Skamol offers M-EXTRA moler bricks as back up insulation in rotary kilns. M-EXTRA is designed through careful field-testing and the bricks have excellent insulation properties combined with exceptional strength, providing the following benefits:
By using M-EXTRA it becomes possible to significantly increase the life span of the rotary kiln and save energy at the same time. By maintaining its insulation properties in service temperatures up to 1,000°C, M-EXTRA has been documented to reduce energy consumption with up to 50%! Follow the link to our Heat Transfer Calculator and find out how much heat loss you can achieve by using M-EXTRA.
M-EXTRA’s material composition makes it resistant to alkali attacks, which shields the mechanical parts and steel shell of the kiln. The brick structure increases in strength in temperatures up to 900°C, which gives the kiln increased resistance to the pressure of the expanding refractory lining, thereby also lowering risk of shell deformation.
