Austria: Loesche subsidiary A TEC has won a contract for the supply and installation of a Flash Dryer for alternative fuels (AFs) in the kiln line of Lafarge Zementwerke's 1.1Mt/yr Mannersdorf cement plant in Lower Austria. The supplier said that it will complete the project in early 2021.

The company said, “Reaching high thermal substitution rates (TSR) requires firing of alternative fuels at the kiln burner. To reach a stable sintering zone for the required clinker quality a high fuel quality (high LCV, small particle size) is needed, otherwise the clinker quality may suffer or the TSR can be limited. With the A TEC Flash Dryer various waste heat sources can be used (clinker cooler flue gas, bypass gas, preheater gas, etc.). The material is dosed to the hot gas flow in the flash dryer and transported with this gas flow, while the moisture is evaporated, to a cyclone and a subsequent filter where the fuel is separated from the gas flow and on-line fed to a kiln burner or a satellite burner. In addition to the drying the lifting effect of the gas can separate 3D impurities which contributes in a further increase of the fuel quality.”

South Korea: Austria's A Tec is installing two RM 2.50 Rocket Mills at Ssangyong Cement’s plants in Donghae and Yeongwol. The mills will be used to shred municipal and industrial waste to produce solid alternative fuels for use in the plant’s kilns. No commissioning dates have been released.

Austria: A Tec has launched a mobile version of its grinding mill. The semi mobile A Tec Rocket Mill 2.00 single is a compact version installed in a container. The mill consists of one grinding chamber with approximately a 2m diameter and 315kW installed power at the main drive. This will give roughly the half capacity of the double chamber Rocket Mill 2.50. The throughput when producing refuse derived fuel (RDF) for the main burner (90% < 50mm) is about 10 - 12t/hr.

Austria: A Tec has commissioned a Rocket Mill RM 2.50 for ASA at its waste treatment plant in Wiener Neustadt. The mill has a capacity of 7 – 40t/hr and is equipped with two grinding chambers, which can be independently loaded. Each one has a main drive with 315kW. Due to the grinding technology, it also has an additional drying effect of approximately 10%. The mill is designed to produce refuse-derived fuels (RDF) with an output size of 5 - 80mm from pre-sorted and shredded household and commercial waste. It was principally built at A Tec’s plant in Eberstein.
