Bridge Breaker® & Flow Promotion Device Controller

The Bridge Breaker® Controller (BBC) is a self-contained unit capable of operating a variety of Flow Aid devices (FADs) for the purpose of insuring material flow thru hoppers, silos chutes or vessel. It can control various devices such as Thayer’s Bridge Breaker®, vibrators, Air Cannons, Air Pads, etc. or combinations thereof.

Product Description

BB controller pagesBRIDGE BREAKER® & FLOW PROMOTION DEVICE CONTROLLER

An advantage of Thayer’s BBC is the ability to finely control the ON/OFF time of the FADs. In particular, the BBC has the ability to adjust the time between activating the FADs proportional to a signal from an external device such as a feeder. This way, the FADs are activated only as often as is necessary. Using a FAD too often can cause problems with the material as well as being a tremendous waste of energy. The BBC can also tie (link) channels together, which allows cascading of the FADs to effectively and efficiently keep the material moving.

Each channel is capable of controlling up to two solenoid operated air valves, each of which can operate one or two Bridge Breaker® screens or other Flow Aid Devices. It is important to understand that a flow aid device doesn’t move material, gravity does. The function of a flow aid device, such as a Bridge Breaker flow aid, is to break down the formation of “arches” that support the material bearing down from above. When the arches are broken, the material must have a place to go, otherwise serious over-compaction can result.
