Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing and coal preparation, and particularly relates to a rotating ore dressing and grinding device. Background Art

[0002] Grinding can break the ore into appropriate particle sizes, enabling ore dressing equipment to more effectively process these particles. The finer the particle size, the greater the surface activity, which helps improve the efficiency of subsequent separation processes such as flotation, magnetic separation, and gravity separation.

[0003] According to the publication number: CN212167636U, a ball mill for ore dressing is disclosed, including a base, a telescopic rod, and a cylinder body. Above the base, there is a cylinder, and above the cylinder, there is a telescopic rod. Above the telescopic rod, there is a bracket, and inside the bracket, there is a cylinder body. In the middle of the cylinder body, there is a large gear, and inside the cylinder body, there is a lining. On one side of the cylinder close to the central axis of the base, there is a motor, and on the left side of the motor, there is a small gear. Inside the lining, there is a partition plate, and on the left and right sides of the partition plate, there are grinding media. At the upper end of the cylinder body, there is a qualified product discharge port, and on the right end of the qualified product discharge port, there is a hinge. On the right side of the hinge, there is a waste product discharge port. This ball mill for ore dressing is convenient for feeding, convenient for classifying the ground materials, discharging and collecting them separately, reducing the workload of subsequent classification, and increasing labor efficiency.

[0004] It can be seen that the grinding mechanism in the prior art is more convenient for discharging after ore grinding. However, before grinding, due to the large size of the ore, if it directly enters the grinding mechanism for grinding, it is easy to increase the load of the grinding mechanism, reduce the processing capacity, and increase energy consumption. Therefore, it is first necessary to preliminarily crush the ore to reduce the particle size of the ore. In order to transport the crushed ore into the grinding mechanism, it is necessary to connect the discharge port of the crushing mechanism with the feed port of the grinding mechanism. If a fixed seal connection is used, it is not convenient for subsequent disassembly and maintenance. If not connected, it is easy to cause ore splashing during feeding. Summary of the Utility Model

To simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numerals and / or reference letters in different examples.

[0034] To better understand the purpose, structure, and function of the present invention, the following further describes in detail a rotary ore dressing and grinding device of the present invention with reference to the drawings.

[0035] As Figures 1-8As shown in the figure, a rotating ore dressing and grinding device of the present utility model includes a grinding outer shell 1 rotatably installed on a bracket. A gear ring 3 is arranged on the outer side of the grinding outer shell 1. One side of the gear ring 3 is engaged with a driving wheel 4, and the driving wheel 4 is driven by a motor, so as to drive the grinding outer shell 1 to rotate by the gear ring 3. Since a plurality of grinding steel balls 2 are placed inside the grinding outer shell 1, when the grinding outer shell 1 rotates, the grinding steel balls 2 are lifted to a certain height and then fall, generating an impact force on the material and crushing large pieces of material into smaller particles.

[0036] In order to reduce the load of larger materials on the grinding mechanism, the feeding end of the grinding outer shell 1 is rotatably connected to the discharging port of a conveying outer shell 5. A receiving hopper 6 is arranged at the feeding port of the conveying outer shell 5, and the receiving hopper 6 is used to receive the materials falling from the discharging port of a processing shell 12. The processing shell 12 is erected on the upper side of the conveying outer shell 5 through a support frame 11.

[0037] Wherein, a conveying screw 7 is rotatably arranged inside the conveying outer shell 5. The conveying screw 7 is driven by a motor, and the conveying screw 7 can convey the materials fed from the processing shell 12 into the grinding outer shell 1.

[0038] In addition, a pair of crushing rollers 15 are rotatably arranged inside the processing shell 12. Rotating gears 14 are connected to the shafts at one ends of the pair of crushing rollers 15, and the two rotating gears 14 are engaged. The shaft at the other end of one of the crushing rollers 15 is connected to a transmission member 16, and the transmission member 16 is driven by a motor. When the materials enter between the two crushing rollers 15, the materials are preliminarily crushed by the rotation of the crushing rollers 15, making the particle size of the materials smaller.

[0039] Guide plates 13 are symmetrically arranged on the upper side of the processing shell 12, and the guide plates 13 guide the materials entering the processing shell 12 between the two crushing rollers 15.

[0040] Furthermore, a splash guard 17 is slidably arranged outside the discharging port at the lower end of the processing shell 12. When the splash guard 17 is in contact with the receiving hopper 6, it is used to prevent the materials from splashing when discharging.

[0041] As Figure 6 shown, slide rails 19 are symmetrically arranged on the lower side of the processing shell 12. The slide rails 19 are slidably connected to sliders 18 arranged on both sides of the splash guard 17. And a lead screw 20 is rotatably arranged inside one of the slide rails 19. The lead screw 20 is threadedly connected to the slider 18. By rotating the lead screw 20, the slider 18 drives the splash guard 17 to move up and down, ensuring that the splash guard 17 can stably contact the receiving hopper 6.

[0042] Meanwhile, symmetric positioning rods 21 are rotatably arranged on the border of the splash guard 17. When the splash guard 17 fits with the material receiving hopper 6, the positioning rods 21 are inserted into the jacks 8 opened on the upper side of the material receiving hopper 6. Since a positioning sleeve 9 is arranged on the lower side of the jack 8 and a positioning groove 10 is opened on one side of the positioning sleeve 9, a positioning block 22 arranged at the lower end of the positioning rod 21 is slidably connected with the positioning groove 10. After rotating the positioning rod 21, the positioning block 22 is rotated to one side of the positioning groove 10 to enhance the stability of the splash guard 17.

[0043] Working principle of a rotary ore dressing and grinding device: The guide plate 13 guides the material to the space between the two crushing rolls 15 for preliminary crushing. The crushed material enters the conveying outer shell 5, and is conveyed to the grinding outer shell 1 by the rotation of the conveying screw 7. The grinding steel balls 2 in the grinding outer shell 1 crush the material. When the material is discharged in the processing shell 12, the splash guard 17 is used to shield the material, and the splash guard 17 is flexibly fixed by the lead screw 20 and the positioning rod 21.

[0044] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
