grain destoner technical analysis and manufacturing specifications
Stainless steel magnetic separators remove metals, soil blocks, and clods from grains and beans with a 5–10 TPH capacity. Built for food-grade purity, the equipment is available as 5–10 TPH systems for efficient pre-cleaning and uses SGS- and CE-certified components.
The High-Performance Magnetic Separator is a specialized industrial solution designed to remove clods, soil blocks, and ferrous contaminants from a wide range of grains and pulses. Using advanced magnetic attraction principles, the system ensures that agricultural products such as wheat, corn, and beans are purified to the highest standards—helping prevent damage to downstream equipment and supporting food-grade purity.
Built for versatility and efficiency, this machine uses a powerful magnetic roller and an adjustable belt system to achieve precise separation between organic material and inorganic impurities. Whether integrated into a large-scale seed processing plant or a small coffee bean cleaning facility, our magnetic separator delivers reliable performance in removing soil blocks and metallic debris.

It is suitable for wheat, corn, soybeans, mung beans, kidney beans, chickpeas, coffee beans, peanuts, and maize seeds.
The machine uses a powerful magnetic roller. Because of the difference in attraction strength between grains and soil clods/magnetic debris, they are separated physically on the belt.
Yes. It is equipped with an advanced frequency converter that allows you to adjust belt speed to optimize separation for different materials.
Yes. Key components and contact surfaces are made of 304 stainless steel, supporting food-grade cleaning and hygiene requirements.
We use a specialized low-speed, non-broken slope elevator to transport seeds and beans gently to the separator without mechanical impact.
The magnetic roller provides a field strength of more than 18,000 Gauss, designed to remove almost all ferrous material from the product.
