Problems solved by technology
The ore is crushed before magnetic separation, and then enters the magnetic separator. Since the ore cannot be completely uniform when crushed, the crushed ore often contains a small amount of large pieces that exceed the standard. After these large pieces enter the tank of the magnetic separator, they will The magnetic plates stuck on the surface will cause damage, which reduces the service life of the magnetic separator, and the large impact sound is loud, resulting in high noise

Embodiment Construction
[0014] Embodiments of the present invention are further described below in conjunction with accompanying drawings:
[0015] like figure 1 As shown, the present embodiment comprises magnetic separator 3, vibrating screen 5, by vibrating screen 5, the excess bulk in the raw material ore is screened out, and conveying device 4 is set between magnetic separator 3 and vibrating screen 5, and conveying device 4 is Conveyor belt driven by roller table, one end of the conveying device 4 is set at the entrance of the magnetic separator 3, and the other end is set under the vibrating screen 5, the angle between the vibrating screen 5 and the horizontal plane is 45°, the feeding pipeline 1 is set above the vibrating screen 5, and the vibrating screen 5 is excited by the vibrator 3 .
[0016] When working, the raw ore enters the vibrating screen 5 through the feed pipeline 1, and the vibrating screen 5 screens the raw ore under the action of the vibrator 2, and the large pieces that exce...

The invention relates to an ore separation device and belongs to the field of industrial devices. The ore separation device comprises a magnetic separator, wherein a vibrating screen is arranged at an inlet of the magnetic separator, a feeding pipeline is arranged above the vibrating screen, and an included angle between the vibrating screen and the horizontal plane is 0-60 degrees, preferably 45 degrees. The vibrating screen is arranged close to the inlet of the magnetic separator, so that the service life of the magnetic separator is prolonged, the maintaining ratio of the device is reduced, the device operation rate is improved, the risk ratio of operation failure of operators is reduced, and the potential safety hazard is reduced.
Description
technical field [0001] The invention relates to an ore sorting device, which belongs to the field of industrial equipment. Background technique [0002] 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, it is necessary to separate the mined ore. At present, magnetic separator is one of the most widely used separation devices. The ore is crushed before magnetic separation, and then enters the magnetic separator. Since the ore cannot be completely uniform when crushed, the crushed ore often contains a small amount of large pieces that exceed the standard. After these large pieces enter the tank of the magnetic separator, they will The magnetic plates stuck on the surface will cause damage, which reduces the service life of the magnetic separator, and the large impact sound is loud, resulting in high noise. Contents of the invention [0003] According to th...
