The motion of the particles was analyzed. The effects of vibration amplitude, throwing index, and screen deck inclination angle on the screening process are discussed.,Vibrating Screen Working Principle,The simplest Vibrating Screen Working Principle can be explained using the single deck screen and put it onto an inclined frame. The frame is mounted on springs. The vibration is generated from an unbalanced flywheel. A very erratic motion is developed when this wheel is rotated.,Influence of vibration mode on the screening process,The screening processes used either a linearly, circularly, or elliptically vibrating screen at a vibration frequency, amplitude and screen-deck inclination of 14 Hz, 4 mm, and 3°, respectively. The non-normal value of the inclination for circular vibration of the screen-deck as adopted for comparing the three different modes is shown in Fig. 3 .
