Feeding Equipment
Disc Feeder
A disc feeder delivers fine ore from a storage bin at a controlled volumetric rate. Its driven rotating disc, feed hopper and adjustable gate set the discharge. Speed variation tailors feed to demand.
Technical parameters
Installed beneath a bin, the disc feeder bridges storage and downstream transport. It commonly supplies conveyor belts, mill inlets or mixing devices. Gentle discharge suits friable ores prone to degradation in vibratory feeders.
The DK series progresses stepwise through increasing disc diameters and corresponding drive power. Larger discs accept coarser feed and yield higher volumetric outputs, while smaller units suit tight layouts and low-tonnage duties. The table is designed so you can match a model by required feed size, flow rate and available headroom.

Standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Use them to shortlist, then confirm the duty by testwork, flowsheet calculation and a written confirmation from the manufacturer.
What decides the selection
Before selecting a disc feeder, confirm the maximum particle size, bulk density and moisture content of the feed. Establish the required feed rate range and the hopper opening geometry. Also note whether the downstream process demands a steady or metered flow, as this influences the mounting configuration and drive control method.
