of operation While operation in feeding material, the flow rate of material filling into the bucket should be steadily with the time taken of feeding material. Whenever these bucket flows too slow the material feed into the bucket can exceed the limit, or when the bucket flow too fast the material not feed enough and can consume more energy.

Working Principle of Link Chain Bucket Elevator

bucket elevator

  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 machine 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 equipment 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.

How to Clean The Bucket Elevator Easily to Save Your Time?

bucket elevator

Cleaning process in bucket elevator is significant in maintaining the life span of the machine. It also can be significant issues in many applications of bucket elevator. Usually, this bucket elevator is widely used in food industries activities in conveying food such as powder, flour, grain and other food materials. By cleaning this machine, we not only can prolong the life services of bucket elevator but we can maintain the efficiency of the machine productivity.

Thus it was important to clean this machine regularly. By using some suitable equipment, open the frame/tubular of the bucket elevator machine. This tubular design allows us to clean with water and reach all the parts of operating components to remove the dissolve material/dirties that attach inside the machine. By open this part also we can allow the machine dry faster at the same times.

If we cannot open the tubular/frame machine, we also can use dry or wet cleaning. We can wipe the buckets and spraying the unit with hot or steam or using compressed air/vacuum suction. In each of these methods have its own advantages and disadvantages in cleaning the bucket elevator system.

What should you know about a belt bucket elevator?

bucket elevator

Generally, a belt bucket elevator needs to be inspected every 6 months for maintenance work. This is especially important for the hopper, belt tightening bolt joints and etc. A belt test is needed to be performed at least once a year to evaluate the service life of the plastic surface of the belt and the belt strength. The level of the cylindrical head and tail roller needed to be adjusted if there’s any deviation occurs. If the deviation is caused by the wear and tear of the drum plastic surface, re-roll the rubber and plastic surface. On the other hand, the rear bearing of the belt bucket conveyor needs to be regularly maintained, as the slip ring seal could be subjected to wear and tear after long time usage. When this occurs, the bearing would be damaged. Here are a few tips for better maintenance of a belt bucket elevator:

  1. a) Check belts for tear, cuts and etc

Any signs of defects should be immediately diagnosed.

  1. b) Check belt tension of conveying belt

This could be the possible reasons for drive slippage and excessive wear. Belts running loosely in a leg are put to severe flex due to lack of full contact with the boot pulley of bucket elevator.

  1. c) Check alignment of conveyor belt

Belt misalignment could cause edge wear and pave way for accidents.

  1. d) Check bucket elevators for uneven loading

This could cause belt to move across head pulley and break the belt fabric.

Maintenance the main parts of bucket elevator machine

bucket elevator

BUCKETS – The bucket elevator machine should be checked to ensure all buckets are attached to the chain or belt and that all bolts are tight. Many times a foreign object will get into the elevator and tear off buckets. This can cause additional buckets to be torn off causing improper operation of the elevator.

CHAIN – The chain should be checked for wear at the barrels, pins, and/or bushings. The best indication of excessive chain wear is when the chain pitch and sprocket become more and more out of phase and the chain barrels or bushings ride higher and higher on the sprocket teeth. Another indication of excessive chain wear is when a continual adjustment of the take-up of the bucket elevator equipment is required.

BELTS – Belts will continue to stretch throughout their service life, but the greatest increase in length will occur during the first part of operation. Be sure to check the boot shaft at frequent intervals to be sure that it is turning. This will indicate the tail pulley is engaged and helping train the belt. A general purpose inspection should be made periodically on all parts of the bucket elevator to insure proper operation of the unit. Be certain to keep the rubber lip located at the discharge chute adjusted as close to the bucket lips as possible. This will help prevent back-legging of material into the boot.
