It is very important to master the operation process of the jet mill
Mastering the operation of the jet mill is very important to the jet mill itself, but many people are not very clear about the procedures of how to operate the jet mill safely, so we need to learn and understand.
All circuits and electrical components of the jet mill should be checked to see if they can work normally. Whether the machine has been grounded, so as to avoid the risk of electric shock when the cabinet is electrified. Whether the machine spindle is stuck, if any, it should be dealt with in time. During the operation of the machine, whether there is any abnormality, stop and check immediately if any. Check whether the blade is tight and whether the blade gap can meet the specified standards. Before using the pulverizer, check whether there are sundries or sundries in the working room, and remove them in time.
Feeding can be started only after the crusher is operating normally. Before shutting down the crusher, stop feeding. Wait until the machine is completely discharged before stopping. Feeding should be even, not excessive, so as not to increase the burden on the machine. During the operation of the jet mill, cleaning, maintenance, etc. cannot be carried out.
The main reasons for the high oil temperature of the lubrication system are: (1) Abnormal wear on the surface of the friction disc or the oil groove; (2) The quality of the lubricating oil does not meet the requirements; (3) The cooling system does not play a cooling role; (4) Lubricating oil The flow is low.
The hydraulic cone crusher oil temperature protection range of the crusher is 21-54℃, beyond this temperature range, the main motor is tripped and powered off under the control of the oil temperature gauge. In summer, the temperature is high. Due to the heavy load, the oil temperature of the two crushed cone crushers is relatively high. After driving for a period of time, the oil temperature will approach or exceed 54°C. In order to protect the equipment, only manual shutdown or automatic tripping is required. After each trip, the internal friction surface needs to be cooled to a certain temperature before driving again. This results in multiple stops in a shift, which seriously restricts the production capacity of cone crushers and affects The improvement of the system efficiency, therefore, the transformation of the cooling system is imperative.
Through analysis and transformation, it can be achieved: reducing frequent opening and stopping caused by excessive oil temperature, and improving the production capacity and system efficiency of the cone crusher.
Cause analysis Due to the high temperature in summer and heavy load of cone crushing, the oil temperature of the lubrication system is too high, and the critical value of the oil temperature gauge tripping and power failure that often reaches or exceeds 54 ℃. This causes the system to start and stop repeatedly in a shift, which severely restricts The normal production capacity of cone crusher affects the improvement of system efficiency.
