IAC patented a state-of-the art, single flow, Dual Feed rotary dryer; which greatly reduces the complexity of controls found in fluid bed or counter-current rotary dryer designs. The system leverages the inherent material characteristics to speed processing.---------- A partial amount of moist sand feed material is added into a second dryer inlet and blends with the dried, but as yet uncooled product. Evaporation of water from the moist material assists cooling of the remaining dried solids. The heat from the dried solids is used for drying the partial add-in quantity of moist sand. The entire energy consumed for heating the dryer, as well as the entire amount of air for drying and cooling are significantly reduced. --------- IAC’s smallest patented frac sand dryer technology has proven to process wet sand with 8-10% moisture at a rate over 100 TPH, 5-6% moisture at 160+ TPH and over 250 TPH with 3-4% moisture. This gives frac sand plant owners options to streamline the flow of production from sand to silo.
