Regarding the bar mill turning gear
Thread Content
At present, the single-unit test run of the rod mill has been completed; it is at zero load and stopped for an extended period. Is periodic turning of the shaft required? What are the consequences of not turning the shaft?
If steel rods are installed, regular turning of the shaft is necessary. Think about it – can it be good to be under stress in one place all the time?
Water needs to be added when turning the disk; an empty disk may cause misalignment of the rods
Previously, manual turning of the equipment was required; now, the equipment manufacturers provide jacks that can be used to lift the equipment when it isn’t in use for extended periods of time.
It is generally confirmed that the presence of water or slurry inside provides fluidity. In that case, it should be checked every four hours. If there is no water inside, water must be added until it overflows; if there is dry coal or dry coal slurry inside, water also needs to be added, and the auxiliary motor should be used in intermittent operation to rotate the shaft to prevent the rods from getting disordered. The purpose of turning the shaft is to check that the equipment is in good condition and ready for use, as well as to prevent shaft bending due to prolonged idling
Regular turning of the shaft is sufficient, usually once a week
Regularly perform gear turning to prevent the mill bearings from bending and deforming due to excessive weight
The coal grinder cylinder rotates 180°; it is not a random rotation； Additionally, for long-term parking, the vehicle can be lifted using a jack, in which case there is no need to turn the engine.
Prevent the mill bearings from bending and deforming due to excessive weight and constant partial loading
