Gravity separators
Precision density separation for cleaner, more consistent product
Maxi-Cap gravity separator
Models: 3600, 4800, 3600P, 4800P
The “big brother” of our Hi-Cap series separator delivers unexcelled cost efficiency on high volume installations where density separation, contaminant removal, and size separation are needed. The Maxi-Cap high volume material separation machine removes heavier stone, glass, metal and sands as well as lighter lumber or agriculture products or plastics. Precise hydraulics and Opti-Drive automation make adjustment during operation a snap. Aspirating feeder removes the lightest contaminants as product is being introduced.
Key features:
Processing up to 30,000 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.
