Summary

Solid-liquid separation of ceramic powders by thin-cake filtration offers advantages over conventional cake filtration. The dynamic mechanism limits cake growth, creates a permanent precoat, and produces a thick paste discharge. Features of the technology include continuous operation, uniform product quality, high separation efficiency, and superior washing capability. Practical design provides complete isolation of process fluids from the environment, protecting operators and ensuring product purity. Separation and washing of silicon carbide, soft ferrite, and orthotitanic acid is accomplished batchwise and continuously, and represent a savings in processing time and water consumption when compared to conventional filter presses.
