The electromagnetic high-frequency vibrating screen is a new type of screening machine that has obtained a national patent. The screen adopts a new principle design and a novel structure, which is suitable for dry and wet screening of various materials. Its structural characteristics and working principle are as follows: the vibrating arm arranged under the screen is driven by a vibration system mainly arranged on the outside of the screen box, which is based on an electromagnetic exciter. The vibrating arm is equipped with a rubber cap along the full width of the screen surface. Hold the screen and vibrate the screen. Each screen machine is arranged longitudinally with several groups of vibration systems, which are centrally controlled by an electric control box. Each group of vibration systems independently drives the vibrating arm to vibrate the screen, and the amplitude can be adjusted in sections at any time. The screen adopts folding hooks at both ends and is installed with longitudinal tension. The installation of the screen surface has a certain inclination and is adjustable. The material flows, stratifies and penetrates the screen under the action of its own weight and high-frequency vibration of the screen surface.
The high-frequency vibrating screen is mainly used in the coal preparation plant for the dehydration and recovery of coarse and fine slime. It can also be used for the ash reduction of flotation products and the coarse separation before flotation. It is used in the de-intermediation of the heavy-medium coal preparation process and the slime water treatment system. , High-frequency vibrating screen has also been successfully applied. In addition, in the simple coal preparation plant, the high-frequency vibrating screen recovers low-ash clean coal from the slime water and has also achieved higher economic benefits.
