Bridge Breaker® Material Flow Aids

Bridge Breaker® Material Flow Aids

Bridge Breaker®

Design covered by U.S. and International Patents

Operation
An expanded metal screen is mounted inside of and parallel to the hopper wall. The shaker supported frame is rigidly mounted to the screen through the use of two bolt and spacer assemblies. The bolts pass through elastomer sealing mounts which permit the screen to be actuated externally by the shaker assembly. A support bar welded to the hopper supports the shaker reaction spring and shaker assembly. The shaker which is air operated imparts a thrusting action to the screen with an amplitude (typically ±1/8”) which is effective in shearing or under-cutting material producing gravity flow. Quiet operation is assured.

Typical Installation

Bridge Breaker single material flow aids or multiple material flow aids can be used in common bins and chutes to prevent formation of rat holes or material bridging. Larger installation commonly require more than one flow aid, staggered in mounting height around the circumference of the outlet. Activation can be sequenced to create maximum, cascading effect.

THAYER Bridge Breaker® flow aids are custom manufactured to meet a particular bin configuration, type of material, or unique installation application. Bridge Breaker Screens come in a number of different configurations.
