Vibrating feeders, AVV series
The AVV series vibrating feeders are used for continuous regulated secondary feeding of any machine and are also used for processing materials that are very dirty or placed under buffer stockpiles. They essentially consist of a fixed frame and a movable carriage connected to the fixed frame by means of four connecting rods equipped with anti-vibration rubber buffers. The part of the carriage that is in contact with the material is lined with bolted armours. The alternating movement of the carriage is generated by the movement of a rod driven by an eccentric shaft which causes the material to flow continuously.
The capacity can be regulated by adjusting the exhaust valve or the variable speed motor that is mounted onto the machine or, on the model without a variable speed motor, by equipping the electric command and control board with an electronic frequency converter, allowing the machine to work at full load at all times.
