Lime Industry

At the forefront of perfecting lime production.

With over 35 years of experience in the Lime industry Mathios Refractories S.A. is one the experts in providing EPC refractory designs for Lime plants. We are in the position to effectively solve the refractory linning problems of our partners and adapt to the short delivery times for the materials they require. We have been providing our high quality prouducts in all parts of the plants, providing bricks, monolithic, precast sections as well as special parts.

  • Lime Shaft Kiln
  • Lime Rotary Kiln

By understanding of the production process behind the lime industry, Mathios Refractories S.A. focuses on improving energy efficiency, reduced downtime and shorter repair cycles of those plants.

Lime Shaft Kiln

Nose Ring Discharge Combustion Zone After Burner Chamber Upper Part
Safety Lining Combustion Zone Insulating Lining

Lime shaft kilns convert limestone to lime through a process known as calcination. Throughout the years we have gained vast experience in many large lime kiln projects both domestically and abroad. This experience has established, among others, the necessity of the safety layer which comprises of alumina bricks and is located between the wear and insulation layers. This safety layer can protect the insulation layer and kiln shell in case of lime infiltration or wear layer failure, avoiding thus extremely costly and time consuming repairs.

The refractory materials offered by MATHIOS REFRACTORIES are vastly tested and proven by the lime industry around the world. Products from the following lines are recommended by our experts:

  • IDEAL: Alumina (Al2O3) bricks, with formulations based on calcined fireclay, mullite, andalusite and bauxite are used as inlet, sintering, safety and cooling zone linings
  • MAT PLUS: Alumina (Al2O3) low cement castables (LCC), with formulations based on chamotte, are used at the inlet and cooling zones
  • MAT PLUS MC: Alumina (Al2O3) medium cement castables (MCC), with formulations based on chamotte, are used at the inlet and cooling zones
  • MAT: Alumina (Al2O3) regular castables (dense), with formulations based on chamotte, are used as concrete sealing ring refractories
  • MAT: Alumina (Al2O3) insulating castables, with formulations based on chamotte, expanded clay and perlite, for use as top insulation lining
  • IDEAL: Magnesite (MgO) bricks, with formulations based on magnesia and magnesia-spinel are used as burning and sintering zone linings
  • MATH: Insulation bricks, with formulations based on alumina and perlite, for use as insulation lining

Lime Rotary Kiln

Sintering Zone Transition Zone Calcination Zone
Preheating Zone Cooler

Lime rotary kilns convert limestone to lime through a process known as calcination. As rotary kilns, they impose a different blend of  thermo mechanical stresses  on their refractory linings, in comparison with shaft kilns.

The refractory materials offered by MATHIOS REFRACTORIES are vastly tested and proven by the lime industry around the world. Products from the following lines are recommended by our experts:

  • IDEAL: Alumina (Al2O3) bricks, with formulations based on calcined fireclay, mullite, andalusite and bauxite are used as preheating, sintering, calcination zone and cooler linings
  • MAT PLUS: Alumina (Al2O3) low cement castables (LCC), with formulations based on chamotte, mullite and andalusite, are used as preheating, sintering and transition zone linings
  • MAT PLUS MC: Alumina (Al2O3) medium cement castables (MCC), with formulations based on chamotte, are used as cooler linings
  • MAT MICRON: Alumina (Al2O3) ultra-low cement castables (ULCC), with formulations based on sintered mullite and andalusite, sintering, transition and calcination zone linings
  • IDEAL: Magnesite (MgO) bricks, with formulations based on magnesia-spinel are used as sintering zone linings
