4 key factors decide the function of bucket elevator

 Bucket elevator can be installed singly or in a system, in order to meet the needs of the site and materials forms. The main parameter of the bucket elevator is according to the handling system, loading and unloading location conditions, production process and the characteristics of transported material,main aspects are as follows:
1. Conveying capacity: it means the amount per hour, usually calculated in weight or volume.
2. Conveying speed: improving the speed can increase the elevating capacity. Especially when use the belt bucket elevator for long distance transporting,it needs to improve the conveying speed, but if use chain bucket elevator you should not, in case of enlarging the burden.
3. Pats dimension: the dimension of parts include belt width, plate width, bucket volume, channel diameters and so on, these dimensions will have an impact on the conveying capacity.
4. Conveying distance: the total distance will have an impact on the total resistance and power.

►Introduction
It is designed for transporting vertically for granular, powder and small block of grinding suction smaller disperses the shape material. It adopts belt as the traction component , can reach to max.40 meters . Capacity could be approx. 4~238m3/h .
Working Principle
The bucket is filled with material and is conveyed to the head terminal, and then the material is thrown from the outlet under the action of centrifugal force according to the parabolic design. The driving device drives pulley to operate the bucket belt in circular motion from bottom to up. After discharging, the empty bucket is back to the boot by conveying and be filled again, and then lifted up to do parabolic motion such repeated cycle. The material is lifted from bottom to the top to the specified height to reach conveying vertically.
Features
    1.Smooth transmission – no impact caused due to the traction member
    2.Less noise pollution – good sealing sound system

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)?
