[0030] It should be noted that this utility model is an adjustable grinding disc for a lime powder grinder. Based on the required fineness of the lime powder, the cylinder 7 in the adjusting assembly 3 is activated. The cylinder 7, acting as a power source, drives the adjusting plate 8 to move laterally along the upper plane of the grinding box 2 via the linear displacement of the piston rod, forming a closed-loop adjusting link. The rigid connection between the adjusting plate 8 and the grinding motor 9 transmits the driving torque to the drive shaft 12, thereby driving the grinding roller 10 to achieve gap adjustment. By changing the relative distance between the grinding roller 10 and the bottom of the inner cavity of the grinding box 2, stepless control of the grinding particle size is achieved. During this process, the sliding sealing plate 14 and the sliding groove 6 form a dynamic seal, which can move synchronously with the adjusting plate 8 and maintain the airtight state of the upper part of the grinding box 2, preventing dust leakage. The torque output by the grinding motor 9 is transmitted through the drive shaft 12. 2. The material is transferred to the grinding roller 10, which achieves the rated speed. The grinding teeth 11 on the outer surface of the grinding roller 10 generate axial thrust through the 30° helix angle of the teeth, which guides the lime raw material into the grinding zone, realizing the shear-extrusion composite grinding effect. The sealing cover 15 and the through groove cavity 5 form a static sealing structure, which, together with the dynamic sealing of the sliding sealing plate 14, forms a double barrier to effectively suppress dust diffusion and avoid environmental pollution. The ground lime powder is guided by gravity through the guide plate and enters the discharge pipe along the discharge chute, forming a stable material flow channel. The box door 16 can be opened and closed from 0 to 180° through the hinge structure, providing an operating channel for cleaning the inner cavity. If it is necessary to clean or repair the inner cavity of the grinding box 2, the box door 16 can be opened through the handle on the inside of the front of the box door 16.
