A De-stoner is an equipment that removes stones and clods from grains using the principle of density difference.
De-stoners are usually vacuum type and are equipped with vibro motors, fan and cyclone fitted RAV.
Its construction consists of a sieve box that directly holds the sieves, which are subjected to continuous vibration. The difference in density separates heavier fractions like stones, metallic particles, and pieces of glass from the grain.
