[0002] Ore washing machines are usually used to remove impurities from ores and improve the purity of ores. Their working principle is to separate light impurities such as soil, sand and stone from heavy minerals in ores through water flow or mechanical force. The ore washing process is crucial to improving mineral quality, reducing transportation costs and improving ore dressing efficiency.

[0003] After searching, the utility model patent with patent announcement number CN202823867U discloses a vibrating screening device for a ore washing machine, which uses a vibrating motor as a vibration source to throw the material on the screen and move forward in a straight line. The material enters the feed port of the screening machine evenly from the feeder, and passes through multiple screen sections to produce several specifications of oversize and undersize, which are discharged from their respective screen sections, thereby realizing multi-stage separation and comprehensive utilization of tailings, conventional ores, high-quality ores, etc. This device has low energy consumption, high output, simple structure, easy maintenance, and automatic discharging, which is suitable for large-scale production.

[0004] However, the above design still has some shortcomings.
