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.
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.


December 2017 issue of “Insight Lime” published


We selected the subject of this Insight Lime’s title page for a very good reason: Maerz successfully completed two projects in regions known for their deserts: the new lime plant for Astra Mining Company south of Riyadh in Saudi Arabia and a new kiln for Baslimane Chaux Berriane in central Algeria. We further received an order for a kiln located at the eastern end of the Thar Desert in Rajasthan in India. Maerz also has a lime kiln project for Uni Lime in El Mohandessin in Giza close to Cairo in Egypt. Dry and hot? No problem.

Since October this year, Maerz is able to offer a completely new product line: with the integration of Elex CemCat AG we supply in our new business unit “CemCat” Selective Catalytic Reduction (SCR) plants for NOx emission control in the cement industry. A major turnkey SCR-installation for Schwenk Zement KG’s plant in Karlstadt, Germany, is currently in progress and will go into operation in early 2019.


As reported in our April 2016 issue of Insight Lime, the Algerian company BCB Baslimane Chaux Berriane placed an order with Maerz for a 300 tons per day natural gas fired Maerz PFR kiln of type E5, including the up- and downstream plant equipment. The dolomite plant is located in Berriane, an area featuring one of the world’s top class dolomite deposits, which is the reason why BCB decided to modernise its existing plant featuring a small rotary kiln.
One of the technical challenges of building a kiln in the centre of the desert is the extremely high temperature in the Algerian summer, requiring appropriate adaptations in the kiln process design.
The kiln was lit up in September this year and is now in full industrial operation.


Saudi-Arabian Astra Industrial Group (AIG), a leading industrial conglomerate, which is active in the key industrial segments of pharmaceuticals, specialty chemicals, power & steel and mining, decided some years ago to extend its product portfolio by products related to limestone and burnt lime as well as hydrated lime. Hence Astra Mining Company Ltd LLC was founded in 2011 as a joint venture between AIG and Tharawat Mining, to set up a completely new lime plant in the aspiring Al Kharj Industrial Zone, approximately 100 kilometres southeast of Riyadh.
The plant is laid out nearly in a single line to allow a cookie-print-like repetition of this design for future kiln lines. First, an order was placed with Maerz for the supply of engineering, know-how and design as well as for key equipment for a 300 ton per day Maerz PFR kiln of type R1P fired with natural gas. In addition, Maerz supplied engineering and key equipment for a 12 ton per hour hydration plant.
The kiln was lit for the first time in May 2017 and has constantly been producing high quality quicklime since then.


India, with its large industry has a huge demand for lime. Whereas in the steel industry the required lime is mostly produced in modern captive lime plants, the major part of India’s commercial lime is still produced in small traditional field kilns. The limited availability of limestone suitable for calcination leads to a concentration of the industry in two major regions: Central India and Rajasthan.
Subaan Lime is changing the game now in northern Rajasthan, where it entrusted thyssenkrupp Industries India Pvt. Ltd. from Pune, Maharashtra, together with Maerz Ofenbau AG, with setting up an entire new lime plant with a production capacity of 300 tons per day of quicklime.
Subaan Lime already operates a quarry, supplying limestone to smaller lime producers in the area. By investing in the new plant, Subaan Lime is not only increasing the overall lime production capacity in the area, but is also taking environmental responsibility by reducing emissions using state-of-the-art production technology. Furthermore, Subaan Lime has underlined its responsibility for the environment by planting numerous trees on the new factory site.
With Maerz contributing the technology and design of the 300 tons per day petcoke dust fired Maerz PFR lime kiln of type E5, thyssenkrupp Industries India will design the entire greenfield lime plant, supply the equipment to Subaan Lime and perform the erection of the new facility. The plant is scheduled to become productive in late 2018.


voestalpine Stahl GmbH, domiciled in Linz, Austria, operates a lime plant with four Maerz PFR kilns in Steyrling, some 60 km south of Linz. The lime produced in Steyrling is used for voestalpine’s own steel plant in Linz. Recently, voestalpine signed a contract with Maerz Ofenbau AG for a turnkey project for a 300 tpd natural gas fired R1P Maerz PFR lime kiln. The new kiln is going to replace an obsolete kiln, which went into operation in the early seventies.
Please click on “Newsletter 2017/12” above for more technical layout details of this project.
Maerz’s equipment supply comprises:

  • Kiln charging system
  • All components for the kiln steel structure
  • Refractory lining
  • Process air blowers with motors
  • Firing system for natural gas
  • Hydraulic equipment
  • Waste gas dust cleaning system
  • Lime discharging system
  • Electrical, measuring, control and visualisation systems
  • Spare parts for commissioning and two years operation.

Cold commissioning will take place in exactly one year from now and the kiln will be lit before Christmas 2018. We look forward to taking on this challenge and successfully completing this project.


Chememan Co., Ltd. of Thailand and Maerz Ofenbau AG signed a contract for the installation of another Maerz lime kiln.
Chememan, a mineral and chemical company, with its headquarters in Bangkok, Thailand, was founded in 2003 and is now a recognized leader in the Asian lime industry. As a fully integrated producer of lime and lime-related products, Chememan aims to reach an annual production capacity of 1 million tons by 2020, which would place it among the top 10 lime producers in the world. At present, Chememan operates four Maerz lime kilns in the Saraburi area. The recently ordered new kiln of the rectangular PFR type E5 has a nominal production capacity of 300 tons per day of burnt lime and will be fired with coal and/or lignite dust. The kiln will process limestone from Chememan’s Tubkwang/Saraburi quarry with varying stone gradings between 20 and 120 mm and relevant kiln outputs from 220 up to 300 tons of lime per day.
For the new kiln, Maerz will supply engineering, license and know-how as well as the following materials and equipment:

  • Process air blowers with motors
  • Firing equipment for coal dust (hard coal and lignite)
  • Hydraulic equipment
  • Electric, measuring and control equipment
  • Limestone skip hoist winch.

Maerz will furthermore supply technical advice and assistance services for commissioning and start-up of the lime kiln plant, which is due for commissioning during the first quarter of 2018.


After ordering their first Maerz PFR lime kiln in 2014, DAESUNG MDI (Mining Development Inc.), Yeongwol-gun, Gangwon-do, Korea, placed an order with Maerz Ofenbau AG for the installation of a second Maerz PFR kiln. Within the scope of the new contract Maerz will supply engineering, license, know-how, material and equipment as well as technical assistance services during erection, commissioning and start-up for the 300 tpd solid fuel fired E5 Maerz lime shaft kiln.
The new kiln will process limestone with variable limestone gradings, such as 25 to 55 mm, 40 to 80 mm or 55 to 100 mm and will produce between 200 and 300 tons of lime per day. A solid fuel mixture, consisting of bituminous coal and anthracite will be used as fuel.
The customer will engage local contractors for the erection of the kiln and the lime plant with all related auxiliary equipment. Maerz will provide technical assistance services during start-up and commissioning of the kiln plant, scheduled for the second half of 2018.

GENUINE SWISSNESS. As most Swiss, we don’t like to push ourselves into the limelight. We are content knowing that we are well-known and our kilns are in demand throughout the world. To date we have built more than 600 plants for customers in over 60 countries. To make our customers happy we gladly go the extra mile.
That’s genuine Swissness.


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

For over 3000 years, burnt lime has been a basic material in the construction business. Today, it is also an important component for the chemical industry, agriculture and especially for the steel industry. Maerz kilns calcine the largest share of the amount needed worldwide – more than kilns from any other manufacturer. There are good reasons for the success that Maerz kilns enjoy: Highest efficiency. Lowest energy consumption. Broad range of kiln types. Individual solutions depending on location, raw material and available fuel. Maerz’ portfolio comprises all modern kiln types.

WHY SO MUCH OF THE WORLD’S LIMESTONE IS BURNT IN MAERZ KILNS. For over 60 years we have been passionately devoted to the technology of Iimestone calcination. A technology, which we have continuously enhanced. With the result that today a large portion of the burnt lime produced worldwide comes from our customers. For their success we always go the extra mile.
And we will continue to do so.


Maerz’ customer service operates just as impeccably as its kilns do. Globally.

Maerz supports its customers in different ways – anytime, fast and everywhere. Also after the commissioning of a turnkey plant. These are the services Maerz offers:

NO STONE IS LIKE ANOTHER. NO CUSTOMER EITHER. We have only become the world’s number 1 for lime kilns because each customer is our number 1. Whatever our customers’ request, we always see it as an opportunity to better ourselves. Therefore we work a little harder than necessary, from our offer to our servicing, to keep our customers satisfied.
That’s who we are.
