Kiln axis evaluation

MORE can measure if your kiln axis if it is out of line and determine if it is the cause of crack problems, spalding or bearing overload.

Hot kiln alignment

If the kiln axis is out of line, MORE assists with adjusting the kiln back in line while it is in operation. This is an essential part of all A, B and C checks.

Rolling surface evaluation

The rolling surfaces are measured for cylindricity. If they are conical, concave or convex, they will lock the kiln in a given position, causing the bearing lubrication to degrade faster as well as excessive wear on the bearing houses’ trust collars. This can eventually break the trust collars or cause oil fire. MORE grinds the surfaces back to a cylindrical shape.

Bearing evaluation

To maximize bearing longevity, it is important always to ensure smooth surfaces and clean oil. Without this, the bronze lining will suffer terminal damage within a short time, necessitating a costly repair. It is possible to examine the bearing surface, test the oil temperature, and assess the condition of the collar trust while the kiln is in operation.

Girth gear evaluation

Girth gear and pinion should always run correctly aligned to each other. MORE also checks the drive and measures anomalies, and if necessary helps you align the gear.

Kiln shell evaluation

To ensure a long refractory life, it is essential that the kiln shell is not severely deformed. MORE pinpoints whether kiln shell deformation is the cause of falling refractory . We give you a straight answer about whether you need to repair or replace a sectionn. And how to do it.

FEM (finite element method) analysis

MORE uses a series of measurements as basis for analysing the actual kiln shell stress, the loads on your bearings and the hertz pressure on the rolling surfaces. The result is compared to the ideal situation and tells you how much stress reduction can be gained by aligning the kiln. This is an integrated part of our C check.

General troubleshooting

MORE’s field engineers have a massive level of combined experience from all over the world with almost every brand and type of kiln. It is very probable that we have solved cases similar to your specific kiln problem. As specialists, we pinpoint the cause faster than local staff and suggest a better solution often saving you more than you spend on our expertise. Try MORE’s services if your kiln equipment is not running satisfactorily.

NDT (Non-destructive testing)

It is in many cases not possible to see hairthin fractures where rollers and their shafts are adjoined. Over time, micro-sized cracks will cause the shaft to break off. To test your roller shafts for weakness and more importantly to follow fracture development from year to year, MORE offers optional NDT testing performed with ultrasound equipment.
