Our process revolutionizes filter-cake processing, turning an outdated process into a model of efficiency. ZMax SAP is mixed and blended with coal filter cake, using a pugmill (such as the COALCAKEpug pugmill system by PavementGroup). Filter cake is very clumpy and wet as it discharges from the coal plant. Our process allows for a steady stream of filter-cake to feed into the pugmill at a continuous rate, tailored to the customers needs.
