Depending on your unique application, different equipment solutions may fit your operations, such as sand preparation, pouring, molding, and casting better than others. In the past separate units would be used for sand conditioning, casting, cleaning, and cooling. However, GK offers a solution that will save space while providing all three functions in one unit. Proven in hundreds of applications worldwide, General Kinematics’ 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 free 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 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. This provides 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.
