BTS rod-type vibrating screen is used for uniform feeding and separation of large materials in front of the crusher. The rod-type vibrating screen is especially suitable for feeding and primary screening before rough crushing of hydropower industry, building stones, ferrous or non-ferrous metals and ores; rod The vibrating vibrating feeder of the vibrating screen uses a vibration motor as the excitation source. It has a simple structure and is easy to maintain. It has large output, long life, and is strong and durable.
Suitable for coal, mining, metallurgy, building materials and other industries.
Raw coal, coke, graphite green balls, petroleum coke, bottom slag, andesite, construction waste, construction stone, metal ore, iron ore, limestone, fluorite, cooled blast furnace slag, etc.
When BTS bar screen work, the exciting force generated by the vibration exciter through the screen box to pass through to the screen surface, because the exciter vibration force generated by the longitudinal force, fForcing the sieve box to drive the sieve surface to make longitudinal before and after displacement. Under certain conditions, the material on the screen surface is thrown forward due to the exciting force, and the material smaller than the screen hole will fall down through the screen to the lower layer. The BTS bar vibrating screen material’s movement on the screen surface is parabolic, and the bar vibrating screen performs the material screening operation due to such repeated movement of the material.
The working principle of ZSG heavy vibrating screen is: after the machine starting, a symmetrical arrangement of two vibration motor or excitation device with same model and specifications for synchronous reverse operation, the vibration force through the vibration body – motor or exciter base passed to the whole vibration body – screen box, makes the screen box drives the vibration screen surface to do cyclical movement, so that the material on the surface of the screen to jump sports with screen box, meanwhile, the material smaller than the screen mesh hole will fall to next layer through, becoming the undersize material, the material bigger than the screen mesh hole will be discharged by outlet after continuous jumping movement, eventually completed screening operation.
YK series circular vibrating screen is composition mainly by the screen box, screen mesh, vibrator and damping spring, etc. Vibrator is installed in the side panels of screen box, which driven by motor through the coupling, produce centrifugal inertia force, making the screen box vibration.
From the point of view of the trajectory of the screen box, which is the screen box, the square swing screen is also called the arc screen. The vibration force generated by the drive device is an inertial force that changes in a certain direction around a fixed axis, and its essence is The reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to the structural characteristics and working principle of the square rocking vibrating screen, the screen surface is generally horizontal or slightly inclined (the inclination angle is 0°~5°). After the screen machine is started, the shaking body of the screen machine, namely the screen box, will reciprocate back and forth under the action of inertial force. The screen box drives the screen surface to periodically shake, so that the material on the screen surface will move with the screen box in a directional jumping motion. During this period, the physical materials smaller than the screen surface aperture fall to the lower layer through the screen holes and become under-the-screen objects. The materials larger than the screen surface aperture are discharged from the discharge port after continuous tumbling and jumping motion, thereby completing the screening work.
