Even in today’s age of highly automated process industries, one of the biggest problems encountered is the removal of bulk solids from storage bins or hoppers. The inability to achieve a consistent flow of material from a storage bin at desired discharge rates is most likely due to the bridging of the material within the bin.
Bridging, or arch effect, is usually due to any one or a combination of three prime factors – the physical characteristics of a given material, bin size and/or configuration, and environmental effects.
The Thayer Bridge Breaker™ is designed to overcome these factors and assure reliable discharging of materials which have a tendency to bridge, cake, flush or otherwise obstruct free and consistent flow.
Thayer’s Bridge Breaker™ is designed to move hard to handle material which have a tendency to bridge, rate-hole or otherwise obstruct free flow through a silo, bin, hopper or chute. The Bridge Breaker™ is constructed from either expanded metal or bars screens, designed to individual bin configurations. The screens are internally mounted, parallel to the bin walls. An externally, mounted vibrator, transmits a rapid vibrating action to the screens by means of bolts that pass through the bin wall. The bolts pass through vibration mounts permitting the Bridge Breaker™ screen to vibrate freely with respect to the bin and other stationary equipment.
The screen is placed within the bin at critical points where bridging or arching might occur. When this happens, operation of the Bridge Breaker™ screen undercuts the bridge of material to fall to the discharge point of the bin. By continuously operating the Bridge Breaker during discharge operation, bridges are prevented from forming thereby maintain a continuous material flow.
Inasmuch as the motion of the vibrating screen is always parallel with the sides of the bin, the vibration does not tend to compact the material as is often the case with bin wall mounted vibrators. The screen sections are adaptable to either flat or conical surfaces and are specifically designed for your application.
Bridge Breakers are suitable for operation with hard to handle material such as titanium dioxide, clays, pigments and a multitude of varying handling characteristics. Bridge Breaker™ screen assemblies can be provided for areas up to four square feet depending on the type of material and bin configuration. As many Bridge Breakers as desired can be mounted within a bin. However, in most instances only a few Bridge Breakers will do the job when mounted at the critical points.
