Vibra-Drum® Sand and Casting Processors
Proven in hundreds of applications worldwide, VIBRA-DRUM® sand and casting processors have revolutionized high volume mold/sand handling for foundry applications. This versatile two-mass system removes sand and tramp metal without damaging castings, reduces sand lumps to original grain size, and equalizes shakeout sand temperature — all in one continuous, energy-efficient operation.
Two-mass vibrating drums deliver high capacity to 400 TPH, plus superior material motion for efficient sand and casting processing. Natural frequency vibration produces a beneficial drum-like rotary motion 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 rotating drum — but with no air handling, sealing, or interface problems and no casting damage. Our non-rotating drum design simplifies the installation of feed and discharge systems and facilitates in-process inspection.
Features:
Upset Conditions: The two-mass sub-resonant tuned system of the VIBRA-DRUM is designed to compensate for variations in load size and weight.
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 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 rotary motion that quickly reduces sand lumps without casting damage. High frequency agitation efficiently reduces sand to original grain size. The tumbling action of the VIBRA-DRUM scrubs the casting surfaces without castings sustaining 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.
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.
