The vibrating feeder, also known as vibration feeder, is used to transfer the large size materials and granular materials from hopper to receiving device uniformly, periodically and continuously in the production flow. It can feed materials into the crusher continuously and uniformly and can also screen the materials at the same time in the stone production line. The vibrating feeder is widely used to match the crushing and sieving equipments in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc.
The vibrating feeder can make the sieve compartment, vibrators and other moving parts do the circular or similar round move by the centrifugal force produced by the rotation of eccentric block. The vibrating feeder is composed of feeding trough, exciter, spring bearing, transmission equipment, etc. The exciter is composed of two eccentric shaft (main, passive) and gear. The jogged gears create the vibrations while the two eccentric shafts are then forced to rotate by motor, through the triangular belt. Once power is supplied, the two eccentric shafts start rotating to produce leaner huge power which forces the feeder to vibrate. Through the vibration, the materials will slip and sling onto the screen moving forward.
When the vibrating screen is working, under the effect of vibrator, the screen box and screen cloth will move on a circular, oval, or linear motion, which will make the material on the surface of screen disperse and move up and down. Thus, the fine particles can fall through the material layer and then expel from the sieve hole. And the bigger particles will continue to move forward under the effect of vibration. Through the careful observation to the operation process of vibrating screen, the researchers conclude the general steps for the daily maintenance of vibrating screen ---- Learn the operation state of the equipment through observing and listening. That is to say, through observing the indicator on the amplitude sign, and combining the current of the equipment operation, give a synthetic judgment for the working state of the vibrating screen. And the listening means listening to the operation voice of the working equipment to know whether exist the situation of equipment components loosing. Discover in time and dispose in time. Another thing to notice is that the internal dust of the vibrating screen should be cleaned regularly. Vibrating feeder : http://www.best-crushers.com/vibrating-feeder.html
