Description

Technical Field

[0001] The utility model relates to the technical field of ore grinding, in particular to an ore tower mill device. Background Technique

[0002] An ore tower mill is a device specifically used for ore grinding, usually used for fine grinding of ore to improve the quality of concentrate. The existing structure of an ore tower mill includes a vertical cylinder body, grinding media and a stirring device installed inside the cylinder body. Its basic principle is to let the ore enter the tower mill through the feeding system, mix with the grinding media, and then make the grinding media generate high-speed vertical movement in the cylinder body through the stirring device. The ore is ground into fine powder through the action of friction and impact, and then discharged by the discharging system. However, when the existing ore tower mill processes a large quantity of ore grinding, there is only a single channel for grinding, resulting in low efficiency. Moreover, the grinding path is short during grinding, leading to insufficient thoroughness and the need for repeated grinding, which consumes a long time. In view of this, the utility model provides an ore tower mill device to solve the problems of low grinding efficiency and insufficient thoroughness of the existing tower mill.

Specific embodiments

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present utility model.

[0024] An ore tower grinding device, as Figures 1-6As shown in the figure, it includes a machine frame 1, a grinding cylinder 2 and a feeding cylinder 3. A screening component for screening materials is installed on the top surface of the machine frame 1. The grinding cylinder 2 is fixedly connected to the top surface of the screening component. The feeding cylinder 3 is communicated with the side of the grinding cylinder 2. A rotating rod 4 is rotatably connected to the center inside the grinding cylinder 2. A propeller blade 6 is fixedly connected to the rotating rod 4. A first motor 10 is installed on the top surface of the machine frame 1. The lower part of the rotating rod 4 penetrates through the screening component and is fixedly connected to the output shaft of the first motor 10. A grinding component for multi-channel grinding is arranged inside the grinding cylinder 2. A material guiding component for guiding the flow of materials is also arranged inside the grinding cylinder 2. During specific operation, the first motor 10 is started. Then, the output shaft of the first motor 10 drives the rotating rod 4 to rotate, and then drives the propeller blade 6 to rotate. Then, the materials enter the grinding cylinder 2 from the feeding cylinder 3. The rotating propeller blade 6 mixes and conveys the materials to the top of the grinding cylinder 2. When the top of the grinding cylinder 2 is covered with materials, the propeller blade 6 will continue to convey the materials to the top. Then, the materials are mutually extruded and move downward, and flow into the grinding components of different channels through the guidance of the material guiding component for grinding. The formed materials after grinding are screened out by the screening component, and thus the grinding of the ore is completed.

[0025] Further, the grinding assembly includes a mounting frame 703 fixedly connected to the lower part inside the grinding cylinder 2. Three partition plates 701 are fixedly connected to the top surface of the mounting frame 703. Grinding channels are formed between adjacent two partition plates 701 and between the outermost partition plate 701 and the inner side of the grinding cylinder 2. The grinding channels are divided into three channels from outside to inside. Grinding media 702 are arranged on the inner walls of the three grinding channels. The grinding media 702 are steel balls. The steel balls have good wear resistance and can maintain a long service life during long-term use. The material guiding assembly includes a spiral tube 801 arranged in the grinding channel. The spiral tube 801 is made of high manganese steel. High manganese steel has excellent wear resistance and impact resistance and can be applied to high-wear environments. The material guiding assembly further includes a second motor 803 installed on the top surface of the grinding cylinder 2. A rotating circular plate 802 is rotatably connected to the upper part inside the grinding cylinder 2. The output shaft of the second motor 803 is fixedly connected to the rotating circular plate 802. The bottom surface of the rotating circular plate 802 is fixedly connected to the upper part of the spiral tube 801. During specific operation, when the materials are squeezed against each other and move downward, the materials will move spirally downward in the grinding channel under the drainage of the spiral tube 801, thereby increasing the distance during material grinding, prolonging the contact time between the materials and the grinding media 702, experiencing more extrusion and friction, thus improving the grinding efficiency, making the materials be ground more fully, and prompting the material particles to become finer. When the propeller blades 6 no longer transport the materials to the top of the grinding cylinder 2, a large amount of materials still remain in the top of the grinding cylinder 2 and in the grinding channel. At this time, start the second motor 803. The output shaft of the second motor 803 drives the rotating circular plate 802 to rotate, and then the rotating circular plate 802 drives the spiral tube 801 to rotate, so as to continue grinding the remaining materials in the top of the grinding cylinder 2 and in the grinding channel, and thus can thoroughly clean the remaining materials in the top of the grinding cylinder 2 and in the grinding channel, effectively reducing the waste of materials.

[0026] Furthermore, the screening assembly includes a screening box 901 fixedly connected to the top surface of the frame 1. The top surface of the screening box 901 is fixedly connected to the grinding cylinder 2. A screen 902 is arranged inside the screening box 901. An outlet 9011 is arranged on one side of the screening box 901, and the bottom surface of the screening box 901 is inclined along the direction of the outlet 9011. The inclined bottom surface can utilize the gravity effect to make the screened material flow more smoothly towards the outlet, effectively improving the discharging efficiency of the material and reducing the blockage phenomenon. Guide rods 903 are fixedly connected to the four corners inside the screening box 901. The screen 902 is slidably connected to the guide rods 903. Elastic members 904 are wound around the guide rods 903. Two ends of the elastic members 904 are respectively fixedly connected to the screen 902 and the guide rods 903. Two chutes 9012 are symmetrically arranged on one side of the screening box 901. A connecting plate 905 is slidably connected inside the chutes 9012. The connecting plate 905 is fixedly connected to the screen 902. A third motor 911 is installed on the outer wall of the screening box 901. A cam 912 is fixedly connected to the output shaft of the third motor 911. The cam 912 is in contact with the connecting plate 905. The screening assembly further includes a baffle plate 906 fixedly connected to the four corners of the screen 902. During specific operation, the third motor 911 is started. Then, the output shaft of the third motor 911 drives the cam 912 to rotate. Then, the cam 912 is in contact with the connecting plate 905. Then, the cam 912 presses the connecting plate 905, causing the connecting plate 905 to perform a reciprocating up and down movement. Then, the screen 902 is driven to perform a reciprocating up and down movement, thereby realizing the vibration of the screen 902, filtering out relatively fine ores, and preventing the screen 902 from being blocked.
