The relationship between the angle of the sunflower screening machine screen and the yield is mainly reflected in the screening efficiency and material passing rate, which in turn affects the overall yield. The following is a detailed analysis of this relationship:

1、 The influence of screen angle on screening efficiency

The inclination angle of the sieve surface (i.e. sieve angle) is closely related to the productivity and screening efficiency of the sieve. The efficiency of screening depends on multiple factors, one of which is the inclination angle of the screening surface. Generally speaking, the size of the inclination angle of the screen surface will affect the movement speed and residence time of the material on the sieve, thereby affecting the screening effect.

Moderate inclination angle: When the angle of the sieve is moderate, the material can maintain a certain movement speed on the sieve, neither too fast causing insufficient screening nor too slow causing material accumulation. This can ensure screening efficiency and avoid screen clogging, thereby increasing production.

Excessive inclination angle: If the angle of the sieve is too large, the movement speed of the material on the sieve will accelerate, which may lead to insufficient screening. Some materials may be discharged without sufficient screening, reducing screening efficiency. At the same time, excessive inclination angle may also increase the crushing rate of materials, which is particularly unfavorable for fragile materials such as sunflower seeds.

Too small inclination angle: On the contrary, if the angle of the sieve is too small, the movement speed of the material on the sieve will slow down, and it may even cause the material to accumulate on the sieve, resulting in blockage of the sieve. This will not only reduce screening efficiency, but also increase equipment maintenance costs and time.

2、 The Influence of Screen Angle on Material Passing Rate

The angle of the sieve can also affect the pass rate of the material, thereby affecting the yield.

Optimizing the angle to improve the pass rate: By adjusting the screen angle, the movement trajectory and residence time of materials on the screen can be optimized, thereby improving the pass rate of materials. When the angle of the sieve is appropriate, the material can smoothly pass through the sieve, reducing blockage and retention, and increasing production.

Avoid extreme angles: Similar to screening efficiency, excessive screen angles may cause materials to pass through the screen too quickly and result in insufficient screening; A too small angle of the sieve may lead to material accumulation and blockage. Therefore, when selecting the angle of the sieve, it is necessary to avoid extreme values to ensure smooth passage of materials and efficient screening.

3、 Suggestions for practical applications

In practical applications, in order to improve the output and screening efficiency of sunflower screening machines, it is recommended to choose the appropriate screen angle based on the characteristics of the material and screening requirements. Meanwhile, the following points should also be noted:

Regular maintenance of the sieve: Regularly clean impurities and blockages on the sieve to keep it unobstructed.

Adjust the feeding method: Reasonably adjust the feeding method and amount to avoid material accumulation and clogging of the sieve.

Monitoring screening effect: Regularly monitor the screening effect, adjust the screen angle and other parameters according to the actual situation to ensure greater screening efficiency and output.

In summary, the relationship between the angle of the sunflower screening machine sieve and yield is closely related. By optimizing the screen angle, screening efficiency and material throughput can be improved, thereby increasing production. In practical applications, it is necessary to select the appropriate screen angle based on the characteristics of the material and screening requirements, and pay attention to regular maintenance and monitoring of the screening effect.
