[0002] Grinding mills are widely used in industries such as mining, building materials, and chemicals, and grinding mill liners are a crucial component. During the manufacturing process of grinding mill liners, their surfaces are typically sanded and polished to achieve a smooth finish.

[0003] Traditional methods for surface treatment of mill liners often involve manual grinding, which is inefficient and makes it difficult to guarantee surface treatment quality. Existing mechanical polishing equipment is often unable to effectively polish the special shape of mill liners. During the polishing process, a certain amount of heat is generated, causing the local temperature of the liner to rise. Therefore, during the polishing process, it is necessary to wait for the mill liner to cool down before continuing the operation, which makes the polishing inefficient.

[0004] Therefore, it is necessary to propose a mill liner processing and polishing device. Utility Model Content

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Polishing mill liners is typically done to improve their surface smoothness and reduce material adhesion and wear during the grinding process. Here are some common mill liner polishing methods:

[0028] Mechanical polishing principle: Physical friction is applied to the surface of the lining plate using polishing equipment or tools to remove surface protrusions, burrs, and microscopic unevenness, achieving a certain degree of surface smoothness. Common tools: Grinding wheels, sandpaper, polishing wheels, etc., can be used. For example, a coarse grinding wheel is used for initial grinding, followed by a fine grinding wheel for fine grinding, and finally a polishing wheel for polishing. Advantages: Relatively simple operation, quickly improving the surface condition of the lining plate; suitable for lining plates with regular shapes and large areas. Disadvantages: May generate some heat, causing localized temperature increases in the lining plate, affecting its material properties; polishing is more difficult and less efficient for lining plates with high surface hardness.

[0029] Chemical polishing principle: This method utilizes a chemical reagent to react with the surface of the backing plate, dissolving tiny protrusions and achieving a polishing effect. Commonly used chemical reagents include acids, alkalis, and oxidizing agents. Different backing plate materials require different chemical reagents and formulations. For example, for metal backing plates, polishing solutions containing a certain proportion of nitric acid and phosphoric acid can be used. Advantages: It can achieve high surface quality and uniform polishing effect; it is suitable for backing plates of various complex shapes and can reach areas that are difficult to reach with mechanical polishing. Disadvantages: Chemical reagents are corrosive, requiring strict control of usage conditions; otherwise, it may cause excessive corrosion to the backing plate; the operation requires certain professional knowledge and skills, and attention must be paid to environmental protection and safety issues.

[0030] Electrochemical polishing principle: The substrate is placed in a specific electrolyte, acting as the anode. An electric current causes an electrochemical reaction on the substrate surface, dissolving uneven areas and achieving polishing. Commonly used electrolytes: Different electrolytes can be selected depending on the substrate material, such as sulfuric acid and chromic acid. Advantages: Excellent polishing effect, achieving a highly smooth surface; precise control over the polishing depth and range, suitable for substrates requiring high surface precision. Disadvantages: High equipment investment, complex operation, requiring specialized technicians; high cost of electrolyte treatment and recycling, and certain safety hazards.

[0031] Ultrasonic polishing principle: Utilizing the high-frequency energy generated by ultrasonic vibrations, particles on the surface of the lining plate undergo cavitation in a liquid medium, thereby removing surface dirt and micro-protrusions, achieving polishing. Common equipment: Ultrasonic polishing machine, equipped with corresponding polishing heads and abrasives. Advantages: Fast polishing speed and high efficiency, achieving good polishing results in a short time; suitable for lining plates of various materials, especially thin-walled and fragile lining plates. Disadvantages: Higher equipment price and maintenance costs; requires a high level of operator skill, necessitating mastery of appropriate polishing parameters.

[0032] However, mechanical polishing is commonly used when polishing mill liners. It is easy to maintain and has low cost. When using a polishing wheel, the mill liners need to be fixed. In existing devices, the mill liners are polished by hand on the polishing wheel. At the same time, a certain amount of heat is generated during the polishing process, which causes the local temperature of the liners to rise. Therefore, during the polishing process, it is necessary to wait for the mill liners to cool down before continuing the operation, which makes the polishing efficiency low.

[0033] Reference Figures 1-3As shown, a mill liner processing and polishing device includes a polishing platform 100. The upper surface of the polishing platform 100 has an installation groove 101. A construction mesh plate 102 is placed inside the installation groove 101. A polishing frame 200 is fixedly connected to the top of the polishing platform 100.

A polishing motor 303 is fixedly connected to the output shaft of the telescopic electric cylinder 302. A base box 500 is placed inside the polishing platform 100.

[0034] After placing the mill liner on the surface of the construction mesh plate 102, the electric telescopic rod 400 is activated, which drives the push plate 401 to move, thereby clamping and fixing the mill liner. Then, the polishing motor 303 is activated to polish the mill liner. The horizontal axis moving rail 300, the vertical axis moving rail 301 and the telescopic electric cylinder 302 can move the polishing motor 303, which facilitates polishing operations on different positions on the mill liner. During operation, the water pump 602 inputs water through the water pipe 601 into the nozzle 600 and sprays it onto the mill liner to cool it down.
