Key takeaway: A vibrating ore drawing machine (vibrating ore feeder) uses vibrating motors (or electromagnetic exciters) as its power source. Eccentric blocks mounted on the motor shaft rotate to generate centrifugal exciting force, which drives the trough in periodic linear reciprocating vibration, so the ore is thrown up and leaps forward along parabolic trajectories — achieving continuous, controllable ore drawing and feeding. It is widely used for underground orepass drawing, bin/silo discharge, and mill/crusher feeding.
Working principle: Vibrating motors carry adjustable eccentric blocks on both ends of the shaft; the centrifugal force of their high-speed rotation is the exciting force. This drives the deck (trough) into periodic linear reciprocating vibration along the inclined direction. When the vertical vibration acceleration exceeds gravitational acceleration, the material is thrown off the trough bottom and leaps forward along a parabolic trajectory; throw and landing happen almost instantly and repeat continuously, achieving continuous, controllable ore drawing and conveying.
Key advantages
- Continuous, uniform drawing with stepless capacity adjustment (eccentric-block angle or VFD);
- Strong resistance to arching/blockage — cuts secondary breaking and manual poking, improving both productivity and safety;
- Simple construction, low energy consumption, easy maintenance, and easy integration into automated control systems;
- Flexible installation at orepasses, bins, stopes, and crusher inlets.
