Definitions of Vibrating Feeder
In the production process, the vibratory feeder can uniformly, timely and continuously feed bulk and granular materials from the storage bin to the receiving device. In sand and gravel production lines, the vibrating feeder can provide continuous and uniform feeding to crushing machinery and carry out rough screening of targeted materials. This vibratory feeder is widely used in combined crushing and screening equipment across industries including metallurgy, coal mining, mineral processing, building materials, chemical industry and abrasives.
Equipment Application
This vibrating feeder is specially designed for the uniform feeding of large-sized materials ahead of primary/secondary crushers in crushing and screening operations. The vibratory feeder adopts a dual eccentric shaft exciter structure, which guarantees the equipment can withstand the heavy impact of falling large materials and boasts a high feeding capacity. In the complete production flow, the vibrating feeder can transfer bulk and granular materials from storage bins to receiving devices uniformly, regularly and continuously, thus preventing unexpected downtime of receiving equipment caused by uneven feeding and effectively extending the overall service life of the equipment.
Vibratory feeders are available in two structural types: steel plate structure and grizzly bar structure. Steel plate structured vibrating feeders are mostly applied in sand and gravel production lines to deliver all materials evenly into crushing equipment; grizzly bar structured vibratory feeders can conduct rough screening of materials, making the entire system configuration more economical and rational, and such feeders have become an indispensable piece of equipment in crushing and screening plants worldwide.
Feed Size: ≤1200 mm
Capacity: 60–800 t/h
Applicable Materials: Suitable for combined crushing and screening equipment in industries including metallurgy, coal mining, mineral processing, building materials, chemical engineering and abrasives.
Equipment Structure
In sand and gravel production lines, the vibratory feeder supplies continuous and uniform feeding to crushers, thoroughly avoiding blockage at the crusher feed opening. The vibrating feeder operates by utilizing the centrifugal force generated by the rotation of eccentric blocks inside the vibrator, which forces movable components including the screen box and vibrator to conduct forced continuous circular or approximate circular motion. Materials then perform continuous throwing movements along the inclined screen surface with the screen box, and are sent continuously and evenly into the crusher feed opening steadily.
Equipment Advantages
● The vibratory feeder features stable vibration and highly reliable operation.
● Equipped with adjustable grizzly bar gaps for flexible material handling.
● Configured with sufficient durable wear-resistant components.
● Adopts a specialized grizzly bar design to effectively prevent material blockage.
●Separates fine materials automatically to protect wear parts from abrasion and boost overall production output.
● Variable-frequency drive motor is available as an optional accessory to adjust working frequency and output, enabling easy control of feeding rate without frequent motor startup.
● High starting frequency performance:
(1) Taking the entire production line into account, the vibrating feeder relieves the working load on jaw crushers and impact crushers significantly.
(2) Effectively avoids frequent startup of high-power processing equipment.
