The rectangular screeners are equipped with two vibrating motors rotating in opposite directions. This dual motor configuration causes the screens frame to vibrate in a linear or straight-line motion perpendicular to the plane of the motors. Normally, the motors are positioned at an angle of 50 degrees respect to the screens surface. This result in excellent forward conveyance of oversize particles , even when the screens frame is in an uphill position. Depending upon the application, the screens frame can be position from 10 degrees up to 15 degrees of inclination. Maximum capacity is achieved in the uphill position, causing the formation of a pool at the feed end of the machine. The head or pressure from the pool increase fluid throughout. The rectangular screens conveys the oversize particles out of the pool area where they are then discharged. When two vibratory motors of the same frequency are fixed to a rigid common base, which is freely suspended, or supported and run in opposite directions to each other, they automatically synchronize to produce a straight line motion. The rectangular screens can be adapted by the factory to meet special requirements regarding plant layout and environmental constraints. The rectangular Vibrating Screens are frequently manufactured in various grades of stainless steel for the chemical industry and protected by special painting systems for severe conditions in the mining industry.
