1. Product Overview
Disc feeder is a continuous quantitative feeding equipment widely used in mining and building material production lines. It feeds materials by centrifugal rotation of the disc with uniform discharge and easy flow adjustment. Usually installed under silos and hoppers, it feeds crushers and conveyors evenly to ensure stable operation of the whole production line.
2. Detailed Description
This equipment utilizes a horizontally revolving disc powered by a vertically configured, heavy-duty gear drive assembly. Material drops from the upper hopper onto the center of the rotating disc, forming a natural material stack. As the disc revolves, an adjustable scraper blade shears the material off the edge of the disc at a controlled rate, routing it directly to the next process. The entirely enclosed drive mechanism features premium oil-bath lubrication to protect internal gears from abrasive dust and fine contaminants. Additionally, operators can easily recalibrate the feed rate on-the-fly by either adjusting the height of the discharge gate, varying the scraper blade angle, or integrating a variable frequency drive to alter rotation speeds.
3. Why Choose Us
-
Uniform and stable feeding with adjustable flow rate: Accurately control feeding volume by adjusting scraper, silo height and disc speed, avoiding unstable intermittent feeding.
-
Suitable for dry/wet powder & granular materials, anti-blocking performance: Rotary disc pushes materials smoothly, handles sticky ore powder, aggregate and coal powder without arching or silo blockage.
-
Sturdy and wear-resistant structure with long service life: Thickened wear-resistant liner on disc surface, heavy-duty reducer motor, suitable for continuous heavy feeding of ore and building materials.
-
Various adjustment modes, simple and convenient operation: Manual feeding adjustment and frequency conversion speed regulation are available, can remotely link crushing lines to match feeding demand of crushers automatically.
-
Good dust sealing performance, meet environmental protection standards: Fully enclosed feeding structure reduces dust leakage, works well with dust collectors to satisfy factory environmental standards.
-
Wide matching scenarios for all crushing & screening lines: Quantitative feeding for mines, aggregate plants, cement plants and power plants, matched with jaw crushers, cone crushers and screening machines.
