Built on our legendary rugged chassis and components, the Voyager smart sorter offers an unparalleled number of adjustment points and power automation to simplify the purification setup with intelligent processing. Programmable Logic Circuitry with a pre-loaded menu of up to 20 separation “recipes” means faster and simpler changeover between different products, our density separation equipment is for optimal separations from even the most minimally-trained operator no matter what your density separation, size separation or contaminant removal needs.
Key features:
Processing up to 18,000 pounds per hour
Variable frequency drive for precise speed control
Intuitive manual controls with adjustable dual-axis tilt
Multi-fan system with independent fan dampening control
Gauges for side tilt, end raise, feed flow, air flow pressure, and eccentric speed
All adjustments safely made while in operation
How do Oliver Manufacturing gravity separators work?
Oliver Manufacturing’s gravity separator machines, commonly called Oliver gravity tables, divide heavier particles of material from lighter particles differing in their specific densities. On gravity separators, lighter particles are moved upward through the fluidized bed, and heavier particles sink downward. This air essentially makes the particles weigh themselves. The deck itself is tilted uphill and quickly shifting in a perpendicular eccentric motion. This allows the lighter particles to flow over the top of the heavier particles to the bottom of the deck while heavier particles are driven up and over the top. This process allows our gravity separators to separate both light and heavy contaminants from a product simultaneously.
The air, eccentric motion, deck tilt, end raise, and feed rate on an Oliver gravity separator are easily modified and can retain adjustment settings for multiple products. Adjustments to the air, motion, and tilt affect the quality of the separation, while the end raises, and feed rate affects capacity.
In the gravity separator stratification process, A shows mixed particles resting on the deck, B shows upward airflow fluidizing the material so lighter particles rise and heavier particles settle, and C shows air, deck tilt, and eccentric motion working together to separate particles by density.
