W.S. Tyler says its new Hydro-Clean washer effectively cleans industrial minerals, aggregate and other materials while reducing water consumption by up to 75% over traditional log washers. Taking a maximum feed material size of up to 6 in. (150 mm) into its vertical drum, the Hydro-Clean employs high-pressure nozzles, rotating at 90 rpm, to spray up to 90% recycled water on the material with pressures up to 2,900 psi (200 bar). The washing unit removes silt and clay particles as small as 63 microns from mineral mixtures and, with short retention times, can process up to 400 t/h, depending on model size and application. The distance between the washing rotor and the material bed in the Hydro-Clean is variable and allows the system to adapt to various material types. Level sensors located at the material feed inlet provide exact data to the PLC control unit, ensuring a consistent material flow into the system. Due to its compact size and weight, overall operating and structural costs are considerably lower than with traditional washing systems—which also require more equipment and a larger footprint. While a traditional washing system can require up to three screens along with a log washer or screw, the Hydro-Clean only needs an additional wash screen for its discharged material. Water consumption ranges from 27 to 211 g/min, depending on application and model size, while power requirements don’t exceed 300 hp (225 kW) even for the largest model.
