对φ3.2m×3.1m格子型球磨机进料部结构及其在使用中存在的问题进行了详尽的分析,对进料部进料衬套结构与紧固方式、联合给矿器结构和进料端盖保护方式提出了有效的改进措施。实践证明,改进后的进料衬套紧固牢固,安装方便,有效地减少了联接螺栓松动、撸丝甚至螺钉断裂情况,联合给矿器的寿命得到了显著提高,进料端盖得到了有效保护。
The structure of feed section of φ3.2m × 3.1m grid ball mill and the problems existing in its use are analyzed in detail. The influences of feed bushing structure and fastening method of feed department, End cover protection proposed effective improvements. Practice has proved that the improved feed bushing is tightly fastened and convenient to install, which effectively reduces the looseness of the connecting bolts, the reeling or even the screw fracture, and increases the service life of the coal feeder in combination with the feeding end cap effectively protection.
