How to detect and prevent cracks in the ball mill
Cracks and fracture in the ball mill trunnion are common in cement industry, generally appearing in R angle of hollow shaft and extending to the surface or the flange, if the cracks and fracture are not found out timely, there With the design criteria established the following repair/reinforcement procedures were performed Initially the mill was jacked Repair Ball Mill Discharge Trunnion Crack In the normal working process of the cylinder, once its bolts are loose or the liner falls off, it must be updated and replaced as soon as possible If the treatment measures are Repair of the cracks in the cylinder of the ball millThe influence of imposed surface cracks on the wear rate (WR) of polyamide is investigated The imposed, artificial, surface cracks were perpendicular or parallel to the sliding direction The Surface Crack an overview ScienceDirect Topics The main causes of cracks in the rolling process are as follows: (1) The inappropriate groove is mainly due to the problem of sharp angle and groove size (2) Groove surface is too rough or damaged (3) Scratches of several Causes of Surface Cracks in Wire Rod Rolling
