Pendulum feeder is used for sending the granular materials from the storage chute to all types of material receiving devices through funnel in ore beneficiation, coal, chemistry and other departments. Pendulum feeder is not suitable for feeding dry powder materials or the materials with big granularity, otherwise there will be powder dust pollution and the discharging mouth may be blocked. 

Pendulum feeder can evenly and continuously feed the bulk and granular materials from storage bin to the material receiving device at regular time in the production process. In the stone production line, it can continuously and evenly feed materials to the crusher equipment and coarsely screen the materials. Pendulum feeder is widely used in the crushing and screening combination plant in such industries as metallurgy, coal, ore beneficiation, building material, chemistry and abrasive materials industry.

Working Principle

When the electro motor is started, its power is transmitted to the reducer for reducing the speed through the V-shaped belt. The reduced power is transmitted to the eccentric gear with adjustable eccentric distance (the adjustment of the feeding amount needs to adjust the position of the eccentric gear) and the eccentric gear drives the baseboard of the pendulum to move back and forth like an arc through the connecting rod, so that the feeding mouth will open and close repeatedly. The rocks in the ore storage bin above the feeder machine are fed in from the feeding mouth and then evenly discharged from the machine to make sure the ball mill is evenly fed in with materials.
