When a Vietnamese cement company was replacing the reducer units used in the roller mills associated with its raw material grinding processes, it was found that the shaft journals of both the moving and stationary rollers were worn and damaged to varying degrees. Although the wear is minor, the use of a tensioning sleeve assembly combined with high operating torque means that the current condition can no longer ensure the proper operation of the equipment. Due to the large size of the equipment and the inadequate technical maintenance capabilities in Vietnam, the only option is to disassemble the equipment and send it back to the home country for repair. The long time required for disassembly and the high costs associated with it severely hinder the continuous production of enterprises. At the recommendation of industry professionals, Sinoma International Nanjing Office tasked Sinoma Equipment (Zibo) Company with contacting our company to address this issue, and technical evaluations were conducted regarding solutions for fixing such problems. Ultimately, at the end of April 2014, our company’s technical staff went to the site to guide their team in applying the FosilBlue technology for on-site repair of the equipment. Through the joint efforts of personnel from both sides, the equipment was repaired fully in just 3 days, preventing the company from suffering significant economic losses due to prolonged downtime.
