We may have encountered high-pressure micro mills due to the operator's debugging or incorrect operation mode, resulting in a decrease in the output of the mill, poor discharge, coarse particle size, shortening the service life of the mill, some mills have been scrapped before reaching the service life required by the manual, in order to make this wrong effect be effectively solved, it is necessary to strictly follow the operating rules of the mill in daily work. First of all, the machine should be started, and a comprehensive inspection of the electrical equipment should be carried out before starting, and the connecting bolts should be checked to see if they are looseThe lubrication of each lubrication point, the operation of the transmission system, the operation of the protection equipment, the sensitivity of the electrical equipment and the contact of the carbon brush of the motor.
Then turn the machine around, check whether there are obstacles in the rotating parts of the machine and around it, and remove them. In the beginning, no one was allowed to stand nearby. After confirming that there is no problem with the mill, press the start button to start the motor and observe the change of its current. The three-ring and four-ring medium-speed grinding can not be started twice in a row, and the interval between each start is at least 5 minutes, if there are three starts, it should be checked with the cooperation of electricians and fitters. It cannot be started with other devices, and it must be staggered to start, otherwise it will cause a short circuit.
After the normal operation of the three-ring and four-ring medium-speed coal mills, it is necessary to operate in strict accordance with the procedures of water feeding, ore feeding, and steel balls, and it is strictly forbidden to overload, and the idling time shall not exceed 15 minutes, otherwise the lining plate will be damaged. During the operation, it is necessary to observe whether the hollow shaft and oil ring rotate, whether there is any problem with the temperature of the hollow shaft, and pay attention to the oil quantity and temperature of each lubrication part, and fill it regularly.
It is necessary to manage the mill in a scientific way to reduce unnecessary losses and unnecessary troubles. Turn the machine on and off frequently, clean the grinder frequently, and take care of every part of the machine!
