1. Drying the material: If the material has high humidity, it can easily lead to particle agglomeration or adhesion to the screen mesh, affecting the sieving effect. Reducing the material humidity through drying treatment can improve particle dispersion and facilitate sieving. For example, before sieving damp flour, it can be dried at a low temperature.
2. Suitable screen mesh: Select a screen mesh with accurate mesh size, appropriate shape, and wear-resistant material based on the characteristics of the powder and the sieving requirements. For high-precision sieving, Jianyuanda's
ultrasonic vibrating screen can use stainless steel woven mesh.
3. Adjusting vibration frequency and amplitude: For vibrating screens, the optimal combination of vibration frequency and amplitude should be found based on the material characteristics and screen specifications. Generally, higher frequency and smaller amplitude are used for fine particle powders; lower frequency and larger amplitude are used for coarse particle powders.
4. Controlling the feeding speed: A uniform and appropriate feeding speed is key to ensuring sieving efficiency. Too fast a feeding speed will cause material to accumulate on the screen surface, preventing sufficient sieving; too slow a feeding speed will reduce output. The feeding speed needs to be adjusted according to the processing capacity of the sieving equipment.
5. Timely cleaning of the screen mesh: During the sieving process, the screen mesh is prone to clogging or wear, requiring regular shutdown for cleaning. Methods such as back-blowing and vibration cleaning can be used to remove particles and impurities from the screen mesh and restore its permeability.
6. Checking equipment components: Regularly check all components of the ultrasonic vibrating screen, such as the ultrasonic generator and ultrasonic transducer, to ensure that the equipment is in good working condition. If any components are damaged, replace them promptly to avoid affecting the sieving effect.
