Description:

　　The self-fixed center vibrating screen is used for coarse, middle and fine screening of ores & coal etc. It can be used also for cement and medium removal in materials. This kind of screen is mainly composed by screen box, exciter and hanging (support) device and motor.

　　His another name is universal hanging screen which is vibrated by eccentric vibrator. It has the following properties: 1). Materials on the sieve can be well loose and layered under the vibrating action; 2). Counterweight of screen can be adjusted, and according to production rates to adjust the vibration amplitude; 3). Amplitude changes on basis of feeding rate. When the feeding rate is small, the amplitude increases, conversely the feeding rate is larger, the amplitude decreases. The feeding rate change will impact the “dynamic balance” resulting in some vibration in belt wheel center; 4) Suitable for screening of middle and fine materials.

　　Applications:

　　The self-fixed center screen, widely used for materials classification in various industries such as mine, coal, metallurgy, construction materials, refractory materials, light industry, medicine and foods etc., is ideal equipment in crushing & screening system. As it operates with circular traces, it has characteristics of simple structure, durability, good performance, easy for maintenance and efficient screening.

　　Its advantages include also: hanging type and sit type installation; movable frame equipped for small screen; single and multi-layers sieves; transmission installed in left or right; as well as metal woven wire and punching sieves used as screen sieves.
