Coupling opposing sets of counter rotating weights with a gearset, the proprietary eccentric weight vibrators either add together or cancel the reactive centrifugal force based on the angular position of the weights. The result is a straight line, vibratory force that can be easily oriented, scaled up in size and/or combined to process a diverse range of foods, chem- icals, pharmaceuticals, minerals, plastics and other products. Included as standard equipment on the company's line of vibrating fluid bed dryers, coolers, screeners and plastic pellet classifiers, the vibration technology establishes a gentle, first-in, first-out conveying action that effectively moves the product downstream in a controlled, uniform manner. Developed and manufactured at the company's Washington, N.J., headquarters, the vibrators are installed and tested prior to delivery and are backed by a full warranty. The Witte Company Inc., Sturtevant Mobile Air Classifying Plant Removes Excess Fines The Whirlwind Mobile Air Classifier from Sturtevant Inc. is the world's first and only 100-percent mobile air classifying plant with integral collapsible conveyors, according to the company. The Whirlwind Mobile Air Classifier effectively removes excess fines from aggregate products bringing materials formerly considered waste materials into specification. The Mobile Air Classifier's dry separation process eliminates the need for water typically used in washing plants, which is especially important in remote areas where water is not readily available. The Whirlwind Mobile Air Classifier is easy to transport with a rugged chassis frame and a heavy-duty, tri-axle suspension. The Whirlwind Mobile Air Classifier has three conveyors that hydraulically fold for transport and unfold for set-up. Raising and lowering of the air classifier is accomplished with heavy-duty dual hydraulic cylinders for easy and safe set-up and tear down. The company also offers the Side Draft Air Classifier, a highly versatile, energy-efficient system for the consistent sepa- ration of particles in the 100 to 400 mesh range; and the SuperFine Classifier, for achieving the high degree of accu- racy demanded in the separation of particles 45 microns and smaller. Ideal for separation 45-3 microns. Sturtevant Inc., Witte Equipment Features Proprietary Vibrating Technology
