Principle of Feeder

Feeders operate on various principles depending on the type of feeder and the material being handled. Some common principles include:

• Gravitational Feeding: In gravitational feeders, materials are fed by the force of gravity. The material is stored in a hopper or bin and flows down through an opening or chute onto a conveyor or other receiving device. The rate of feed can be controlled by adjusting the size of the opening or the angle of the chute.


• Vibratory Feeding: Vibratory feeders use mechanical vibrations to move materials. An electric motor or other power source drives a vibrating mechanism that causes the feeder tray or chute to vibrate. The vibrations create a forward motion of the materials, allowing them to be fed at a controlled rate. Vibratory feeders are often used for handling granular or powdered materials.


• Auger Feeding: Auger feeders use a rotating screw or auger to move materials. The auger is housed in a tube or trough and rotates to push the material forward. The rotation speed of the auger can be adjusted to control the feed rate. Auger feeders are commonly used for transporting viscous liquids, powders, or granular materials.


• Conveyor Belt Feeding: Similar to a regular conveyor belt, conveyor belt feeders use a moving belt to transport materials. The belt is driven by a motor and can be adjusted in speed and direction. Conveyor belt feeders are often used for handling solid objects or packaged goods and can be integrated with other conveyor systems for seamless material handling.

Features of Feeder

1. Adjustable Feed Rate: Most feeders have the ability to adjust the feed rate to meet the specific requirements of the application.
