Maerz Ofenbau AG. Lime Kilns. Worldwide.
We are driven by fire. Back in the sixties our engineers built the first Maerz lime shaft kilns with a lot of passion, thus laying the foundation for our success. Thanks to numerous innovative milestones we were able to strengthen our position as world market leader.
In so doing we demand the highest standards of quality from ourselves. This goes down well with our customers: Maerz kilns are in operation in over 600 plants in more than 60 countries worldwide. Our continued success over more than half a century is built on a simple common denominator: Passion. It drives us to improve even further, every day.
SUCCESS ALONE DOESN’T SATISFY US.
As the world’s no. 1 lime kiln manufacturer, we could just sit back and relax. Not us. We want to outdo ourselves – for our customers, whom we thank for our success.
To achieve this, no effort is too great.

May 2019 issue of “Insight Lime” published

REMOTE CONTROL

Industry 4.0 also has a significant impact on the lime industry. Although requirements may not be as extreme as insinuated in our cover photo, every lime plant will benefit from the new data mining and processing possibilities. We at Maerz believe, however, that the basis for a successful lime plant is still the lime kiln. Data processing may only assist and optimise kiln operation and overall performance. We expressed this view in a presentation we gave last fall at the International Lime Association’s Information Exchange Forum in Cape Town, which has been reprinted in this issue.

We would also like to introduce a very specific kiln to you, which Maerz built for Schaefer Kalk in Malaysia: this kiln is designed to operate at extremely high temperatures in order to produce a hard burnt lime to be used in very specific products of Schaefer Kalk.

And of course we present a selection of our most recent orders to keep you updated on the worldwide lime industry. We are proud that Maerz has been awarded the largest order in its history regarding kiln capacities: 5 × 800 tonnes per day kilns for Tangshan Gangyuan Metallurgical and Furnace Co., in their Laoting Plant in Hebei province, P.R. China, which is currently under construction and will be commissioned at the end of this year.

OUR KILNS. YOUR NEEDS – OUR SOLUTION.

Every year, more than 300 million tons of lime and dolomite are being calcined world-wide. 
A lot of it in Maerz Kilns.

And we will continue to do so.
