Introduction This machine is composed of screen box, vibrating motor, damping system and bottom rack. Screen box is consisted of deck base, screen plate, scale-board etc. It adopts high function and long life YZO series vibrating motor or exciter as exciting source to adjust the size of exciter force, in order to change swing of sifter machine. The damping system is made up of rubber spring, hoop and supporting base. The bottom rack is consisted of hopper and chasis rack, installation method of exciter source is divided into upper vibrating or under vibrating, installation method of vibration reducer is divided into base or suspention. We also can design and manufacture according to users requirement. Working Principle Screen self-synchronous reversed rotation depends on two sets of same vibrating motors or general motors along with exciter, and makes the whole screen machine supported on vibration reducer moves on a linear trajectory quickly go ahead and loose to complete screening operation after materials fall into screen from inlet. XBZS series cantilever bar vibrating sifter is driven to rotate synchronously in opposite directions by two same vibration motors or electric motors with exciters, which makes the screen body move on periodical and to-and-fro linear trajectory to achieve screening classification. Features The deck of bar screen should be inclined installed, the angle is during 20 degree to 35 degree. When comparing with other same type has following difference: 1.small volume , big inclined angle and screening capacity. 2.light weight, easy installation. 3.low price and energy consume. 4.simple construction and beautiful shape. 5.the efficiency of the screen mesh is more over 20% than the general screen mesh. 6.self-cleaning. 7.specially using for secondary screening under the high furnace groove. 8. Large inclination installation of screen surface(20°-35°), small volume, large capacity. 9. Light weight for easy installation;low power consumption for energy-saving. 10.Low cost and little spare parts;simple structure and attractive appearance. 11.Self-cleaning function, specially for secondary screening below blast furnace bin. Application XBZS series bar screen is a new type screen equipment , Suitable for the classification of big materials, medium and small granular materials. it is widely used in mining, coal, energy power, metallurgy, building materials, fire-resistant, etc.
