Gypsum industry news

UK: Langley Holdings, owner of Claudius Peters, recorded consolidated sales of Euro1.17bn during 2022, up by 40% year-on-year from Euro815m in 2021. The group ended the year with an order backlog worth Euro900m. Its Other Industrials division, which includes Germany-based Claudius Peters, recorded sales of Euro277m, up by 11% from Euro250m. Langley Holdings said that, due to the length of its lead times, Claudius Peters’ profitability was especially impacted by costs rises in its delivery on existing contracts in 2022.

Chair Anthony Langley said “Hopefully management will make progress with tangible improvements to the plant machinery business: restructuring is not the preferred option, but, either way, I do expect a better result this year.”

Egypt: Dahab Sinai says that it has commenced pilot production at its 0.18t/yr plaster plant in the Suez region. The company invested around US$18m in building the unit. In early 2019 it was reported that Dahab Sinai ordered a gypsum production plant from Germany-based Claudius Peters. Rowad Tourism holds the 64% majority stake in Dahab Sinai.

Egypt: Dahab Sinai for Manufacturing and Building Materials has ordered a gypsum plant from Germany’s Claudius Peters to be built in the Suez region. The new plant will be used for the production of basic plaster for wall and ceiling plaster products. Construction is scheduled to start in early 2020 with commissioning to follow in the the third quarter of the year. No value for the order has been disclosed.

Claudius Peters will supply a grinding and calcining plant with a EM47 type mill with a stucco throughput capacity of 25t/hr. A homogeniser for product optimisation is connected behind the calcining process. After the cooling process the produced basic gypsum can be adapted to the market requirements by adding setting regulators and hydrated limestone. This part of the plant is also included in the scope of supply. The finished product is bagged by means of a four spout packer RotoFill type R6/4L with a capacity of 1137bags/hr. Various silos, a truck loading and unloading plant, the complete electrical equipment and control systems as well as the raw material handling with corresponding conveying technology are also part of the delivery.

The new plant will be used to supply the local market but exports to Africa and Europe are also planned. The plant is designed in such a way that further plant equipment can be installed at a later stage. The mixing plant can be extended with the admixture of further additives. Furthermore, a reserve space for the later retrofitting of a bag applicator with loading equipment has been taken into consideration.

Germany: Claudius Peters’ has launched an upgrade to its Rotary Drum Cooler (RDC) that is intended to low energy costs and includes new features. The product operates on the counter-current indirect principle re-using cooling air as preheated combustion air for the hot gas generator, with a reduction in plant energy costs. During the cooling process, the RDC enables homogenisation of materials, with reduction of unwanted calcining by-products such as soluble anhydrites and dehydrates. The cooler can handle up to 100t/hr of product.

“We are proud to have been supplying the gypsum industry with cutting-edge products for more than 20 years. Our Rotary Drum Cooler deploys state-of-the-art technology to maximise plant efficiency by reducing maintenance and energy costs,” said Claudius Peters’ managing director Reiner Fruehling.

Other features of the RDC include trunnion bearings, central axis feeding and discharge, aeroslide feeding and discharge, variable speed motor for soft start-up, improved automatic lubrication system and optional inlet housing for external cooling air.

Sweden: Gyproc Saint-Gobain has commissioned a new Claudius Peters type EM 65-592 grinding and drying mill, to be installed at its Gyproc Balsta plant.

The project, which includes dismantling of the existing mill and erection of the new one within a six-week time frame, uses Claudius Peters' newly developed hydraulic tensioning system for adjustment of grinding pressure. This system, installed here for the very first time, has been specially developed to optimize the efficiency of the grinding and drying processes and also to aid maintenance.

"This new EM drying and grinding mill, representing the very latest in technology from Claudius Peters, delivers unprecedented levels of efficiency and precision. We are delighted to be partnering with Gyproc Saint-Gobain in this project," said Stephan Oehme, sales director for Claudius Peters.

Commissioning of the new mill is planned for the middle of July 2016.

Sweden: Gyproc has awarded a contract to Claudius Peters Projects for the supply of a gypsum grinding and drying mill type EM 65-592. The mill will be installed at the Gyproc Balsta plant in Sweden. The contract was signed in October 2015.

The scope of supply includes the dismantling of the existing mill as well as the supply and erection of a new mill, including all connections to the existing periphery. A special challenge for this project is the tight schedule for the dismantling and erection of the equipment, within six weeks. Additionally, Claudius Peters Projects' newly-developed hydraulic tensioning system to adjust the grinding pressure will be installed for the first time.

Commissioning is planned for middle of July 2016.

Czech Republic/Germany: Claudius Peters has been awarded a contract from a German-Czech consortium for the delivery of a gypsum calcining plant with a capacity of 12.5t/hour for installation at a Czech power plant. Commissioning is planned for the beginning of 2016.

The scope of supply comprises a HIC (Horizontal Impact Calciner) to calcine flue gas desulfurisation (FGD) gypsum which has been ordered for the first time. The HIC has especially been developed for the calcination of synthetic gypsum. The material is further conditioned in a homogeniser with a capacity of 12.5t/hour. The material will be transported in tankers to Germany for further processing. This is the sixth homogeniser supplied by Claudius Peters.

Bulgaria: Bulgarian building materials maker Gips has launched a Euro8m factory for the calcination of natural gypsum in the north-western province of Vidin. Company officials announced that the new factory has a capacity of 80,000t/yr and has improved energy efficiency by 38% compared to the old factory.

Bulgarian construction company Montagengineering built the plant and the equipment was supplied by Germany's Claudius Peters Projects. The project was co-financed with Euro1.8m from the European Union funded operational program 'Competitiveness' while Gips provided the remainder from own funds.

Gips, Bulgaria's sole producer of natural gypsum, was set up in 1965. It intends to boost its exports, as it currently sells some 90% of its output on the domestic market according to its executive director Plamen Vassilev. The company currently exports to Serbia and is considering entering the Romanian market. The new factory and the company's nearby gypsum mine employ a total of 224 people.

Vietnam/Indonesia: Lafarge Boral Gypsum Asia, soon to be wholly-owned by Boral, has awarded a new contract to Claudius Peters Projects GmbH Germany for two gypsum calcining lines with a capacity of up to 30t/h to expand its gypsum wallboard production in Asia.

In Vietnam a fully-integrated line will be installed at the site of Lafarge Boral Vietnam Gypsum Co. Ltd near Ho Chi Minh City, extending the capacity of the current wallboard production line. The second line will be installed in Indonesia and will be part of an extension programme of the Cilegon installation of PT Petrojaya Boral Plasterboard.

Both of the lines consist of a Claudius Peters Mill EM59-585 along with the auxiliary equipment and controls of a complete raw material handling, gypsum calcining and cooling system.
