For ultrafine limestone powder grinding mill , there are many unexpected situations encountered in production. In some cases, it is necessary to choose emergency shutdown, otherwise, it will cause great damage to the equipment. Here is to introduce the situations that require emergency shutdown. which and how to deal with them.
Situation 1: If the load of the main motor of the ultrafine limestone powder grinding mill, or the motor load of auxiliary equipment such as grading equipment and hoists exceeds the rated current value, and there is no obvious reduction by reducing or stopping the feeding process, then an emergency shutdown is required deal with.
Situation 2: When the temperature of the ultrafine limestone powder grinding mill main motor or auxiliary motor exceeds the specified value, or the motor burns out, and the temperature of the main bearing and transmission device bearing of the limestone powder grinding mill exceeds the specified value, an emergency shutdown is required to prevent hidden dangers in production safety.
Situation 3: The grinding head bin of the limestone mill is broken or the feeder is stuck, and the supply cannot be resumed in a short time. The automatic feeding control system failure of the equipment cannot be repaired in time, and the raw material is full, and there is no receiving capacity. , emergency shutdown is required for processing.
Situation 4: During the production process of the ultrafine limestone powder grinding mill, the meshing sound of the large and small gears of the edge drive is abnormal, there is a large vibration, and the abnormal sound or vibration of the reducer is abnormal, and it needs to be stopped for emergency treatment to reduce Security risks.
Situation 5: The bolts of the large and small bearings and bearing caps are seriously loose, the lubricating oil ring does not turn and the pulling is ineffective; or the oil pump fails, the oil pipe is blocked, and the lubrication system fails. In these cases, emergency shutdown is required. Check the specific reasons for these problems in the ultrafine limestone powder grinding mill, and then deal with them.
Situation 6: When the retaining ring, grinding door, and hollow shaft fixing bolts of the ultrafine limestone powder grinding mill are broken or fall off, or the lining plate is dropped, or the compartment plate is damaged, the damage of the parts makes the production of the equipment unable to proceed smoothly. At this time, An emergency shutdown is required for processing.
Situation 7: When the ultrafine limestone powder grinding mill has a sharp drop in the water pressure entering the mill (wet mill), the cooling water is blocked; the auxiliary equipment has a mechanical failure; the dust collection equipment fails to ventilate and collect dust. emergency shutdown.
