DMA series of electro-magnetic vibrating feeders can be widely used in metal-working, coal, electricity, machinery, chemical, building material, light industry, cereals, and many other industries to evenly and continuously feed lump, grain, or powder materials from hopper to receiver at fixed rate.
DMAseries of electro-magnetic vibrating feeders have following characteristics:
1. SCR half-wave rectifying circuit is used, and feed volume of machine may be infinitely adjusted within rated capacity.
2. Auto amplitude-stabilizing control system may be offered according to customers’ requirements. Maximal amplitude fluctuation of feeder is within ±3%. If microcomputer control-box is equipped with machine, material feeding can be automatically controlled with “local” and “remote” functions.
3. Whole machine is simple-structured, light, easy for maintenance, and no need to lubricate.
4. Due to similar resonance principle, energy-consumption of machine is very low. In addition, material in trough makes parabolic movement, and wear to trough is very small.
