AI Technical Summary
During the grinding operation of a vertical mill, gaps exist between the grinding rollers and the grinding roller gate, leading to material and air leakage, which affects material utilization and grinding efficiency, and increases dust pollution.
It employs protective and rotating components, and achieves dynamic sealing through the connection structure between the bellows, grinding rod, and housing. Combined with the hydraulic cylinder to adjust the angle of the grinding roller to adapt to different working conditions, it ensures sealing performance and performs grinding through the flexible cooperation between the grinding wheel and the grinding disc.
It effectively prevents air leakage and material spillage inside the vertical mill, maintains good sealing performance, improves grinding efficiency and material utilization, and reduces dust pollution.
