Pendulum Feeder

The Introduction of Pendulum Feeder

Pendulum feeder, also known as tilting feeder, is an auxiliary equipment for transportation, which is suitable for short distance, small and heavy material, and its particle size in 35 ~ 100 mm. The pendulum feeder transfers the granular material from the storage tank to various types of receiving devices through the funnel, but it is not suitable to transport the dry powder or too large particle size material, otherwise dust pollution and discharge port blockage will occur. The pendulum feeder is suitable for mineral processing, coal, chemical industry and other departments, most as the feeding equipment of ball mill collection belt conveyor.

The Applications of Pendulum Feeder

The Advantages of Pendulum Feeder

• No rotating parts do not need lubrication, and easy maintenance, low operating costs.
• Using the resonance principle of mechanical vibration, and the double body works in the low critical state of near resonance, so it consumes less electric energy.
• Because it can change, open and close the material flow instantaneously, the feeding quantity has higher precision.
• The pendulum feeder adopts closed structure fuselage, which can effectively prevent dust pollution. And it can realize the centralized control and automatic control of the production process.
• Vibration motor is vibration source, low noise, low power consumption, good regulation performance, and no blanking phenomenon.

The Working Principle of Pendulum Feeder

When the motor is started, its power is transferred to the reducer through the triangle belt to decelerate, and the decelerated power is transferred to the eccentric wheel of eccentricity (the size of the ore supply shall adjust the position of the eccentric wheel), and then driven by the eccentric wheel through the connecting rod to swing the bottom plate for reciprocating arc swing, so as to open and close the feeding mouth repeatedly. The ore in the square ore bin of the feeder is discharged through the feed port at a uniform speed again and again to ensure the uniform feed production of the ball mill. If you want to adjust the amount of ore fed by the feeder, the length of swing stroke can be changed to adjust the amount of feed in a larger range. Adjusting the height of the outlet gate can change the size of the outlet, so as to accurately adjust the feeding amount.

The Instruction Manual of Pendulum Feeder

• If the pendulum feeder is used for batching and quantitative feeding, it should be installed horizontally to ensure even and stable feeding and prevent material self-flow. If it is used for continuous feeding of general materials, it can be installed with a downward inclination of 10°. For sticky material and material with large moisture content can be inclined down 15° installation.
• After installation, the feeder shall leave a 20mm swimming gap, and shall be horizontally oriented. The suspension device shall be flexibly connected.
• Before test, all bolts should be strengthened once, especially the anchor bolts of vibration motor, which should be tightened once again after continuous operation of 3-5 hours.
• The two vibrating motors must be rotated during the test run
• During feeding, the stability of amplitude, current and noise should be checked frequently.
• Motor bearings should be lubricated every 2 months, and lubricated every month in high temperature season.
