Detailed Description
The Vibra Bucket assists the otherwise tedious screening of fine-mesh sands. It mounts a 30W industrial vibrator inside a heavy-duty 5-gal steel pail with a reinforcing bottom board and base plate to keep the pail flat and ensure vibration up to the screens. A special short, flat-rim 3.5-gal plastic bucket fits above the motor to hold the screen and catch material; the flat rim transfers vibration efficiently from the steel pail. Rubber tape sections inside the rim make a snug fit while leaving small air gaps, so there’s no vacuum seal—your receiver lifts out easily for pouring.
In testing with an 8 lb (≈½ gal) 3:1 mix of −12M/+12M placer sand, the Vibra Bucket delivered ~97% in 1 minute and ~99% in 2 minutes at full vibration. After startup, turning the speed controller down to MEDIUM often screens faster because the sand rides the mesh and more particles find the holes. Full force is useful at the beginning for heavier loads, but shallower batches are recommended; stirring the sand in the screen helps when too much material is added. When any material is added, the noise is dampened.
A field demo re-screened a gallon of waste magnetite to −12M in about 15 seconds, and the added weight reduced noise. The vibration motor is 115–120V AC, and you can run it in the field from a small 12V DC battery using the optional 150W inverter. To prevent the unit from “walking,” tie a cord from the handle to a solid support.
CAUTION: High vibration hazard—do not hold with hands or feet during operation. Secure the unit before running. Screens sold separately elsewhere.
