Description

Technical field:

[0001] The utility model relates to the field of lead-zinc ore dressing, in particular to a lead-zinc ore slurry slag removal device. Background technology:

[0002] Lead-zinc ore is a mineral rich in the metal elements lead and zinc. Lead and zinc are widely used in the electrical industry, mechanical industry, military industry, metallurgical industry, chemical industry, light industry and pharmaceutical industry. In addition, lead metal is also widely used in the nuclear industry, petroleum industry and other sectors. my country's lead-zinc mines are mainly concentrated in Yunnan, Inner Mongolia, Gansu, Guangdong, Hunan and Guangxi.

[0003] In the process of lead-zinc ore beneficiation, minerals (ore, etc.) are transported to the ground through conveyors in the mine, and then go through processes such as crushing, primary selection, and flotation until they meet the requirements. During this process, the ore is transported by conveyors.

[0004] During the mining process, the detonating cords from blasting operations are mixed in the ore and cannot be picked out. Through ore dressing crushing and ball milling operations, impurities are formed and mixed in the ore slurry. If effective measures are not taken to screen them out, it will seriously affect the subsequent ore dressing production. For example, the air distributor of the flotation machine is blocked, resulting in insufficient or uneven air supply for the flotation operation, which leads to unstable flotation liquid level and affects production indicators; the detonating cords are deposited at the bottom of the middle phase of the flotation machine, blocking the cone valve hole, resulting in poor circulation of the intermediate ore and affecting the separation indicators; some detonating cords are mixed in the concentrate, affecting the accuracy of concentrate sampling.

[0005] Therefore, a structure is needed to screen out the broken detonating cords. Utility model content:

[0006] The utility model aims to provide a lead-zinc slurry slag removal device.

[0007] The utility model is implemented by the following technical solutions:
