Brief description
Pneumatic vacuum feeder uses compressed air to generate high vacuum through a vacuum generator to transport materials, without the need for mechanical vacuum pumps. It has the advantages of simple structure, small volume, maintenance free, low noise, easy control, elimination of material static electricity, and compliance with GMP requirements. The high vacuum generated by the vacuum generator eliminates the phenomenon of layering in the conveyed material, ensuring the uniformity of the mixed material composition. It is a mechanical automatic feeding equipment such as tablet press, capsule filling machine, dry granulation machine, packaging machine, crusher, vibrating screen, etc.
Main features
When compressed air is supplied to the vacuum generator, the vacuum generator generates negative pressure to form a vacuum airflow. The material is sucked into the suction nozzle to form a material airflow, which passes through the suction tube and reaches the feeding bin of the feeder. The filter completely separates the material from the air. When the material is filled in the silo, the controller will automatically cut off the air source, the vacuum generator will stop working, and the silo door will automatically open, allowing the material to fall into the hopper of the equipment. At the same time, compressed air automatically cleans the filter through a pulse blowback valve. When the time is up or the material level sensor sends out a feeding signal, the feeding machine will automatically start.
The conveying capacity is closely related to the conveying distance and material characteristics
