Operating instructions of the specific gravity machine

The specific gravity machine is an important equipment used to process seeds and agricultural and sideline products. It can be used to process various dry granular materials and make full use of the comprehensive effects of airflow, vibration and friction on the materials. Vibration and friction move to a high place, and the material with a small specific gravity is suspended on the surface of the material layer and flows to a low place through the action of the air flow, so as to achieve the purpose and separate by specific gravity.

The principle of specific gravity segregation under the dual effects of vibration and friction. By adjusting technical parameters (such as wind pressure and amplitude), materials with a larger specific gravity will sink to the bottom and move from low to high to the surface of the screen. Materials with low specific gravity are suspended on the surface from high to low to achieve the purpose of separating specific gravity. It can effectively remove lighter weight impurities such as corn seeds, germinated seeds, borer grains, moldy grains and powdery mildew grains. Increase the side grain output function, increase the grain output; at the same time, the upper part of the sorter vibration table is equipped with a stone removing slope, which can separate the stones in the material.

The operation instructions of the specific gravity machine are as follows:

Before starting, a comprehensive inspection of the special gravity machine must be carried out, such as whether the pressure door and the suction pipe adjustment damper of the oil storage tank can be flexibly rotated, and the reverse adjustment version is easy to adjust. When starting, please close the air door first, after the fan runs, slowly open the air door and start feeding paper at the same time.

1. Adjust the main baffle so that the material covers the second layer and moves in a wave-like boiling state.

2. Adjust the blowback door at the stone exit to control blowback, so that the stone and the material form a clear boundary (the area of the stone is usually about 5cm), the stone is normal, and the grain content in the stone meets the requirements, that is, it works normally Under certain conditions, the blowback valve should be about 15-20cm away from the screen surface.

3. Adjust the supplementary air according to the boiling state of the material.

4. When stopping, stop feeding first, then stop, and turn off the fan to prevent materials from accumulating on the surface of the sieve and causing blockage on the surface of the sieve, thereby affecting normal operation. 

5. Regularly clean the surface of the sieve to remove stones to prevent clogging the sieve of the hydrometer, and regularly check the degree of wear on the surface of the sieve. If the wear is too large, the surface of the screen should be replaced in time to avoid affecting the stone removal effect.

The above is the detailed operation instructions of the hydrometer. Thank you for your attention and support. If you want to know more, please follow the official website of Yongming Machinery. See you next time!
