Romania: Holcim Romania has successfully upgraded pyroprocessing and cement grinding equipment at its Câmpulung cement plant in Argeș County. Germany-based KHD Humboldt Wedag supplied equipment for the upgrade. For the plant’s pyroprocessing line, this included a downcomer duct, water injection system and induced draught fan, as well as an upgrade to the clinker cooler. Meanwhile, the grinding line has received a new SKS Z 2500 dynamic separator, cyclones, process ducts and separator fan. The supplier says that the upgrade has increased the Câmpulung plant’s clinker capacity and the efficiency of its operations. The work took 14 months to complete from the signing of the contract in mid-2023.

Sweden: Germany-based KIMA Process Control has secured a contract for the supply of a kiln shell cooling system for Cementa's Slite cement plant in Gotland. 88 water jets will deliver centimetre-precision cooling for the 55m-long kiln, while IR pyrometers measure temperatures over areas of 10cm². According to KIMA Process Control, the equipment can avoid unnecessary cooling of the kiln shell, conserving the heat energy supplied by the main burner.

The new cooling system will eliminate the use of energy intensive electric fans, slashing 1700t/yr in CO₂ emissions, according to the supplier. It said that noise emissions will also 'drastically' decline as a result of the upgrade. The system's operating costs are reportedly 98% less than those of the plant's existing fan system.

The supplier said that the new equipment will 'bring the cement plant in Slite an economic benefit in the shortest possible time.' It said "For the cement industry, this project represents a new milestone in terms of best available technology in the operation of rotary kilns."

Pakistan: Germany-based Menzel Elektromotoren has revealed work on a replacement motor it has built for an unnamed cement plant in Pakistan. As part of the project it has designed a motor to fit a limited installation space that could drive the unit’s raw mill, another cement mill or a fan.

The engineering company’s solution was a compact slip ring motor in frame size 710 with the cooling system tailored to fit around a steel girder in the cement plant. To accommodate the existing couplings in two different sizes, Menzel designed the replacement motor with two shaft ends with different diameters. The motor output is configured to ensure efficient continuous operation in each of the three applications. The machine has a rated output of 4600kW and a rated voltage of 6300V. It complies with protection class IP55. At the customer's request, it was designed in cooling type IC 666, with permanent external ventilation of the inner and outer cooling circuit. Before delivery, Menzel also ran a load test in its in-house test field with the end-user attending via video streaming.

Germany: Australia-based FCT Combustion has successfully delivered a new Turbu-Flex burner to replace the existing burner at HeidelbergCement’s Hanover, Lower Saxony, cement plant. FCT Combustion will also supply burner accessories and add-ons, an igniter, a flame sensor, fans, blowers and spare parts. The project aims to improve combustion control and maximise alternative fuel (AF) use in the plant’s cement production.

Uzbekistan: Germany-based IKN has secured a contract for process integration and equipment design for a new kiln line at Qizilqumsement’s Qizilqumsement cement plant. The supplier’s remit includes the pyroprocessing line, preheater, kiln and cooler including ID fan, kiln drive and burners. It plans to use a six-stage preheater, the region’s first. Commissioning is scheduled for 2022.

Austria: Germany-based Loesche has received an order to supply a new raw materials grinding plant to LafargeHolcim subsidiary Lafarge Zement’s Mannersdorf cement plant. The plant will consist of a type LM 45.4 mill, a LSKS type classifier, a rotary feeder, a magnetic separator, a conveyor, a pair of Hurriclons, a mill fan and the ‘Digital Ready 4.0!’ digital package. Loseche’s subsidiaries Kingsblue and AixProcess are responsible for the digital products and A-Tec for the Hurriclons. Commissioning is scheduled by the end of February 2022.

Cement and ore head of sales Stefan Baaken said, "Many cement plants in Europe are facing similar challenges to our customer in Mannersdorf. For us as an original equipment manufacturer and also for the customer, the new grinding plant is an important signpost towards more energy-efficient and sustainable cement production.”

Germany: Pollrich has acquired the fan product range and trademark of Rußwurm Ventilatoren. The latter company registered as insolvent in late 2018.

Following the takeover, Pollrich says it has become a leading supplier of heavy-duty industrial fans and has consolidated knowledge in the field. Customers will be able to continue to buy fans and spare parts for Ruwu and Meissner+Wurst products. Former company director Hans Jörg Rußwurm will remain the lead contact for queries regarding the takeover and the product range at a new sales office at Meitingen, Bavaria.

Bulgaria/Panama: Germany’s Venti Oelde has increased its sales presence in Europe and Central America. Its has appointed a new sales representative in Bulgaria, as well as one in Panama to cover countries including Mexico, Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. The company manufactures industrial products including fans and filters.
