It is widely used in coal classification, desliming, dehydration, and demediation. It can also be used for screening processing in large-volume material mining operations in mines.
Screening, grading and dehydration of coal, coal stone, coal slime and other minerals.
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.
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.
Dewatering screen adopt dual-electrode self-synchronization technology, universal eccentric block, adjustable amplitude vibrator. The machine is combined mainly by the screen box, exciter, support system and motor. The two mutually independent vibrators are respectively driven by the tape coupling to do synchronous reverse operation. The centrifugal force generated by two eccentric masses is superposed along the vibration direction and reversely counteracted, thereby forming a single vibration force along the vibration direction, making the screen box reciprocating linear motion.
Dewatering screen, also known as high-frequency dewatering screen, changing the water surface tension of pulp through the exciting force, pulp water through the screen to become the undersize material, and fine material is blocked by the screen to form the filter layer by the vibration of the forward movement of discharge. Dewatering screen is mainly used for detailings dewatering in the mineral processing industry, coal slurry dehydration of coal preparation plant, washed quartz sand dewatering and ceramic slurry dehydration, and wet and dry classification, dehydration, removal and mud removal of medium and fine granular materials in industrial sectors such as electric power, sugar making and salt making.
