Abstract
It is established that, at OAO ZSMK, the moisture content in the flotational concentrate is reduced by 4.5% when dehydrating the cake using Andritz vacuum filters rather than Ukraina-80 filters. The content of solid matter in the filtrate is reduced by a factor of four. Extraction of large-grain slurry from the supply to the vacuum filters is more complete, with corresponding reduction in the content of >0.5 mm classes (by 4.1%) and 0.06–0.50 mm classes (by 1.8%) in the filtrate. The loss of final product with the filtrates is reduced by 0.3%; the total power consumption of the vacuum-pump drives is reduced by 826 kW.
