The ZF shaker is a coal slurry dewatering sieve operations equipment for coal preparation, mineral, chemical, power, sugar, salt and other departments in the fine-grained dry and wet sieving slime recovery, pressure filtration separated from crude filter every crude dehydration, sculping desliming, reasonable structure, durable, low noise, easy maintenance. Selection and orders should be marked with the mesh structure (weaving, punching, crack), mesh size, processing capacity, the name of the material, feed size, sieve dehydration using a dual-motor synchronization technology, general-purpose eccentric adjustable amplitude vibrator. Mainly composed of screen box, shaker, support system and the motor. Through the coupling of tape were driving two unconnected vibrator synchronous reverse operation, the centrifugal force generated by the two groups of eccentric mass is superimposed along the vibration direction of the force, reverse centrifugal offset to form a single along the direction of vibration-induced vibration , so that the screen box artificial reciprocating linear motion.
