Working Principle 

Feed: When there is no discharge instruction, the cylinder is in its initial position. Under this situation, the feed bin's upper mouth is opened and the lower is closed. Then the fluidized Al2O3 powder from inlet flow into bin to finish feed.

Discharge: When get discharge instruction from cell control box, cylinder drives the cover plates of spindle and bin. Under this situation, the feed bin's upper mouth is closed and the lower is opened. And the Al203 powder stop to flow into the bin and flow out from outlet to finish discharge. In general, it takes 3 seconds. After the cylinder drives the cover plates back to feed status and finish a discharge cycle.


1.Good seal effect. By spring preloading device, the seal degree can reach 100%.

2. The seal air in the cylinder when feed can be timely discharged to ensure accurate constant volume, repeat accuracy and error is not more than plus or minus 1%.

3.By spring automatically compensate seal after wear, durable and continuous discharge can reach more than 700000 times.

4. Oscillating cylinder moving parts completely isolates AL203 in feed bin, which help reduce the wear and maintenance cost.

5.Using double seal respectively adjusted structure to make the upper and lower of feeder and feed bin seal more solid and durable.

6.Easy ti install and maintain.

As a professional manufacturer for aluminum smelters, we have rich experience and good reputation at home and aboard. Our products have been exported to Malaysia, Turkey, Iceland, Sweden, ect.
