Gypsum industry news

China: Grenzebach BSH, a leading global supplier of process and production technologies, has received a ‘significant’ order from XINFA Group for the supply of two gypsum wallboard lines to XINFA’s existing production plant at its headquarters in Chiping-Liaocheng, Shandong Province. XINFA, one of the world’s leading aluminium manufacturers, will expand its gypsum wallboard production capacity to approximately 830,000m²/day (273Mm²/yr). This will make its plant the world’s largest, and is the second time that XINFA has relied on Grenzebach’s expertise.

XINFA Group runs its own coal-fired power plants to cover the high electricity requirements of its aluminium plants. Flue gas desulphurisation (FGD) gypsum is produced during the purification of the exhaust gases. Using Grenzebach equipment, XINFA has been able to recycle this gypsum to produce gypsum wallboard since 2021.

Robert Brier, CEO of Grenzebach BSH, said “The project demonstrates how close we are to our customers and our competitiveness, as well as our innovative strength in supplying manufacturing plants with a focus on sustainability aspects. By recycling the FGD gypsum, we are supporting our customer’s circular economy, while at the same time using the electricity generated and the waste heat from the power plants to operate the gypsum dryers and systems.”

China: Finland-based Valmet has received an order from Shanxi Qiangwei Paper to supply a machine vision system. The scope of supply includes an IQ Web Inspection System, an IQ Web Monitoring System and winder control with target-stop functionality. The investment aims to improve the operating efficiency and optimise the final paper quality of a paper production line.

Valmet is a global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries. It is based in Espoo.

Shanxi Qiangwei Paper is located in the Shouyang Industry District of Jinzhong in Shanxi province. It mainly produces paper for gypsum wallboard products as well as packaging paper. It has a production capacity of 1.4Mt/yr.

Germany: Gypsum products manufacturer CASEA has ordered a Robotpac type robotic palletiser from Beumer due to increased demand for its products. The new palletiser will be equipped with a fork gripper and a pallet gripping device will be used for handling special product mixtures. Delivery of the order is planned for the third quarter of 2022. CASEA already uses a Beumer palletiser at its Dorste plant in Osterode am Harz, which was installed in 2017.

Kazakhstan: France-based Alphaplatre has won an order to supply a plaster tile production line for Alina. The scope of supply includes preparation and mixing, tile molding, drying and semi-automatic palletisation. No commissioning date has been released.

India: BTL EPC, a division of engineering firm Shrachi Group, has been awarded a US$51m synthetic gypsum, limestone and coal handling equipment contract for Telangana State Power Generation Corporation’s proposed 5X800 MW Yadradri Thermal Power Station Thermal Power Station, according to the Economic Times newspaper. The contract includes the provision of a 21.8km-long conveyor.

India: Bharat Heavy Electricals (BHE) has been awarded the contract to supply emissions control systems, including a flue gas desulphurisation (FGD) system, at the Nabinagar Thermal Power Project. The project is a 4x250MW coal-fired power station being built by Bhartiya Rail Bijlee Company, a joint venture between NTPC and Indian Railways. BHE's scope of work includes design, engineering, civil works, supply, erection and commissioning of wet FGD system along with auxiliaries, including limestone and gypsum handling system and wet stack on a full engineering, procurement and construction basis.

Previously BHE installed a FGD system at Tata Power's Trombay Unit 8 in 2008. Including the latest order, BHE is presently executing FGD systems for 27 units of NTPC and its joint ventures.

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.

India: NTPC has ordered flue-gas desulfurisation (FGD) systems from Japan’s Mitsubishi Hitachi Power Systems for its Mouda-II and Rihand-II & III coal-fired power plants. This is the first order of a limestone-gypsum FGD system for the Indian market, according to JCN Newswire. The installations are scheduled for completion in 2021 and 2022 respectively. No value for the order has been disclosed.

These projects are ordered through MHPS' Indian subsidiary and included engineering, procurement, and construction (EPC) arrangements. The order comprises two 660MW units for the Mouda-II plant, and four 500MW units for the Rihand-II & III plant, for a combined output of 3320MW. The FGD systems will be additional installations to the existing power generating facilities, supporting the design of a spray-type desulfurisation system handled by MHPS' Indian subsidiary.

Germany: Gebr. Pfeiffer says it is planning to use its TRT Triplex dryer to partially calcine gypsum. Testing at the Gebr. Pfeiffer test station has yielded ‘positive’ results and further installations are being considered to explore the concept. The product uses the uniflow principle, where both material and hot gasses flow in the same direction and pass through the dryer tubes from the centre outwards.

The engineering company has received an order for a TRT 5000/8.0 Triplex dryer from Shree Cement in India. The dryer will be used to dry flue gas desulphurisation (FGD) gypsum from a captive coal-power plant for use in cement plants. In the planned dryer plant the moisture of the FGD gypsum will be reduced to a residual moisture of <2%. Artificial gypsum from the dryer will be used at other cement grinding plants in the country. The 50t/hr dryer will be installed at the end of 2018 and is expected to start commercial operation in mid-2019.

UK: Knauf has ordered a second Samson Material Feeder for its Immingham gypsum wallboard plant. The 100t/hour feeder is to be supplied in October 2017 and it has a centre distance of 11.7m. Knauf is extending an existing raw materials reception area, where products arriving by truck are transferred directly by the feeder to an ongoing conveyor to the production facility.

The Samson Feeder presents an alternative to fixed bunker constructions and can receive bulk materials directly from diggers or dumper trucks. The wide conveyor belt design allows a very low loading height so that trucks can discharge directly into the entry section of the unit. Therefore the bulk material can be unloaded and transferred to the plant straight away, with no requirement for interim storage on arrival. If continuous discharge to an ongoing conveyor is not required at any given time, the bulk material can also be stored in the Samson unit.
