Description

A sorting device for mining

Technical field

The invention relates to the technical field of ore separation, and specifically refers to a sorting device for mining.

Background technique

The grade of the ore extracted during the mining process is reduced due to the mixing of waste rock or the loss of high-grade ore. In order to improve the grade of ore, the mined ore needs to be sorted. At present, the magnetic separator is one of the most widely used sorting devices.

However, in actual use, the ore is crushed before magnetic separation and then enters the magnetic separator. Since the ore cannot be completely uniform during crushing, the crushed ore often contains a small amount of large pieces that exceed the standard. These large pieces enter the magnetic separator tank. After being removed, it will cause damage to the magnetic plates adhered to the drum surface and reduce the service life of the magnetic separator.

At the same time, most of the magnetic separators in the existing technology can only perform one diversion, and the usage process is for the ore slurry to enter the cylinder from the feed tank and reach the bottom of the cylinder for diversion. During this type of use, the weight and quantity of the ore may vary. As a result, the ore selection magnet cannot be screened, making the iron selection efficiency of the magnetic separator low and the effect poor.
