Emery stones are circular grinding components used in atta chakki (flour mill) machines to grind grains such as wheat, rice, maize, pulses, and spices. These stones are manufactured using a mixture of abrasive emery grains and bonding materials, ensuring high hardness, durability, and efficient grinding performance.
In a typical chakki system, two stones are used—one stationary and one rotating. The friction between them grinds the material into fine flour while maintaining low heat generation, which helps preserve the nutritional value and natural taste of grains.
