The device structure in sand and gravel production line for continuous crusher crusher evenly feeding avoid clogging by the discharge port. Feeder is the use of a vibrator in the eccentric rotation of the centrifugal force, so that the screen hand, vibrators and other moving parts as mandatory continuous circle or an approximate circle movement. Materials in the car with the screen tilted screen surface for continuous throwing motion, and continuous uniform within the material sent by the spout. Maintenance requirements 1, feeder during operation should always check the surface temperature of the motor current and the amplitude of the vibration of the motor, even before the requirements of amplitude, not about swing shake supply feeder, vibrating motor current stability, such as unusual circumstances vibration feeder manufacturer, should immediately stop processing. 2, the vibration motor bearing lubrication is the whole key feeder working properly, in the course of the second-rate should be regularly filling molybdenum bearing # 2 grease, filling a feeder every two months, the hot season Fill once a month, once every six months to overhaul the motor, replace the bearing. Feeder manufacturers, Hunan feeder, Taihang mine by mine Weihui Taihang Machinery Factory. Weihui Taihang Mine Machinery Factory (www.thksjxc.com) strong, credible, Xinxiang in Henan and other transportation equipment industry has accumulated a large number of loyal customers.
