Paddy Destoner Machine

When the specific Paddy Destoner Machine works, the material continues to enter the middle of the stone screen surface, due to the different density and aerodynamic characteristics of the components of the material, under the appropriate vibration and air flow, the less dense material floats on the upper layer, and the larger density stone sinks into the bottom and contacts with the screen surface, forming an automatic stratification.

Due to the bottom-up flow through the material, the porosity between the materials increases, the positive pressure and friction between the material layers are reduced, and the material is in a fluid state, which promotes the automatic stratification of the material.

Because the front of the stone screen is slightly inclined, the upper material is under the action of gravity, inertial force and continuous feed thrust, and the following layer of material is a sliding surface, which slides down to the net material outlet relative to the stone screen surface.

At the same time, gravel and other debris gradually separated from the material into the lower layer. The lower stone and the non-suspended heavy material slide back along the screen face under the action of vibration and screen surface structure and air flow.

The upper material is getting thinner and thinner, the pressure is reduced, the lower material continues to enter the upper layer, when the end of the screen surface is reached, the normal material in the lower stone has very little.

Under the action of reverse blowing air, a small amount of normal materials are blown back, and heavy objects such as stones are discharged from the stone discharge port.
