<p>PRONGED VIBRATOR A vibrator with attached prongs which achieves the breakup of compacted materials in structures similar to silos, grain elevators and railroad cars is set forth. Attached to the pronged vibrator is a cable which allows the vibrator to be lowered into the structure where breakup is to be accomplished. The vibrator is housed within a shell of dimensions applicable to the particular use. Secured to the vibrator shell are a multiple of prongs. The vibrator when in operation not only causes the sphere to vibrate, but also the attached prongs. The vibrator is capable of imparting varying frequencies to the compacted materials and may be adjusted to reach the natural frequency of the compacted material. Thus, where the vibrator comes into contact with the compacted material, breakup is achieved both by the physical action of the prongs and also achieving the natural frequency of the material which in and of itself causes breakup.
