Grain rotary screen rotary drum vibrating screen manufacturers direct
Swing screen is a high efficiency screen machine for grain rotary screen and rotary drum vibrating screen produced by Xinxiang Dayong Vibrating Equipment Co., Ltd.Stable screen motion even under full load.Tumbling movement indefinitely adjustable, resulting in precise control of residence time on the screen, capacity and screening efficiency can be coordinated and optimized.Product specific mesh cleaning systems.
Because of the motion trajectory of the griddle box, the Tumbler screen machine is also called compound circle screen. The vibration force produced by the drive system is a kind of inertia force which is circling the dead axle and changing regularly. Intrinsically, it is a kind of centrifugal force given by the eccentricity mass circling around the dead axle. The sieve is ususlly installed horizontally or with tiny angle(0°-5°). The principle is:when you start the machine, the vibrating part —the screen box takes circling motion under the influence of the vibrating force.The screen box drive the sieve to take circling motion periodicity,so the material on screen surface take bounce motion, meanwhile, the material less than the aperture drop to the next deck,and the oversize are discharged by the outlet.Finally ,the screening work is completed. From the aspect of its structure and working principle, the exciter can circumgyrate in two ways according to the motion of the material, uniformily or contrarily. As a result ,we’d better make a choice between throughput and efficiency according to our practical demand.
