CHAIN BUCKET ELEVATOR

DESCRIPTION:

1 Bucket Elevator Head

The Bucket elevator head consists of fabricated rigid sections, which are welded to
connecting flanges. Accessibility for inspection and / or maintenance is accomplished by an
inspection door located opposite to the drive location side and other bolted/removable
panels. The drive shaft pillow blocks are supported by heavy consoles which are welded to
the sides of the housing.
2 Self-aligning roller bearings support the drive shaft.

The drive hub is fixed to the drive shaft utilizing a heavy key and 2 set bolts.
The friction ring (in 3 sections) is attached to the drive hub by a high tensile bolted
connection. The diameter of this ring is selected so that the pressure points for chain
bushings and chain links shift with each revolution.

The friction ring is manufactured from appropriate high quality steel and subsequently
hardened. The area for material discharge at the bucket elevator head has wear resistant
liners. Between the bucket elevator head and the bucket elevator casing with the discharge
chute/flange, we will provide a heavy steel frame. This steel frame extends towards the drive
side of bucket elevator and provides a rigid support for the drive gear and motor
arrangement.
The material guide lip next to the buckets and within the bucket elevator discharge area is
adjustable for minimum gap.

1 Bucket Elevator Boot

The Bucket elevator boot consists of fabricated rigid sections, which are welded to the
connecting flanges and to the base frame. For accessibility during erection and for possible
necessary clean-out work during operation, we provide bolted and removable panels at the
sides of the boot.
For inspection purposes there will be 2 doors, each atleast 400 x 300 mm in size located in
the area of the tension shaft bearings blocks.
2 Ni hard sleeve bearings support the tension shaft. Bearing housings are sealed against
dust which is moving within wear resistant guides.
The tension shaft is an oversized heavy and round steel bar, which provides the
counterweight. This feature gives a smooth running of the bucket strand and provides for a
minimum load on the tension shaft bearings.
The feed chute can be attached to the cover plate in the area of bucket elevator feed point.
The bucket elevator will be anchored onto a concrete foundation or a structural steel
support. The necessary fasteners are part of our supply.

Bucket Strand with Central Chain

The chain is an AUMUND development for high performance bucket elevators. Chain
bushings are specially case hardened and the chain pins inductively hardened.

1 Material level Monitor

For monitoring the material level within the boot, a level sensor can be installed, comprising
of :
Mounting flange for sensor attached to bucket elevator boot.
Rod type sensor for clinker.
Membrane switch : "Indicator" for fine materials.

1 Rotation Monitor

For monitoring the operation of the bucket elevator strand, a motion detector can be
installed, comprising of :
Mounting flange for sensor attached to bucket head.
An inductive sensor is provided
Monitor to be mounted to suit local conditions.

1 Dedusting Flange

For dedusting we can provide at the bucket elevator head cover a flange for dedusting duct
connection.

Erection and Maintenance Casing

An erection and maintenance casing is arranged on top of the bucket elevator boot. The
welded connection flanges will have mounting holes for bolts. The rigid fabricated casing
frame will have bolted and removable cover plates for erection and larger maintenance
requirement. For periodic checking we will provide one inspection door at the casing face.

Bucket Elevator Casings

The self supporting casings are fabricated, bent and welded in standard lengths of 3000 mm
and will have welded-on connecting flanges.
Connecting bolts and gasket materials are part of our supply.
With single casings every second pair will be stabilized by an U-channel frame.
To arrive at the proper overall casing height, a special length adapter casings set will be
provided.

Buckets
Buckets are fabricated from steel plate and welded. The bolt holes for
Bucket fastening are selected based on the chain to be used.

avoid any delays of deadlines, it has to be confirmed upon award of order whether the
customer will effect the acceptance.
In the framework of the acceptance the customer can :-
- effect visual controls
- check the dimensions of construction parts
- look at parts' lists for control of pre-assembled construction parts.

Liquidated Damages due to Delays in Delivery :

In case delivery of the equipment is delayed beyond the agreed dates, Liquidated damages

loss of production etc.

Performance guarantee

If the guaranteed conveying capacity of the installation is not fulfilled, we reserve the right to
exchange parts at site free of charge to you within 6 months from date of commissioning, in
order to achieve the promised capacities.

Assembly/Supervision of commissioning

For the supervision of the erection and commissioning we recommend one of our
supervisors.

- Assembly

Should you decide not to request the delegation of an AUMUND supervisor you should
be aware of the fact that commissioning would take longer due to the necessary check-
ups.

- Commissioning

The employment of an AUMUND supervisor is the condition for our acceptance of any
possible warranty claims resulting from AUMUND's contractual obligations. If you do not
use our supervisors for the commissioning you will be abandoning your claims on the
warranty.

Assembly, commissioning and acceptance interruptions

Regarding the assembly, we assume a trouble-free course without any idle time caused by
the customer as well as any external influence. For any possible assembly delays for which
AUMUND is not responsible (e. g. insufficient access, obstacles, operational failure,
provision defaults, missing energy, bad weather, frost etc.) the costs will be to customer's
account and will be invoiced at the rates being valid upon assembly.

In case, deadlines are not met for reason that AUMUND is not responsible, the deadline
commitments including penalty and further indications concerning deadlines will become
invalid and will have to be re-negotiated.
