Chinalco Henan Branch's alumina plant raw material workshop went all out to organize the mill to drive

At 11:30 on October 17th, Chinalco Henan Branch's raw material workshop of the alumina plant passed emergency repairs for two days. The No. 5 lattice mill that had been suspended for six months was successfully opened, and the trial run with strips was successful and put into normal production.

According to the work plan of the alumina plant “Qianqian Q4, cost reduction of RMB 50”, in order to ensure the stable supply of the six groups of pipelined production slurry, the raw material workshop needs to restore the No. 4 and No. 5 lattice grinding capacity that has been shut down for nearly six months. On the afternoon of October 14th, after receiving instructions from the mill to resume driving, the raw material workshop convened a mobilization meeting for the grinding machine overnight to formulate a detailed plan for the belt corridor, lattice mill restoration drive plan and emergency repair of its equipment, and strived for the 17th. Resume production and produce qualified pipeline slurry.

In order to ensure that the grid grinding was started on schedule, all employees of the workshop voluntarily gave up their rest and went all out to work on restoring the equipment to repair the equipment. On the 15th, the staff of the workshop and the production backbone launched a 7-transmission motor belt conveyor, 6 belts and tugs, 4 and 5 grid grinders, 2 mixers, 2 slurry pumps, and 2 buffers. A thorough investigation was conducted and emergency measures were taken to solve problems such as the failure of the oil pump of the mill and the elimination of equipment obstacles. On the 16th, the workshop staff divided the two roads to conduct a surprise battle against the two “hard bones” that restricted the driving of the mill.

At 10 a.m. on the 17th, all the belts of the belt corridor opened normally, and the material outlets of the smashing ore yard were dug to fully transport materials to the silo. At 11:30, the No. 5 lattice mill successfully took the material to drive successfully.
