Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for separating micro-ore. Background Art

[0002] Micro-mineral separation refers to the process of separating tiny mineral particles from raw materials. It is of great significance in ore processing and beneficiation, because many valuable minerals often exist in the form of fine particles. The main goal of micro-mineral separation is to separate tiny mineral particles from other impurities to improve the recovery rate and purity of the ore.

[0003] The original ore is crushed and ground to make its particle size suitable for subsequent separation operations. The ore is classified according to particle size through screening or centrifugal classification to separate larger and smaller particles. This requires the use of two sets of equipment for grinding and screening, which increases the process and cost of transfer processing. For this reason, we propose a grinding device for micro-ore separation to solve the existing problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] like Figure 1-Figure 4 As shown, the present invention provides a grinding device for separating micro-ore, comprising a grid cylinder 2, a base 6, a pressure roller 12 and a motor 10.

[0048] The pressure rollers 12 are symmetrically distributed above the base 6;

[0049] The outside of the pressure roller 12 is sleeved with a grid cylinder 2;

[0050] The outer wall of the grid tube 2 is sleeved with a screen 19;

[0051] A material trough 9 is provided inside the upper end of the grid tube 2;

[0052] The outer side of the base 6 is sleeved with an outer cover 1;

[0053] A motor 2 10 is arranged on one side of the grid tube 2, a gear 11 is arranged on one end of the motor 2 10, a mounting ring 17 is sleeved on the outer wall of one side of the grid tube 2, a gear ring 7 is sleeved on the outer wall of the mounting ring 17, and the gear 11 and the gear ring 7 are meshed with each other;

[0054] The outer wall of the grid tube 2 is sleeved with equidistantly distributed mounting rings 17, and the upper end of the base 6 is provided with equidistantly distributed rotating frames 13, which include:

[0055] Support legs, located on both sides of the lower end of the rotating frame 13;

[0056] The arc seat is located outside the lower end of the grid tube 2;

[0057] A guide rail is provided inside the arc seat, and the mounting ring 17 is rotatably mounted inside the guide rail;

[0058] The lower end of the support foot is connected to the base 6 .

[0059] Both ends of the pressure roller 12 are provided with mounting shafts 3;

[0060] Both sides of the upper end of the base 6 are provided with symmetrically distributed bearing brackets 5;

[0061] A motor 8 is provided at one end of the mounting shaft 3;

[0062] Among them, the output end of the motor 8 is connected to the mounting shaft 3;

[0063] The mounting shaft 3 is rotatably mounted inside the bearing bracket 5 .

[0064] Limiting plates 18 are provided at both ends of the grid tube 2;

[0065] The limiting plate 18 is annular and hollow inside;

[0066] The material trough 9 passes through the limiting ring, and is inclined, with the end thereof being located at the center above the two pressing rollers 12 .

[0067] The implementation steps of the embodiment are as follows: the motor 8 operates to drive the pressing roller 12 relative to the lower end, and the material trough 9 conveys the raw material to the middle of the pressing roller 12. The extrusion force during the relative rotation presses and grinds the raw material. The qualified raw material passes through the holes inside the grid cylinder 2, is discharged to the outside through the screen 19, and is intercepted by the outer cover 1, gathered at the upper end of the base 6, and is discharged through the discharge port 16, and the raw material that is not completely ground is retained inside the grid cylinder 2;

[0068] The operation of motor 2 10 drives gear 11 to rotate, and gear 11 drives gear ring 7 to rotate, so that grid cylinder 2 rotates, and material removal plate 20 takes the uncompleted ground raw materials to a high place and pours them between pressure rollers 12 for secondary grinding, thereby realizing automatic loading of uncompleted ground raw materials. The grinding and screening devices are used in combination to avoid the transportation process and reduce the cost during the transportation process. Correspondingly, the two sets of grinding and screening equipment occupy less site space.

[0070] The lower end of the base 6 is provided with a supporting leg;

[0071] The supporting legs are located at the four corners of the lower end of the base 6;

[0072] A discharge port 16 is provided inside the lower end of the base 6;

[0073] The lower end of the outer cover 1 is connected to the base 6;

[0074] The outer cover 1 is in the shape of a tunnel.

The brush bar 14 is a flexible structure and can effectively pass through the material shifting plate 20. After passing through the material shifting plate 20, the inner wall of the screen 19 is scraped, and the raw materials clogged inside the screen 19 are separated, thereby improving the permeability of the screen 19 during use and extending the cleaning and maintenance cycle of the screen 19.
