[0042] Specifically, the working process or working principle of a roller mill is as follows: when the existing product crushes the block material particles to a fineness of 5-0.045mm, a ball mill, a roller press, or a vertical roller mill is generally used. The product is added to the equipment for processing to achieve grinding of the product. When the initial particles of the product are large or small, the grinding distance during product processing must be adjusted accordingly, otherwise it will affect the grinding effect of the product. The existing grinding mill cannot adjust the grinding distance, which affects the use and reduces the grinding effect of the product. Therefore, this device is designed to solve this problem.
[0043] This device can adjust the distance between the grinding disc seat 15 and the grinding roller 20 to meet the needs of particles of different sizes, and is easy to use. The specific operation is to add the raw materials from the position of the feed bin 19 into the interior of the upper box body 18, and at the same time, drive the motor 1 and the reducer 9 to work. The reducer 9 will drive the connecting shaft 8 to rotate, and the connecting shaft 8 is connected to the main shaft 2 through a gear set. The gear set includes two bevel gears, one of which is installed at one end of the connecting shaft 8, and the other is installed at the lower end of the main shaft 2. The two bevel gears are meshed and connected, which can conveniently drive the main shaft 2 to rotate. When the main shaft 2 rotates, the roller seat body 7 can be driven to rotate, and the grinding equipment can be driven to rotate.
[0044] The grinding equipment includes a roller shaft 6 and a roller 20. The roller shaft 6 is stably mounted on the roller seat 7, and the roller 20 is sleeved on the roller shaft 6. The two are stably connected, so when the roller seat 7 rotates, the roller 20 can be driven to rotate inside the upper box 18, which is convenient for grinding the product.
[0045] During actual operation, the position of the grinding disc seat 15 can be adjusted according to the particle size of the product. When the grinding disc seat 15 moves upward, the distance between the grinding disc seat 15 and the grinding roller 20 will be shortened, which is suitable for grinding products with small particles. Conversely, when the grinding disc seat 15 moves downward, the distance between the grinding disc seat 15 and the grinding roller 20 will be increased, which is suitable for grinding products with large particles. By twisting the limit screw 403, the limit screw 403 is screwed out from the inside of the limit flange 402, and the grinding disc seat 15 can be controlled to move upward through the hydraulic cylinder 3, so as to shorten the distance between the grinding disc seat 15 and the grinding roller 20. When the limit screw 403 is screwed into the inside of the limit flange 402, the telescopic end of the hydraulic cylinder 3 is retracted, so that the grinding disc seat 15 can be controlled to move downward, and the distance between the grinding disc seat 15 and the grinding roller 20 can be expanded, so as to process products of different specifications.
[0046] When the product enters the upper box body 18, it will enter the position of the outer surface of the grinding disc seat 15, and when the roller seat body 7 rotates, it will drive the grinding roller 20 to rotate. The grinding roller 20 grinds the product on the grinding disc seat 15 to meet the needs of use.
[0047] While controlling the movement of the grinding disc seat 15, the device will also drive the height sensor 503 to move. The distance moved by the height sensor 503 will be displayed on the display, so that the working status can be grasped in time, and the real-time gap between the grinding disc and the grinding roller 20 can be observed, so that the operation status of the equipment can be controlled and adjusted in the first time to achieve the best state.
[0048] In order to improve the grinding effect on the product, this device adjusts the distance between the grinding roller 20 and the grinding disc seat 15, and ensures that the distance between each grinding roller 20 and the grinding disc seat 15 is consistent, so as to grind the product to meet the processing needs. In order to ensure the stable use of the grinding roller 20, a sphere 16 is installed at the upper end of the main shaft 2, and the sphere lower shell 10 and the sphere upper shell 14 on the outside of the main shaft 2 are connected together by fastening bolts, so that the roller seat body 7 can be stably installed on the main shaft 2, and the grinding roller 20 can be stably used, thereby improving the processing effect on the product.
