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
	Tension to lower limit but still not tensioned	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
Equipment stop and bucket reserve rotation	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
