Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating screens, and specifically relates to a material-breaking type vibrating screen. Background Art

[0002] A vibrating screen is a commonly used vibrating sieving device. Its working principle is mainly to use a vibrating motor on the vibrating screen to generate vibration, and vibrate and screen the ore material fed on the sieve. During the sieving process, the ore material with large particle size is intercepted, and the fine ore material with small particle size passes through the sieve. During the working process, the vibrating screen sieves the ore material while refining it. The refining process is to use the vibration of the ore material to generate crushing and pass the refined ore material through. However, the disadvantages of this method are also very obvious. For ore materials with slightly higher hardness, it is not easy to refine the ore materials during the vibration process. During the working process of the vibrating screen, the feeding speed is not easy to control, and the situation of material accumulation is likely to occur, resulting in the discharge from the discharge port before thorough screening and poor screening effect.

[0003] In view of this, the present utility model is specifically proposed. Summary of the Utility Model
