Destoner
Efficient Separation of Stones and Heavy Impurities from Grains
The Destoner is a vital grain cleaning machine designed to remove stones, heavy dirt, and other dense impurities from grains, pulses, and seeds by exploiting differences in specific gravity and particle size. Using a combination of vibration, air flow, and inclination, the destoner ensures high purity of the final product, protecting downstream processing equipment and enhancing product quality.

Key Features
Gravity Separation Principle
Utilizes difference in density to separate stones from grains.
Inclined & Vibrating Deck
Oscillates material for efficient stratification and separation.
Adjustable Air Flow
Precisely controlled suction removes lighter particles while heavy stones settle.
Multiple Deck Options
Single or double deck for higher capacity or finer separation.
Robust Construction
Fabricated with Mild Steel or Stainless Steel (optional) for durability and hygiene.
Easy Maintenance
Quick access to decks and blowers for cleaning and servicing.
Low Noise & Energy Efficient
Designed for smooth operation and reduced power consumption.
Compact Footprint
Can be integrated into existing grain cleaning lines with minimal space.
