During the construction process, due to the inaccurate ordering of spare parts, the maintenance time was extended, and the construction was shared for six days. The steel ball in the mill does not fall, and the first end of the broken bolt corresponding to the broken end cap lining is removed, the burr of the mating surface of the nut and the cylinder is leveled, the connecting bolt is replaced and fastened, and the back end is replaced. Before the cover liner, a castable is placed between the liner and the gap between the cylinders. Ercang removes the broken bolt corresponding to the output rafter plate in the mill, and cuts off part of the slab skeleton corresponding to the broken bolt. The nut is between the cylinder and the 20mm thick steel plate. The steel plate has the same diameter as the discharge port. Large, steel plate and raft plate skeleton, lifting plate, respectively welded together, bolts through the raft, skeleton, cylinder to steel plate, rafter plate skeleton, lifting plate, cylinder fixed together. The broken bolt can be replaced by cutting a small piece of steel plate at the corresponding 20 mm thick steel plate at the broken bolt. The maximum length of the end cap liner bolt and the discharge tweezers bolt is M30×2×685. It is difficult to remove the bolt. Only the bolt can be cut and taken out, and some bolt threads are broken, so sufficient mechanical equipment must be prepared.
Special care was carried out during the post-repair operation on October 6, 2004, and detailed special care records were carried out to establish a regular inspection and irregular inspection system. During the repair operation, periodically check whether the hollow shaft flange and the barrel connecting bolt nut are loose. Regularly tighten the nut with the same force.
Pipe network layout can also save land. In the past, most of the production and living cycle network and sewage pipelines, cable trenches, etc., are buried directly underground. The pipeline spacing is more than 1.5m, and the total width is about 7-8m. If it is in the non-freezing area in southern China, it can be electricity. The pole type is erected from 1 to 1.5 m wide, which can save 5 to 6 m of land. According to the main production line of cement, it can save more than 0.5ha. It is also easy to maintain and overhaul. It is better to build together with the cable tray.
