Increase life span and cost efficiency of rotary kilns in lime and pulp production

The challenges of rotary kilns in lime and pulp production

Rotary kilns face immense pressure and wear from extreme temperatures, heavy loads and expansion of the refractory lining during production. Risks include deformation of the steel shell, and poor insulation or the wrong combination of materials can lead to a decrease in product quality, as well as costly maintenance and waste of energy.

Harvest the benefits of our back-up insulation systems in rotary kilns

Skamol has developed the SkamoCeramic M-Extra moler brick as a back-up insulation system in rotary kilns. SkamoCeramic M-Extra is specifically designed to provide the kiln with an excellent insulating lining, while at the same time being able to resist the extreme conditions inside the kiln.

Some of the benefits of SkamoCeramic M-Extra include:

• Reduced thermal loss and energy consumption
• Decreased deterioration of mechanical parts
• Reduced costs of relining and production down-time
• Lower risk of shell deformation

Improve the life span of the rotary kiln with our SkamoCeramic M-Eextra

By using SkamoCeramic M-Extra as a back-up insulation system, the life span of the rotary kiln can be greatly increased. SkamoCeramic M-Extra is highly resistant to alkali attacks, providing a protective shield for the mechanical parts and steel shell. The brick structure even increases in strength up to 900°C, giving the kiln increased resistance to the pressure of the expanding refractory lining and thereby also lowering the risk of shell deformation.

Reduce rotary kiln energy consumption with up to 50% wiht our insulation systems

Besides providing a protective shield, SkamoCeramic M-Extra maintains its insulation properties in service temperatures up to 1,000°C, which has been documented to reduce energy consumption with up to 50%.

Fuel consumption and energy reduction

SkamoCeramic M-Extra has a low thermal conductivity, which ensures a lower external thermal loss and gives a large energy reduction compared to an uninsulated kiln. A low external thermal loss also has the consequence that the shell temperature drops, thereby ensuring the shell condition and alignment. A further advantage is that the effect of adverse weather conditions is minimized.
