Austria/Canada: Canada-based Solex Thermal Science has been selected by Austria-based Cemtec for a mineral cooling project based in Central Europe. As part of the agreement, Solex will deliver a customised plate-based moving bed heat exchanger (MBHE) that will be used to indirectly cool a milled, mineral-based powder that’s similar to cement. The unit is expected to be delivered by the summer of 2022.

Solex says that the use of a welded plate-channel design allows the powder to flow by gravity within a vertically orientated exchanger and between banks of stainless-steel plates. A heat transfer fluid passes within the plates to cool the material by conduction. The use of indirect heat transfer technology, combined with customised plate spacing, provides the necessary residence time to eliminate caking within the unit while also ensuring consistent temperature profiles at the outlet.

“We are excited to bring our decades of thermal engineering experience to this collaboration with Cemtec,” said Gerald Marinitsch, Global Director, Industrials for Solex Thermal Science. “We are confident that our MBHE technology will provide a reliable, real-world solution to this unique and important cooling application.”

Cemtec is a specialist in providing wet and dry grinding technologies for many types of bulk materials and minerals including the cement sector. Solex Thermal Science develops indirect heat exchange technology for the heating, cooling and drying of free-flowing granular materials such as solid granules, pellets, beans, seeds and particles.

Germany: Cemtec has successfully transported a 170t cement grinding mill from its headquarters in Enns, Austria to a client in Bavaria. The transported equipment had an internal diameter of 4.6m, an outside diameter of 5.2m and a length of over 17m. Due to the size of the mill the transportation could not be carried out on motorways and the engineering company was forced to use smaller roads and inland waterways include the River Danube. Extra challenges included using additional haulage vehicles to cope with inclines of up to almost 14%, temporarily removing electricity and telephone cables in certain locations, laying road slabs at crossroads and shutting a motorway while the mill crossed it. The total transportation time took eight days.
