Stone Destoner Machine

A Stone Destoner Machine is a high-efficiency cleaning machine used in grain processing plants to remove stones, sand, mud balls, and other heavy impurities from food grains. The machine works on the principle of density difference combined with vibration and controlled airflow. As the mixture of grains and impurities passes over the vibrating deck, lighter grains move in one direction while heavier materials such as stones move in the opposite direction and are discharged separately. This process ensures effective separation without damaging the grains. Stone Destoner Machines are widely used for cleaning products such as rice, wheat, pulses, maize, spices, and seeds before further processing. Built with a strong and durable structure, the machine offers stable performance, high capacity, and easy maintenance. By efficiently removing unwanted impurities, the Stone Destoner Machine improves product purity, protects downstream processing equipment, and enhances overall productivity in modern grain processing industries.
