Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement processing technology, and in particular to a lightweight, wear-resistant cement mill activation liner structure. Background Technology
[0002] Tube mills are a crucial fine grinding device in modern industry and one of the most common and important pieces of equipment in grinding systems. Their working principle is as follows: when the tube mill cylinder rotates, the grinding media inside the cylinder are lifted to a certain height under the combined action of centrifugal force and friction. Some of the grinding media leave the circular track and fall freely along a parabolic trajectory, generating impact force that crushes the material. The remaining grinding media undergo a cascading motion, and the relative sliding between the grinding media further grinds the material. To achieve the purpose of grinding materials, it is necessary to improve both the crushing and grinding efficiency of the grinding media and the probability of grinding the material, i.e., to ensure the residence time of the material inside the cylinder. Especially in open-circuit grinding systems, to increase the probability of grinding the material, an activation device is usually installed in the fine grinding chamber of the tube mill to extend the residence time of the material inside the cylinder.
[0003] The existing application publication number CN219723095U discloses an anti-clogging activated liner for a mill, including a top plate and side plates arranged perpendicularly to each other. The side plates have a material channel opening on the surface away from the top plate. A screen plate with a thickness of 8-10 mm is fixedly installed at the material channel opening. The thickness of the screen plate is less than that of the side plates, and the surface of the screen plate has a number of screen holes evenly distributed. The addition of a screen plate to the traditional activated liner extends the grinding time of the material, allowing the material to be fully ground before being discharged from the screen holes to the other side. Because the thickness of the screen plate is less than that of the side plates, the fine powder material can pass through the screen plate quickly, avoiding screen hole clogging and grinding problems, thereby improving production quality and efficiency.
[0004] However, this solution still has shortcomings: 1. Cleaning and maintenance challenges: After prolonged use, the screen plate needs to be cleaned, and the entire liner plate needs to be removed for cleaning. The process is too cumbersome, resulting in low cleaning efficiency and difficulty in meeting the requirements of continuous production; 2. Limitations in flow regulation: The existing side plate design is fixed and cannot flexibly adjust the length according to actual production needs, thus failing to effectively control the material flow and limiting the application of the equipment in different production demand scenarios.
[0005] Therefore, it is necessary to provide a lightweight, wear-resistant cement mill activation liner structure to solve the above-mentioned technical problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lightweight, wear-resistant cement mill activation liner structure.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight wear-resistant cement mill activation liner structure, comprising a top plate and side plates, wherein the side plates include a first side plate, a second side plate and a third side plate, the first side plate and the top plate are arranged perpendicularly to each other, the second side plate is detachably connected to the first side plate and the third side plate respectively, a process hole is provided in the center of the first side plate, a first sieve plate is provided in the center of the second side plate, a second sieve plate is provided in the center of the third side plate, and an installation hole is provided on the top plate.
[0008] Preferably, the first side plate has a first side plate mounting groove on the side away from the top plate, and the second side plate has a second side plate mounting seat on the side close to the first side plate. The first side plate mounting groove and the second side plate mounting seat cooperate with each other. The second side plate has a second side plate mounting groove on the side away from the second side plate mounting seat, and the third side plate has a third side plate mounting seat on the side close to the second side plate. The third side plate mounting seat cooperates with the second side plate mounting groove.
[0009] Preferably, the front and rear ends of the first side plate, the second side plate, and the third side plate are all inclined surfaces, the width of the connection between the second side plate and the first side plate and the third side plate is equal, and the slope of the inclined surfaces at the front and rear ends of the first side plate, the second side plate, and the third side plate is the same.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] In this invention, the detachable connection facilitates subsequent cleaning, avoiding the need for complete disassembly and replacement; only individual cleaning and replacement are required, resulting in higher efficiency. The segmented design allows for extending the length of the side plates according to actual needs, thereby controlling the material flow and meeting different production requirements. The slopes of the first, second, and third side plates are all consistent, ensuring that the sides of the side plates maintain a smooth line and making cement conveying smoother.
