Industrial Stone Separator & Destoner Machine Manufacturer

MMCTECH manufactures high-performance stone separators, grain destoners, gravity destoners, and seed destoner machines for commercial seed processing plants, grain cleaning facilities, food processing operations, and turnkey agricultural projects. Our destoning systems are designed to remove stones, soil clods, glass fragments, metal particles, and other heavy contaminants that reduce product quality and damage downstream equipment.

Destoning is one of the most critical cleaning stages in modern grain and seed processing. Even small amounts of stones can cause costly damage to mills, dehullers, gravity separators, color sorters, conveyors, elevators, and packaging systems. Installing a properly sized MMCTECH destoner improves product purity, protects equipment, reduces maintenance costs, and increases plant efficiency.

How a Destoner Machine Works

A destoner machine separates materials based on density differences. Through a combination of vibration, airflow, and gravity separation, heavier contaminants move in a different direction than the product stream. This allows stones and dense foreign materials to be discharged separately while clean product continues to the next processing stage.

Frequently Asked Questions

What is a stone separator machine?

A stone separator machine removes stones and heavy impurities from grains, seeds, pulses, and food products.

What is a destoner machine used for?

Destoner machines remove stones, glass, metal fragments, and dense contaminants before further processing.

Which crops require destoning?

Wheat, rice, corn, lentils, chickpeas, beans, sesame, sunflower seeds, spices, and many other agricultural products.

How does a grain destoner work?

A grain destoner uses airflow, vibration, and density differences to separate heavier impurities from product.

Can a destoner remove metal particles?

Many dense metal contaminants can be removed, although magnetic separators may also be recommended.

Do I need a destoner before a color sorter?

Yes. Destoning improves sorter performance and protects expensive optical sorting equipment.

Can stone separators be integrated into existing plants?

Yes. MMCTECH machines can be installed into both new and existing processing facilities.
