What do I need to pay attention to before using a stone remover? I believe you are no stranger to the cleaning of stone removers. As the main equipment in the cleaning process, it plays an important role in removing stones from grains. In order to better exert its use value, it is necessary to pay attention to some details in the operation process. So, what do you need to pay attention to before using a stone remover?
1. Flow control: If the flow rate of the combined cleaning stone remover is too large or too small, it will reduce the stone removal efficiency. If the flow rate is too small and the particle layer on the sieve surface is too thin, it is easy to be broken by the air flow, and even blow up the mud, so that the air flow on the sieve surface is seriously uneven, resulting in unclear fruit separation; If the flow rate is too high, the particle layer is thicker and the stone particles cannot be fully graded, which also reduces the inefficiency of the device.
2. Air volume adjustment: judge the air volume of the stone remover according to the movement state of the material on the screen surface and the quality of the two products. When the air volume is too high, the material on the screen will not only float. This not only disrupts the automatic sorting, but also blows some flaky mud from the bottom of the layer and discharges it out of the mouth along with the rice.
3. Determination of the inclination angle of the sieve surface: Generally, the slope of the sieve surface should be mastered between 10 and 13 °. The slope is too large, the stone has a large resistance to upward movement, and the speed of entering the cleaning room is slow. At the same time, due to the increased velocity of the particles on the sieve surface, they may be washed away by the particles; When the angle is too small, although the upward movement resistance of the stone is small and easy to discharge, the particle movement speed on the screen surface is too slow, which affects the output, and the particle content in the stone will increase accordingly, so the slope of the screen surface should be kept appropriate.
4. The working screen surface should be smooth: the working screen surface should be flat without concave and convex phenomenon; After the protruding edge of the screen surface is worn, the screen plate can be turned over or replaced. When disassembling the screen surface, do not press the screen surface with heavy objects. Before starting, check whether the bearing seat is tightened, whether other important connecting screws are tightened, and a layer of material should be laid on the screen surface in advance, so as to avoid the material can not be paved on the screen surface in time when the machine is started, resulting in uneven airflow distribution. In the work, the situation of stones and stones should be checked frequently, and the cause of the problem should be found in time and the treatment measures should be taken.
