Gravity Destoner

The princple of the machine:
It is based on the proportion of grain crop and cobble density differences, by adjust the pressure and vibration frequency separate the stone and grain. The machine is equipped with a multi blade fan with high accuracy,The lighter grain crops will be suspended state, and the larger proportion of the stones will cling to the stainless steel mesh by adjusting the air pressure, and then by adjusting the frequency that Stoner table vibrates so as to achieve the purpose of separation. The machine equipped with frequency conversion control device can be subtle regulation, even if the proportion of the difference is very small, stones also will be separated.
