Paraguay: Cementos Concepción (CECON) has started commissioning its new plant at San Lázaro in the Concepción department by grinding raw material. Alexander Gonzalez, the project manager for the plant, told La Nación newspaper that start-up of the unit had been successful and that the process would now continue along the production line. The plant’s kiln is expected to start operation in October 2022.

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: Christian Pfeiffer has launched its new FlexCore hardened rolled steel plates for ball mill diaphragms. With a hardness of 60HRC, the plates are wear and breakage resistant, enabling maintenance to be planned to the day, according to the supplier.

Latvia: Germany-based Christian Pfeiffer says that it has successfully commissioned the new Broceni grinding plant for Schwenk Latvija. The supplier said that the plant is able to produce cement up to a fineness of 5600 Blaine and is one of the most sustainable grinding plants in Europe.

Schwenk Latvija previously announced a planned investment of Euro34m in a new 170t/day mill and a 12,500t silo at the site of its former Broceni integrated cement plant.

Asia: FLSmidth says that it has won a contract to supply its low-NO_x ILC preheater, an OK raw mill, an OK cement mill and other equipment to a cement plant in Asia. FLSmidth will deliver the equipment in 2023. The total value of the deal is US$56.1m.

FLSmidth’s cement industry president Carsten Riisberg Lund said "This project showcases FLSmidth’s ability to deliver energy efficient technologies across the full cement flowsheet, and thereby support our customers in both increasing capacity and their sustainability efforts.”

Azerbaijan: Turkey-based Dal Machinery & Design has successfully delivered a ball mill and drive set to Holcim Azerbaijan’s Garadagh cement plant. The supplier says that the equipment will serve cement grinding operations at the plant.

Pakistan: Fauji Cement has ordered three MVR vertical roller mills from Germany-based Gebr. Pfeiffer for its upcoming Salar cement plant in Dera Ghazi Khan/Punjab Province. The supplier says that the order consists of a 520t/hr MVR 5600 R-4 mill for grinding raw materials and two 180t/hr MVR 5000 C-4 mills for cement grinding. China-based Hefei Cement will handle the order.

Zimbabwe: Germany-based Gebr. Pfeiffer says that a new MVR 3070 C-4 mill for cement grinding is due to be commissioned at Holcim Zimbabwe’s integrated plant at Manresa near Harare. The order was handled by the Chinese contractor CBMI.

The roof at the plant collapsed over a cement mill in October 2021 leading to a reduction in production volumes at the plant. The mills were restarted in February 2022 but one of the one of the existing cement ball mills was decommissioned. This mill is being replaced by the new vertical roller mill supplied by Gebr. Pfeiffer. It is expected to double the plant’s cement production capacity after it is commissioned in the second quarter of 2022.

Zimbabwe: Lafarge Zimbabwe’s cement volumes fell by 55% year-on-year in the first quarter of 2022. The company restarted grinding units at its Manresa grinding plant in February 2022 following a roof collapse in October 2021. In a trading update, Lafarge Zimbabwe said that the disruption impacted its profit in the quarter. The producer took the opportunity to decommission one of its ball mills for replacement with a new vertical roller mill in mid-2022.

Chief executive officer Geoffrey Ndugwa said “The company is confident that volumes will recover and grow as the availability of cement stabilises, especially after the new vertical roller mill start-up in the second quarter of 2022.”

US: Drake Cement & Materials has inaugurated a new finish mill at its integrated plant at Paulden in Arizona. Chief executive officer Enrique Rozas and Ricardo Rizo Patron, the chairman of parent company Skanon Investments, attended the event. Drake Cement & Materials is a subsidiary of Peru-based UNACEM.
