A vibrating feeder is a critical piece of equipment in coal handling plants, responsible for uniformly feeding bulk materials like coal into processing or conveying systems. In a coal handling plant, vibrating feeders are mainly used for the following functions.
Application of vibrating feeder in coal handling plant
1. Feeding Coal from Storage
Vibrating feeders are placed under coal hoppers, bunkers, or silos to extract coal stored in large quantities. These feeders ensure a smooth, controlled, and continuous flow of coal to the conveyors or crushers for further processing.
2. Pre-Screening Coal
Some vibrating feeders come with screening capabilities, allowing them to separate large-sized coal particles from smaller ones or to remove unwanted materials like rocks and debris before the coal reaches the crushers or conveyors.
3. Preventing Blockages
Vibrating feeders help prevent blockages or bridging in the hoppers or bunkers by ensuring an even distribution of coal across the feeder’s surface, avoiding irregular material flow. This steady flow reduces the chance of equipment overloading and improves the efficiency of downstream processes.
4. Controlling Material Flow Rate
In coal handling plants, it’s crucial to control the rate of coal feeding to match the processing system’s capacity. Vibrating feeders are often equipped with adjustable speed settings, allowing operators to regulate the flow of coal according to the plant’s requirements.
5. Maintaining a Uniform Coal Stream
The vibrating action of the feeder ensures that coal particles are uniformly distributed across the width of the conveyor belt or crusher inlet. This uniform flow minimizes the risk of material segregation and improves the efficiency of coal handling.
