Maerz Ofenbau AG - The world leader in lime kilns

Lime and dolomite are basic raw materials that are vital in the steel, building and chemical industries as well as in agriculture and flue gas purification. They have made an essential contribution to many of the achievements of our modern world.

As the longstanding leading manufacturer of lime shaft kilns, Maerz Ofenbau AG has extended its range of products in the kiln sector:

Alongside the PFR shaft kiln, which is world-wide the most important calcining system for the manufacturing of highly reactive burnt lime, due to its low specific heat consumption, Maerz now also offers a single shaft kiln for the production of low reactive lime, as well as rotary kilns for high output capacities. For special applications, for example in the PCC and in the soda industry, Maerz has an annular shaft kiln and - for processing of the smallest grain sizes - the suspension calciner, in its range of products.

Maerz is your competent partner not only in calcining, but also in the processing of limestone and lime. Maerz plans and constructs complete plants for the crushing and screening of limestone and for the manufacturing of lump, fine and hydrated lime.

Together with its customers, Maerz develops tailor-made concepts and plants for the production of lime. Our core competences lie in process engineering, overall planning, plant construction, project and contract administration and service.

The name Maerz stands world-wide for innovative, energy optimising and environmentally compatible solutions for the lime industry.
