1.4 Polscan Services

The POLSCAN measuring system of ThyssenKrupp Polysius offers great precision for

rapid and exact measurement of rotary kilns during operation and reliable diagnosis of

deviations. During the measurements, all measurement procedures are computerised

and analysed in order to ensure high accuracy.

1.4.1 Determination of rotary kiln axis

Foundationsettlements,unevenwearorinadequaterepairsresultinoverloadingofindividual

components.

With the determination of the rotary kiln

axis (a measurement which constitutes

the basic procedure of the POLSCAN

Service), it is possible to determine me-

chanical changes of the kiln stations and

to assess their affects on the kiln shell,

tyre, supporting roller axes and supporting

roller bearings as well as on the

mechanical stress of the refractory

bricklining.

The following scope of measurements and evaluation will be carried out:

Determination of the diameters of the supporting rollers and tyre of each station to

analyse uneven wear on the surface and recommend actions such as grinding

Determination of the relative movement in case of floating tyres

Measurement of the temperatures of the tyres and in the vicinity

Measurement of the concentricity of all supporting rollers

Measurement of the foundation bench marks (if available)

Take readings on the kiln for calculation of kiln axis

Measurement of the measuring points on the for calculating the kiln axis

Calculation of the axial position of the rotary kiln

Determination of the axial position of the rotary kiln

Visual inspection of the kiln

Preparation and printout of measurement protocols

1.4.3 Determinination of kiln shell ovality

To avoid damage to the kiln shell and the refractory brick-lining in the area of the tyres,

an examination of the kiln shell ovality is advisable. The measurement is carried out by

high resolution ovality beam made by Polysius, which is quite unique all over the world

and which electronically records and stores all the data and transmits them by radio data

transmission to a data-logger. The result of each ovality measurement sequence can be

seen on the Display as a high resolution graph while the measurements continue. Later

the data will be downloaded from the data-logger to a computer for further data pro-

cessing.

These measurements help to monitor the status of clearance between the tyres and the

kiln shell, which in turn results in being a tool to shim the tyres to keep the ovality within

By maintaining minimal ovality values, the service life of the refractory near the tyre sec-

tion (where the highest ovality values exist) will improve. This measurement should be

included in every preventive maintenance program of refractory-lined equipment.

The following scope of measurements and evaluation will be carried out:

Marking of the measuring planes at the inlet and outlet side of the tyres

Measuring of the deformations of each measuring plane on both sides of the tyre

shell at three measuring points displaced by 120 to each other

Measuring of the actual shell temperatures of each measuring plane

Measuring of the relative movement between tyre and kiln shell in case of floating

tyres

The adjustment of the supporting rollers to be carried out by Polysius requires the ser-

vice of a second kiln expert!

b.) Determinationofkilnaxisafteradjustmentofsupportrollers

After the adjustment is completed we recommend new rotary kiln measurements to doc-

ument the set kiln geometry. Based on these measured data additional calculations can

be carried out at a later date to ensure a straight kiln axis when changes in the kiln ge-

ometry such as replacement of roller, shimming of tyre or machining of roller/tyre have

been performed.

This re-measurement of the kiln axis requires one additional day.

1.5 Documentation / Recommendation / Cd Rom

All the measurement data are stored and remain available at any time for subsequent

calculations. After the completion of the measurements, a set of documentation with ex-

plicit reports will be prepared, discussed with the customer and handed over on site im-

mediately.

Moreover, a written report explaining the measurement records will be prepared as well

as recommendations concerning the mechanical optimisation of the plant, determined

within the measurement.
