Maxi-Cap Gravity Table Separators

Maxi Cap Gravity Separators are the highest capacity grain gravity separators on the market, capable of separating up to 40,000-42,000 lbs. of material an hour depending on the product. Offer quick and straightforward setup, cleanup, and changeover. With this impressive volume, Maxi Cap Gravity Table Separators are ideally suited for larger operations that process tons of dry bulk materials every day.

This can include a variety of grains, seeds, beans, nuts, stones, precious metals, plastics, and other small particles that are similar in size and weight. A grain gravity separator will extract heavier, denser particles, impurities, and contaminants from product that is the same size and shape but lighter. This process helps to purify the product and increases its value. Maxi Cap Gravity Separators are incredibly efficient and accurate, able to separate like-sized particles with a difference of as little as 0.5% in density.

Our Maxi Cap Gravity Table Separators include hydraulic adjustments and electronic controls that can be used to enhance quality and make the machine better suited for your operations. The machine also features quality construction, ensuring decades of reliable and predictable operation.

How it works

Our Maxi Cap Gravity Separators use a combination of air, eccentric motion,  deck tilt, end raise, and feed rate to separate a variety of materials by particle density. Once the Maxi-Cap Gravity is turned on, all adjustment setting should be set for the specific product to allow a proper separation. On the Maxi Cap Gravity Separator, (models 3600 & 4800), 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.
