Lock Hopper - an overview | ScienceDirect Topics

Lock hoppers provide a means of both allowing operation of many feeding devices that have only a low-pressure capability, to operate at very much higher pressures, and allowing continuous conveying from a single blow-tank feeder. The lock hopper is located between the supply hopper, which will generally be at atmospheric pressure to allow continuous loading of material, and the material ...
