Vacuum Ceramic Filters

Our Vacuum Ceramic Filters are used widely for dewatering iron ore slurries in mining industry. The scale of iron production processes is typically very large which means that small changes in the operation of the filter can have a significant impact on the overall effectiveness of the process. Some of the variables that determine the performance of ceramic disc filters are the rotation speed of the disc, the level of slurry in the feed basin, the vacuum level applied during the filter cake formation and dewatering stages and the solid concentration as well as the temperature of the feed slurry.

Vacuum Ceramic Filters are used to dewater a wide variety of different kinds of mineral concentrates in the mining industry. The construction and operation principle of ceramic disc filters are pretty similar to the conventional disc filters but the difference is that the filter cloths are replaced here by microporous ceramic segments. As these segments are immersed into the slurry under vacuum, the filtrate is drawn through the ceramic elements and the filter cake forms onto the external surfaces of those. When the segment rises from the slurry basin, the dewatering of the filter cake begins due to the
vacuum that continues to draw the liquid from the cake into the segment. The moisture content of the cake decreases until the vacuum is broken and the cake is discharged by a scraper.
