Dust collectors have hoppers under the collection chambers to channel the dust out of the system for use or disposal. The hoppers are not designed to be used to collect and store the material, but rather as a place for the material to temporarily collect before passing through the airlock and out of the system.
Dust Build-Up in Hopper
Depending on the material being collected and the characteristics of it, dust may temporarily build up in the hopper until it can pass through the airlock. Applications that have periodic high loading or applications that have materials with irregular shapes, are sticky, or hygroscopic could all build up in the hopper and form a bridge or rat hole by the dust discharge opening. When this happens, one of the most common solutions is to install a vibrator on the hopper. The vibrator works by hitting the side of the walls which can cause the material to break up and fall through the dust discharge flange and leave the system.
The Purpose of Vibrator on Hopper
Vibrators can be driven pneumatically or electronically. They also can be used to continuously agitate the hopper preventing any bridging from developing, or they can be periodically turned on to break up any bridging that has developed. When you are installing a vibrator, it is important that you let the manufacturer know how you are planning on using the vibrator so they can recommend the correct vibrator for your application.
