Detailed Description

Spiral Classifier tanks are engineered to provide the most effective pool area and overflow velocity requirements. By combining the proper submergence of the Spiral with one of the tank designs, a wide range of combinations is possible. (Refer to table on the last page.) The proper combination of pool depth, area and Spiral construction results in controlled turbulence for accurate size separations, efficient washing and/or dewatering as required. Spiral Classifiers can be tailored to suit your needs. Spiral ConstructionPre-formed sectionalized steel flights form a continuous Spiral helix. Spiral Classifiers utilize an increased lead or helix angle to form the continuous high pitch Spiral for greater raking capacity.Manual and Hydraulic Spiral Lifting DevicesTwo options are provided.A manual handwheel for raising and lowering of Spiral assembly by a simple positive action, handwheel operated screw device.Manual lifting arrangement are usually provided with smaller size range.Alternatively, spiral assembly can be raised and lowered by a Hydraulic system.
