Improve the effect of the stone machine process needs to understand the working principle

The stone removal machine is an essential equipment for removing debris from the flour mill. It is mainly used to remove wheat grains mixed with wheat seeds to reduce the amount of sand in the flour and ensure the quality of the flour. If you don't know the working principle and operation of the stone machine, it is undoubtedly not conducive to improving the process effect of the stone machine. Next, let's look at the small series for detailed analysis and look down together.

The main working organization of the stone machine. After the material enters the stone screening surface, the material penetrates into the surface of the stone screen. Due to the different suspension rate of the shoulder stone and wheat, the wheat sinks at a lower suspension rate, and under the joint action of the full vibration and floating of the top layer, the shoulder suspension The stone sinks at a higher suspension rate. Particles are automatically formed near the bottom of the sieve surface classification phenomenon, and due to air flow, the material between the porosity increases, and the positive pressure and friction between the layers decrease. This further promotes the formation of an automatic gradation in the fluidized state. Under the action of gravity and inertial force, the upper layer material has a small suspension speed, moves to the airflow and continuously feeds the layer material as a sliding surface, except for the negative value of the wheat surface relative to the stone screen surface, the lower layer material is in the process. The stone and other debris in the integrated suspension are gradually suspended from the underlying layer. The lower surface of the sliding image and the gravel do not suspend the wheat under vibration, and the suspended wheat enters the upper layer at a semi-continuous speed. At the top of the stone, the material below contains almost no wheat. These wheats are blown back into the wheat stream under the influence of the return air, and the shoulder stones continue to climb and leave the stone exit.
