TQSF destoner is applied for efficient separation of stones and pebbles, glass, and other high-density impurities from grain or seed.

TQSF Destoner is the suction type destoner, and its work principle is based on the difference in specific weight of materials. The working table is covered with a woven wire mesh bed, through which air flows from below. Heavy impurity such as stone are not lifted by the air cushion and stay on the mesh bed. The vibratory motion of the table causes the heavy impurity transported to the beginning of the regulating plate at far end of the machine.plate at far end of the machine.
