Automatic Magnetic Destoner

Automatic Magnetic Destoner

An Automatic Magnetic Destoner is an advanced industrial machine used for the continuous removal of heavy impurities such as stones, glass, and metal particles from grains, spices, pulses, seeds, rice, and other granular materials. These machines work on the principle of magnetic separation and gravity separation to clean the raw material efficiently.

Automatic Magnetic Destoners are widely used in food processing, flour mills, rice mills, spice plants, chemical industries, and more. With automatic feeding, adjustable magnetic intensity, and dust-free operation, these machines ensure product purity, protect downstream equipment, and enhance final product quality.

Top manufacturers design them with SS construction, rare earth magnets, vibratory feeders, and energy-efficient motors for long-lasting, maintenance-free operation.
