Vacuum feeder is mainly used for conveying powder and granular materials, widely used in food industry, pharmaceutical industry, metallurgy, mining, chemical industry.
1, Use the compressed air when it passing through the vacuum generator and produce high vacuum to achieve the conveying of materials, no need for mechanical vacuum pump. It has many characteristics such as simple structure, small volume, free maintenance, low noise, convenient control, eliminate material static electricity and so on.
2, The high vacuum produced by the vacuum generator, making the material be transported to eliminate the stratification phenomenon, to ensure the uniformity of the composition of mixed materials. It is the feeding device of Various mechanical equipment, such as tablet press, capsule filling machine, dry granulation machine, packaging machine, crusher, vibrating screen.
3, When the compressed air is supplied to the vacuum generator, the vacuum generator produces negative pressure to form a vacuum airflow, and the material is sucked into the suction nozzle to form a material airflow, which reaches the bin of the feeding machine through the suction tube.
4, The filter separates the material from the air thoroughly. When the material is filled with the bin, the controller will automatically cut off the air source, the vacuum generator stops working, and the bin door automatically opens, and the material falls into the hopper of the equipment. At the same time, compressed air automatically cleans the filter through a pulsed blowback valve. When the time is up or the material level sensor sends out the feeding signal, the vacuum conveyor will be automatically started.
