Bridge Breaker® Controller (BBC)

Thayer’s 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 flows freely thru a hopper, bin or silo even at variable flow rates. It can control various devices such as Thayer’s Bridge Breaker®, electric or pneumatic vibrators, Air Cannons, Air Pads, or combinations thereof.

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 be synchronized with a measurement of the outgoing material flow rate from a feeder or metering device. This way, the FADs are activated only as often as is necessary. Using a FAD too often can cause problems with the material discharge 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.

A single Bridge Breaker® Controller contains four separate channels and 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.
