5T waste bin asphalt batch mix plant with Vibration isolation screen driven by 22KW*2 WAM motor

 

I. Usual faults and elimination of hot aggregate elevator for batch type asphalt mixing plant

 

. Fault:Elevator chains are blocked.

Cause : Capacity is overlarge; screen cannot serve in time, which causes refluence.

Resolvent: Reduce output, open downside discharging door of elevator to discharge accumulated material. Check buckets for damage, and restart.

Cause : Fault appears in screen, or its pores are jammed.

Resolvent: Check and clean up screen, then restart.

. Fault: Chain escapes from underside idler wheel

Cause :The two screws on underside wheel are not equally adjusted.

Resolvent: Readjust the two screws.

Cause : The chains are too loose, and the screws are not adequately adjusted.

Resolvent: Readjust screws. If the adjustment cannot be sufficient, shorten the chains. Refer to the former disassembling method.

 

Bucket type elevator is mainly used for vertical lifting of powder, particle and small block material, which has characteristics of big hoisting height, good sealing effect, small power consumption and wide application area. Bucket type elevator has a wide range of types and Bucket types which meet demands of different working conditions and various materials.

 

Common fault table

Fault Failure cause Elimination/solution

Bucket belt off tracking, chain pressing gear,

eruption of teeth and broken link

Axis of head and tail pulley are not in same plane Readjustment based on installation program
Axis of head and tail pulley unparallel Adjust lower part tensioning till bilateral symmetry
Base plane of head and tail pulley not in corresponding plane Adjust relative location of axial direction and axle base of head/tail pulley
Wear-out failure for sprocket and chain Change head/tail pulley and chain
Bucket touches casing Bucket belt and chain not tensioned Adjust tensioning of bucket belt and chain
Tension to lower limit but still not tensioned Riveting bucket belt again based on installation program
Dismantle a group of chain(for loop chain type, change 1-2 groups of 7-link-chain into 5-link-chain)
Baffle and rail failure Adjust or change baffle or rail
Looseness for bucket fastener Check and tighten bucket fastener

Conveying efficiency declines,

material deposit, jam and block

 

Blocking at discharge outlet Clean and eliminating block

· Displacement for discharging plate and feed back(material returning)

 

Adjust discharging plate position
Excessive feeding amount Control feeding and smooth feeding
Bucket badly broken Change bucket

Mixing of foreign matter, material sticking and hardening

 

Eliminate foreign matter and sticking/hardening material
Material leaking Sealing socket and sealing element failure at head/tail shaft Change sealing element like oil seal
Gasket failure among housing Change gasket
Housing corrosion and damage Change housing
Vibration and noise Moving lubricating point deoiling or foreign matter coming inside Eliminate foreign matter ,clean lubricating point and add grease
Bearing damage or wear at both upper and lower section Change bearing and oil seal
Material sticking and hardening Remove sticking/hardening material
Material blackness out of limits Remove oversize block material and mount mesh at feeding inlet
Bucket damage or deformation Replace unqualified bucket in time
Gear and bearing damage of gearbox Change gear and bearing or change gear box
Equipment stop and bucket reserve rotation Deoiling, dry up or impurity jam in backstop cavity Dismantle. clean and fill clean lithium base grease
Backstop damage,like pine wear and failure Change pin or backstop
Unstable drive Drive chain becomes loose or wear and failure Tensioning of drive chain or changing drive chain
Out of limits for oil in reduction gearbox, gear wearing or damage Clean and change oil, change wearing& damaged gear or driving medium
Power supply or voltage instability, or wiring connector poor contact

· Equip voltage stabilizer, check and correct the wiring

 

 

Unstable flow for material Improve feeding condition of material for smooth feeding
