Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a high-efficiency wear-resistant lining plate for a ball mill in a cement plant. Background Art

[0002] Ball mills are essential equipment for grinding raw materials and finished cement in cement plants. Ball mills pulverize materials through the interaction between steel balls and abrasive material within a rotating drum. They are typically used for fine grinding of minerals and other hard materials. The efficiency and durability of a ball mill directly impact a cement plant's production efficiency and product quality. Therefore, the design and material selection of each ball mill component, particularly the liner, are crucial.

[0003] However, traditional ball mill liners present several problems during actual use. First, the connection between the liner and the cylinder is not stable enough, which can easily cause the liner to loosen or fall off during operation, thus affecting the normal operation of the ball mill. Second, in the high-intensity, high-frequency working environment of the ball mill, the liner is susceptible to severe wear and vibration, which not only reduces the service life of the liner, but also increases the frequency and cost of maintenance and replacement. In addition, the existing liner's cushioning and shock absorption effects are not ideal, and it cannot effectively reduce the impact and vibration generated during the operation of the ball mill, which affects the ball mill's operating efficiency and equipment life. Therefore, we provide a high-efficiency, wear-resistant liner for cement plant ball mills. Utility Model Content

[0036] Working principle:

[0037] like Figure 1-4 As shown, the drum mechanism 1 consists of an outer drum 11, an inner drum 21, a sealing plate 12, and an inlet pipe 13. The outer drum 11 is fixed at one end by the sealing plate 12, and the other end is connected to the outlet pipe 35 via a docking mechanism 3. Material enters the drum through the inlet pipe 13 for grinding. The inner and outer drums 21 are fixedly connected by a docking frame 22, and a damping buffer 23 is provided to reduce vibration and abrasion generated during the grinding process. The docking mechanism 3 includes an outlet pipe 35, a second protective ring 33, a protective frame 32, and a protective plate 34. The outlet pipe 35 is connected to the end of the outer drum 11 away from the sealing plate 12 to ensure smooth discharge of the ground material. The second protective ring 33 is nested on the outer surface of the outlet pipe 35 and rotates within the protective frame 32 to provide protection and stability. Material enters the inner drum 21 through the inlet pipe 13. During ball mill operation, the drum mechanism 1 rotates, and the grinding media in the inner drum 21 impacts and grinds the material. The damping buffer 23 absorbs some of the impact energy, reducing the impact of vibration on the equipment. The ground material is discharged through outlet pipe 35. A second protective ring 33 and protective plate 34 protect outlet pipe 35 from excessive wear. A gear ring 31 is nested on the outer surface of outer cylinder 11 and connected to the ball mill drive system. It drives the roller mechanism 1 through rotating mechanism 2. This high-efficiency, wear-resistant liner, through its rational structural design and multi-layered protection mechanism, ensures the stability and wear resistance of the ball mill under high-intensity operating conditions. It reduces vibration, enhances wear resistance, and maintains high efficiency and stability during long-term operation, thereby improving the ball mill's operating efficiency and service life.
