Working Principle
The entire assembly is vibrated horizontally by the natural frequency drive mechanism. The wedge shape center dome is designed to transmit vibrating forces into the storage pile on the material to reduce the arching and induce the flow in the storage pile. The geometry of the material flow path is similar to the requirements for open pan feeders. The bottom slot opening feeds the material to the belt. Even for lignite coal and other wet coal.

Advantages
EuRoCMA for the global mining companies, thermal power plant, bulk cargo terminal, container transport enterprises specialized in designing, manufacturing and mining activation feeder leading position, the activation of feeder has the following economic, technological advantages:
- The activator feeder combines the flow control characteristics of a vibrating feeder with the material activating action of a vibrating bin bottom. Eliminates bridging even for lignite coal.
- The activator feeder combines the material feeding with baffle gate. When the feeder turns off or power outage suddenly the material in the bin will stop moving. The feeder is as a cut-off gate at this time.
- Large vibrating opening, up to 4m x 4m, permit large hopper discharge openings for greater drawdown volume. Compact, low profile design reduces tunnel depth for a substantial savings in foundation costs.
- Good seal and no leakage of material to create good work circumstance.
- Fully controllable for infinitely variable feed rates to link with automated control system—accurately controls various proportioning and blending operations.
- Symmetrical and centered loading. Unit mounts directly above belt conveyor and evenly distributes material to eliminate belt tracking problems.
- Low headroom design for reduction in installation requirements.
- Two-mass sub-resonance theory leads lower power consumption. Infinite fatigue life design proves super longer service life. Nearly no maintenance.
