tz-belt bucket elevator
►Application
    The vertical belt bucket elevator is widely used in mining , metallurgy , chemicals , power plant , agriculture and quarry etc industries for handling products such as cement, raw meal, alumina, coke, foundry sand, wood chips and other materials.
Maintenance
    A general belt bucket elevator inspection every six months, mainly on the hopper and belt tightening bolt joints check processing, tightening or replacing bolts. Each belt test once a year to confirm the age of the plastic surface of the belt and the belt strength. Adjust the level of the cylinder head and tail roller to correct the belt deviation. If the deviation is caused by drum plastic surface wear, re-roll the car hanging plastic and rubber surfaces. The rear bearing need to regularly check. Generally, after a long time usage, it will cause wear on slip ring seal. This can cause the bearing oil drip and caused bearing damage. Generally, a good slip ring seal can be used for many years.
    A.Check belt for tears, cuts and etc
Sudden signs of unusual damage call for immediate action.
    B.Check cups for loose or missing bolts
A loose dangling cup is the necessary lever to start a busted belt rip.
    C.Replace belt cups
Cups with a pronounced forward bend hold the belt in a vertical arc, which is a contradiction of forces. When the belt is bent in a horizontal arc around the pulleys, this will cause lengthwise cracks to appear at the bolt holes.
    D.Check belt tension
This is a possible source of drive slippage and excessive wear. Belts running loose in a leg are put to severe flex due to lack of full contact with the boot pulley. A loose belt may swing causing the cups to catch and tear the belt.
    E.Check alignment
Belts not running true due to out-of-plumb pulleys, idlers or casing cause edge wear and pave the way for costly accidents.
    F.Check slippage on drive pulleys
Proper lagging of pulleys can increase efficiency and belt life appreciably.
    G.Check bucket elevators for uneven loading
This can cause the belt to crawl across the head pulley and cause edge wear or break the belt fabric.
    H.Check boot for water
A belt allowed to sit in water will rot and tear very easily.
    I.Check discharge throat
The throat to the down leg should be closed as much as possible with a piece of rubber belting adjusted close to the cups. This will prevent back legging.

Selection condition
    1.What are the conveying material and its physical characteristics?
(bulk density, feeding size, temperature, moisture content and etc)
    2. What is the processing capacity of the elevator?
    3. What is the lifting height of the elevator (distance between inlet and outlet)?

What shall we do when the bucket elevator blocked?

If there is blockage, please stop feeding material immediately, if serious ,please stop the machine and check the cause of blockage. Please use a shovel or special tools to clear up the blocked materials instead of hands.


1.If blockage is caused by big lump material entering into the base , please stop machine ,remove big lump materials and plugging materials.
2.If blockage is caused by insufficient tension of bucket belt, please adjust the tension after removing plugging materials. 
3.If blockage is caused by large feed flow rate which exceeds the bucket elevator capacity, please adjust the control valve or use other methods to control the flow rate after removing plugging materials .
4.If blockage is caused by feed before start-up, please remove plugging materials, start up the bucket elevatoragain and operate in strict accordance with the rules. You can only feed the materials after non-load running is normal.
