Proven in hundreds of applications worldwide, VIBRA-DRUM® Sand & Casting Conditioners have revolutionized high volume mold/sand handling for foundry applications. This versatile Two-Mass system gently tumbles castings and provides accelerated casting cooling through equalizing of sand/casting temperatures and evaporation of moisture. This tumbling action reduces sand lumps to original grain size and blends sand to equalize shakeout sand temperature — all in one continuous, energy-efficient operation.

The gentle tumbling action of the VIBRA-DRUM® keeps the castings in a bed of sand, never dropping or creating impact during the shakeout process. This action provides the gentlest shakeout in the industry, allowing the automated shakeout of fragile castings.

The Two-Mass VIBRA-DRUM® delivers continuous shakeout operation, plus superior material motion for efficient sand and casting processing. Natural frequency vibration produces a beneficial drum-like material rotation that quickly reduces sand lumps without casting damage. High frequency agitation efficiently reduces sand to original grain size. Put it all together and you have a simple, easy-to-maintain, non-rotating design with all the environmental benefits of a totally enclosed drum — but with no air handling, sealing, or interface problems and no casting damage.

Features:

  • The Two-Mass sub-resonant tuned system of the VIBRA-DRUM® is designed to compensate for variations in load size and weight.
  • Totally enclosed structure reduces dust collection requirements.
  • Castings come out cleaner and cooler with reduced scrap when compared to rotary or brute force vibratory drums.
  • The VIBRA-DRUM®  brings controlled metallurgical cooling to castings.
  • Springs: GK vibratory springs are designed for 24/7 continuous duty, and require little to no maintenance over the life of the machine. GK heavy-duty springs do not break or wear out under normal operation.
  • Parts: The natural frequency drums have few moving parts. Maintenance for sand casting equipment is contained to bearing lubrication and monitoring of motor and drive components.
  • Drive Force: Natural frequency vibration of the VIBRA-DRUM® produces a beneficial drum-like material rotation that quickly reduces sand lumps without casting damage. The tumbling action of the VIBRA-DRUM® scrubs the casting surfaces without sustaining casting damage.
  • Non-rotation design is easier to feed, easier to unload, and easier to maintain.
  • Heavy-duty liners are made of abrasion resistant wear plate to last.
