DETAILED DESCRIPTION

[0035] Preferred embodiments of the present application will be described in detail below with reference to the attached drawings. It will be appreciated that the description is merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present application.

[0036] It should be noted that similar reference numerals refer to similar items throughout the attached drawings, and once an item is defined in one drawing, it can not be further defined and explained in subsequent drawings.

[0037] The embodiment mainly describes the structure of a fine grinding machine for mineral processing, and specifically as follows:

[0038] As Figures 1-16As shown, a fine grinding machine for mineral processing includes a mounting seat 1 and a mounting column 2 mounted on the mounting seat 1, then a rack 8 and an adjusting assembly 3 engaged with the rack 8 are arranged on the mounting column 2, and the adjusting assembly 3 is sleeved on the mounting column 2, and the adjusting assembly 3 can move along the rack 8 on the mounting column 2 through cooperation with the rack 8, and a scale 10 is arranged on the side wall of the mounting column 2, and the scale 10 is located inside the adjusting assembly 3, then a stirring assembly 4 is arranged on the adjusting assembly 3, and an open-topped grinding cylinder 6 is arranged on the mounting seat 1 below the stirring assembly 4, so that when the grinding machine is working, first, the distance between the bottom of the adjusting assembly 3 and the bottom of the grinding cylinder 6 is adjusted according to the diameter of the grinding medium to be added, and when the adjusting assembly 3 is moved, the moving distance of the adjusting assembly 3 on the mounting column 2 can be intuitively understood due to the arrangement of the scale 10, so that the distance of the adjusting assembly 3 moving on the mounting column 2 is facilitated, thereby the distance between the stirring rod 42 and the bottom of the cylinder can be quickly adjusted, which shortens the adjustment time and improves the efficiency of mineral grinding. After the distance of the stirring assembly 4 is adjusted, ceramic balls as grinding medium and minerals to be ground are added into the grinding cylinder 6, and then the stirring assembly 4 is started to stir and grind the grinding medium and the minerals to be ground in the grinding cylinder 6;

[0039] In order to avoid the scale 10 from being worn when the adjusting assembly 3 moves, a first mounting groove 9 is formed in the side wall of the mounting column 2, and the scale 10 is mounted in the first mounting groove 9, and when the scale 10 is mounted in the first mounting groove 9, the top of the scale 10 is lower than the top of the first mounting groove 9, so that when the adjusting assembly 3 moves on the mounting column 2, the scale will not be worn, thereby prolonging the service life of the scale 10.

[0040] The adjusting assembly 3 includes a mounting block 32, and a recess 321 matched with the mounting column 2 is formed in the mounting block 32, and the mounting block 32 is slidably mounted on the side wall of the mounting column 2 provided with the rack 8 through the recess 321, and a first limiting groove 322 engaged with the rack 8 is arranged on the groove wall of the recess 321, and a through groove 323 is formed in the side wall of the recess 321 close to the rack 8, then a pressing block 33 connected with the mounting block 32 by bolts is arranged on the side of the mounting column 2 away from the mounting block 32, and an elastic pad 36 is arranged between the connection between the pressing block 33 and the mounting block 32, and a mounting bracket 31 for mounting the stirring assembly 4 is arranged on the side of the pressing block 33 away from the mounting block 32, and finally a gear box 34 is arranged on the outer wall of the mounting block 32, and the inside of the gear box 34 is communicated with the through groove 323, and a gear 37 engaged with the rack 8 is rotatably arranged in the gear box 34, and in order to facilitate the rotation of the gear 37 in the gear box 34, an adjusting wheel 35 connected with the gear 37 is rotatably arranged on the side wall of the gear box 34.

[0041] When the staff controls the adjusting assembly 3 to move on the installation, the staff rotates the adjusting wheel 35 to make the gear 37 connected with the adjusting wheel 35 start to rotate in the gear box 34, and since the gear 37 is engaged with the rack 8 through the through groove 323, the installation block 32 and the pressing block 33 can drive the mounting frame 31 to move on the installation column 2 along with the rotation of the gear 37, so the stirring assembly 4 can be driven to move along with the movement of the mounting frame 31;

[0042] In order to ensure the stability of the installation block 32 when it moves on the installation column 2, the first limiting groove 322 is arranged on the groove wall of the recess 321 to be clamped with the rack 8, and the installation block 32 is connected with the pressing block 33 through bolts, which facilitates the disassembly and assembly of the installation block 32 and the pressing block 33, thereby facilitating the maintenance and replacement of the rack 8 and the adjusting assembly 3. The elastic pad 36 arranged between the pressing block 33 and the installation block 32 can reduce the gap between the rack 8 and the gear 37 due to wear after a long time of use, so that the adjusting assembly 3 can be prevented from shaking when it moves on the installation column 2, and the accuracy of the movement of the adjusting assembly 3 on the installation column 2 can be improved. When the gap between the rack 8 and the gear 37 is too large, the bolts can be tightened to press the elastic pad 36 tightly, so that the gap between the pressing block 33 and the installation block 32 is reduced, and the gap between the rack 8 and the gear 37 is also reduced, thereby ensuring the stability and accuracy of the adjusting assembly 3 on the installation column 2 after a long time of use.

[0043] In order to avoid the problem of left and right shaking of the adjusting assembly 3 when it moves on the installation column 2, the limiting strip 21 is arranged in a V-shaped manner on the side of the installation column 2 close to the pressing block 33, and the second limiting groove 331 is arranged on the pressing block 33 to match the limiting strip 21, thereby further improving the stability and accuracy of the adjusting assembly 3 when it moves on the installation column 2.
