Heavy-Duty Destoner Machine
Remove High-Density Stones That Normal Graders Miss.
Stones that match the exact physical size of your grain cannot be removed by simple sieves, as they pass straight through every screen. Our Heavy-Duty Destoner uses gravity, deck inclination, and air fluidization to separate same-sized stones from grain, protecting your milling rollers from critical teeth breakage.

Core Benefits
Air Fluidization Deck
A uniform air stream blows upward through the grain bed, floating the lighter grain down the deck while heavy stones climb up to the discharge outlet. Physical density differences do the work, eliminating the need for manual picking.
Saves Milling Rollers from Costly Damage
Stones entering your splitters and polishers cause fractures in roller teeth that require expensive replacement and create unplanned downtime. The Destoner stops them before they enter your milling machinery.
Adjustable Air and Slope Controls
Tune the air flow and deck inclination to match the density characteristics of different grains - millet, wheat, heavy pulses, or oilseeds - without tools and without calling a technician.

Frequently Asked Questions
Traditional sieve graders miss these stones because they pass through standard screens. Our destoner uses physical density: since a stone is roughly twice as heavy as grain of the exact same size, upward air fluidization lifts the grain to slide it down the deck while the heavier stone climbs the inclined deck, separating them cleanly.
It works on all food grains, including Toor dal, Chana dal, wheat, soybeans, green gram, and millet.
The standard destoner is rated to process up to 500 to 1000 kg of grain per hour, matching the high throughput required for continuous commercial processing units.
It separates stones before they can enter downstream splitters and polishers, safeguarding against high-impact tooth fracture and sudden mechanical damage to your primary rollers.
The blower fan and deck vibration assemblies run on a 2 HP or 3 HP motor, configurable for single-phase 220V or standard three-phase 415V industrial power grids.
Yes. The operator can manually adjust the deck angle and air velocity in under two minutes, balancing the air flotation bed perfectly for lightweight millets or heavy pulses.
