Its design and quality directly affect the screening efficiency and the purity of the screened product. The main function of the vibrating screen plate is to carry the material and to stratify and screen the material under the action of vibration, thereby achieving the screening purpose. In order to prevent leakage through the screen plate gap, the screen plate usually adopts a special design and material. First, the width of the screen plate gap needs to be precisely designed according to the particle size and characteristics of the screened material to ensure that the material can pass through the screen smoothly while preventing fine particles from leaking from the gap.
