Technical Field

[0001] The utility model belongs to the technical field of lead-zinc ore screening, and particularly relates to a screening device for lead-zinc ore mining. Background Technique

[0002] Lead-zinc ore is a mineral rich in metal elements lead and zinc. Lead-zinc has a wide range of uses and is used in fields such as the electrical industry, mechanical industry, military industry, metallurgical industry, chemical industry, light industry, and pharmaceutical industry. After the mined lead-zinc ore is broken.

[0003] The broken lead-zinc ore needs to be screened by a screening machine. During the screening process, since it is discharged from the discharge port after being broken, a stacking situation will occur on the screen frame, thereby reducing the screening effect. For this reason, we propose a screening device for lead-zinc ore mining, which can push back and forth at the stacking place to avoid stacking to solve the above-mentioned deficiencies.
