On the premise of normal no-load test run, further check whether the process is reasonable and whether the auxiliary equipment and main equipment are normal through load test run at different stages. Through trial operation, all the equipment of the system can be run-in and adjusted under different loads. Ensure the long-term safe operation of system equipment. Comprises the mixed transportation of cement grinding and the transportation and warehousing of cement grinding. Including the transportation of raw materials such as clinker, gypsum and limestone. All equipment of cement grinding system should be carefully checked and adjusted before starting. This should not only be done in trial production, but also be strictly implemented as a system in future production. The lubrication of equipment plays a key role in ensuring the long-term stable operation of equipment. The amount of lubricating oil should meet the requirements of the equipment, that is, neither too much nor too little. Too much oil will lead to equipment heating; If there is too little oil, the equipment will be damaged due to lack of oil. On the other hand, it is necessary to regularly check, replenish and replace lubricating oil. The variety and label of the oil used should not be wrong, and it should be ensured that the oil does not contain water and impurities. The main inspection items are as follows:

Sundries in the equipment to prevent the equipment from being stuck or damaged during operation, causing unnecessary losses. After the internal inspection of the equipment is completed, all manhole doors and access doors should be strictly sealed to prevent air leakage, material leakage and oil leakage in the production process. Before starting the equipment, it is necessary to conduct a comprehensive inspection of the equipment, and dismantle the pull rod brakes at the entrance of each material quantitative feeder, and open them all to a suitable position to ensure the smooth flow of materials. For the inspection and adjustment of the heavy hammer tapping door, all the heavy hammer tapping doors should be adjusted according to the different loads of the mill, and the position of the heavy hammer should be adjusted appropriately.
