The mineral resource development and utilization work plays an important role in national economy construction. Most metal mine concentrating mills in mineral resource development have ore grinding processes, and steel balls are used as ore grinding media to grind ores. The steel balls serve as grinding media to dissociate ore, but the steel balls can be reacted with continuous operation to reduce abrasion, and finally are discharged out of the ore grinding equipment. In addition, since the natural ore causes, it is difficult to further reduce the size of the ore which is ground to a certain size in the grinding process, and a relatively stable ore or gravel called "stubbles" is formed.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the device for vibrating and separating the magnetic stubborn stones and the steel balls structurally comprises a bottom frame 1, four height adjusting devices 2, four vibration absorbers 3, a separating plate 4, a vibration exciter 5, a separating guide plate 6, a stubborn stone collecting hopper 7 and a steel ball collecting hopper 8.
The height adjusting devices 2 are respectively and vertically arranged at four corners of the underframe 1; the height adjusting device 2 comprises a hydraulic cylinder. The height adjusting device 2 is composed of 4 sets of hydraulic devices which can work independently, wherein the actuating elements are hydraulic cylinders and are distributed on 4 corners of the underframe 1. The base of the hydraulic cylinder is arranged on the underframe 1, the hydraulic rod of the hydraulic cylinder extends upwards, and the hydraulic rod can move up and down and stay at a required position within a certain range under the action of the hydraulic system and the control system according to requirements, so that the height is changed.
The separating plate 4 is installed with a certain inclination angle in both the length and width directions, namely, with a space inclination. Respectively referred to as a longitudinal tilt angle and a transverse tilt angle. Adjusting the height of the four height adjustment devices 2 enables adjustment of the longitudinal inclination angle α and the transverse inclination angle β of the separation plate 4. Specific alpha is controlled at 0 to 30 degrees, beta is controlled at 0 to 25 degrees, and specific examples of specific developments may be alpha controlled at 15 degrees and beta controlled at 10 degrees. The angle of α and β can be changed by changing the mounting direction of the exciter 5 according to the specific gravity of the magnetic stubby stones to be separated and the like.
The height adjusting devices 2 are respectively provided with a shock absorber 3, and the shock absorbers 3 are compression springs. Respectively mounted on the hydraulic rod of each hydraulic device of the corresponding height adjusting device 2. The separation plate 4 is arranged on the four shock absorbers 3, and the lateral side surfaces of the separation plate 4 are longitudinally provided with baffle plates. Is used for preventing stubborn stones and steel balls from falling out.
The vibration exciter 5 is arranged at the middle part below the bottom of the separation plate 4. The vibration exciter 5 specifically comprises two vibration exciting motors rotating in opposite directions, and two ends of a central shaft of each vibration exciting motor are provided with eccentric masses with equal mass and same phase, so that the vibration exciter 5 can provide linear vibration along the normal direction of a base mounting plane.
In this example, the vibration exciter 5 is installed at the middle position of the separating plate 4 in a space inclined manner, the separating plate 4 transversely refers to the left-right width direction, and an included angle gamma is formed between the vibration direction of the vibration exciter 5 and the normal direction of the plane of the separating plate 4; the projection of the vibration direction of the vibration exciter 5 on the separation plate 4 forms an included angle delta with the transverse direction of the separation plate 4. Specific gamma is controlled to 0 to 30 degrees, delta is controlled to 0 to 45 degrees, and specific examples in development may be gamma controlled to 20 degrees, delta controlled to 25 degrees. When the vibration exciter 5 is mounted, as shown in fig. 2 and 3, an included angle gamma is formed between the vibration exciter and the plane of the separation plate 4, and an included angle delta is formed between the vibration exciter and the longitudinal direction of the separation plate. So that the vibration direction of the separating plate 4 forms an angle y with the normal direction of the separating plate 4 plane, and the projection of the vibration direction of the separating plate 4 onto the separating plate 4 plane forms an angle delta with the width direction of the separating plate 4. The angle of γ and δ can be changed by changing the mounting direction of the exciter 5 according to the specific gravity of the magnetic stubby stones to be separated and the like.
The longitudinal inclined front end feed inlet of the separation plate 4 is higher than the rear end discharge outlet, and has a longitudinal inclination angle alpha. The longitudinal direction of the separation plate 4 refers to the longitudinal direction in the front-rear direction.

The separation plate 4 is inclined transversely, has different left and right heights and has a transverse inclination angle beta. The lateral inclined magnetism stubborn stone discharging hole side of the separating plate 4 is higher than the steel ball discharging hole side. The magnetism stubborn stones which move forwards and backwards are separated from the steel ball vibration exciter 5 left and right under the action of the magnetism stubborn stones, and are respectively discharged from a magnetism stubborn stone discharge hole to fall into a stubborn stone collecting bucket 7 or are discharged from a steel ball discharge hole to fall into a steel ball collecting bucket 8.
The separation plate 4 vibrates under the action of the vibration exciter 5 and the vibration damper 3. After being conveyed onto the separating plate 4 from the feeding hole, the stubborn stones and the steel balls discharged from the ore grinding equipment are subjected to the vibration action of the separating plate 4 to move, and the stubborn stones and the steel balls are gradually separated from each other under the action of the vibration, the included angles of the vibration direction and the separating plate and the inclination angle action of the separating plate 4 due to obvious specific gravity difference of the stubborn stones and the steel balls, the stubborn stones and the steel balls gradually gather to move towards one transverse direction and fall into the stubborn stone collecting hopper 7, and the steel balls gradually gather to move towards the other transverse direction and fall into the steel ball collecting hopper 8, so that the separation of the magnetic stubborn stones and the steel balls is realized.
In addition, the method and the device for separating the magnetic refractory stone and the steel balls by the local vibration can also be used for separating the useful ore and the useless gangue when the specific gravity of the useful ore particles and the specific gravity of the useless gangue particles are obviously different in some concentrating mills.
