The Adjustment of the Feeding Amount of Pendulum Feeder

The pendulum feeder is the device that sends the granular materials from hopper via the stock chest to the feeding device in the beneficiation, coal, chemical and other sectors. The pendulum feeder is not suitable for the delivery of dry powdery materials or the materials of too large particle size; otherwise it will cause the dust pollution and the clogging of the discharge port.

Compared with other feeding equipment, the pendulum feeder is equipped with the regulating shutter that is vertically mounted in the box structure. The control of the feeding amount of the material can be realized by adjusting the degree of opening of the regulating shutter and it will also make the material loose in the discharge, achieving the uniform, thin layer and continuous feeding. In addition, the horizontal gate is set, which makes it convenient to conduct the maintenance and overhaul of the machine. The inverter motor is used to control the eccentric crank speed to achieve the precise control of the feeding amount. The pendulum feeder is featured with the advantages of flexible adjustment, precise control, easy maintenance, reasonable structural arrangement and balanced force and other advantages.

To adjust the eccentric distance of the eccentric pin on the eccentric wheel can change the length of the stroke of the swing base plate, which makes it possible to adjust the feeding amount to the large range, to adjust the level of feed port shutter and to change the size of the discharge port, making precise adjustment of the feeding capacity.
