Operating instructions for the specific gravity machine

The specific gravity machine is an important equipment used for processing seeds and agricultural products. It can be used to process various dry granular materials, fully utilizing the comprehensive effects of airflow, vibration, and friction on the materials. Vibration and friction move upwards, and materials with lower specific gravity are suspended on the surface of the material layer and flow downwards through the action of airflow, thereby achieving the goal of specific gravity separation.

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 higher specific gravity will sink to the bottom and move from low to high to the surface of the sieve. 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 impurities such as corn seeds, germinated seeds, insect infested grains, moldy grains, and powdery mildew grains. Increase the lateral grain yield function and increase grain yield; At the same time, the upper part of the sorting machine vibration table is equipped with a stone removal slope, which can separate the stones in the material.

The operating instructions for the specific gravity machine are as follows:

Before starting, it is necessary to conduct a comprehensive inspection of the dedicated gravity machine, such as whether it can flexibly rotate the pressure valve of the oil storage tank and adjust the suction pipe damper, and whether the reverse adjustment version is easy to adjust. When starting, please close the air door first. After the fan is running, slowly open the air door and start feeding at the same time.

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

2. Adjust the anti blowing door at the stone outlet to control the anti blowing, so that a clear boundary is formed between the stone and the material (the stone area is usually about 5cm). The stone is normal, and the grain content in the stone meets the requirements. Under certain conditions, the anti blowing valve should be about 15-20cm away from the surface of the sieve.

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

4. When stopping, the feeding should be stopped first, then stopped again, and the fan should be turned off to prevent the material from accumulating on the surface of the sieve and causing blockage, thereby affecting normal operation. .

5. Regularly clean the surface of the sieve to remove stones, in order to prevent clogging of the sieve holes of the densitometer, and regularly check the degree of wear on the sieve surface. If the wear is too great, the surface of the sieve should be replaced in a timely manner to avoid affecting the stone removal effect.
