Heavy-Duty Disc Feeder

1. Product Overview

The Heavy-Duty Disc Feeder is a premier volumetric feeding solution engineered for the uniform and controlled extraction of granular and powdery materials. Widely utilized in mining, metallurgy, cement, and chemical processing lines, this equipment sits directly under storage bins to regulate the feed to conveyors, mills, or crushers. It handles challenging, sticky, or moist materials—such as iron ore concentrates, coal dust, limestone, and clay—ensuring an uninterrupted production flow where traditional vibratory or belt feeders often fail.

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.
