The use of the rod mill needs to experience a start-up process, and we cannot ignore the entire process. Although this operation seems to be simple, if the start mode is not correct, it will affect the normal use of the device, which will introduce it in the following introduction. Steps:
1. Before the start, it should be in contact with the production part, which is related to the work of the rod mill grinding unit. Electric's inspection of whether the insulation of the drive motor is good, whether the exciting control cabinet test is allowed, and the control device is activated when the control device does not fail. You can press the automatic start motor by the start button; the manual starter start the motor, press the start button, the motor starts to rotate, press the run button when the motor speed reaches the rated speed.
2, start the secondary sand pump and start the secondary ball mill, then start a sand pump and a roll mill, open the water valve to a mill and mud water supply, mill idle 1-2 minutes, standby group After normal operation, the feeding device can be activated, and the amount of feed is activated, and the feed is stabilized. Note that the front and rear end caps and the cylinder have leaks, and adjust the working conditions of the grinder according to the change of the ore.
3, the liquid level in the rod mill should be high, and the effect is to make the pump can be forth, while the air in the slurry has sufficient time to precipitate; observe the production of the cyclone , Normal production of a cyclone is marked as an umbrella shape, and a suitable umbrella angle is 20 ° -30 °. If the angle is greater than the angle, the deposit concentration is low and the fine particle content is high, and the grading efficiency is low. At an angle, the concentration of the gravel is high and the coarse score in the overflow is high, and the grading efficiency is also low. Adjust the amount of water added to the slurry tank to control the feed concentration of the cyclone separator to make the cyclone separator work well.
Note that the start-up mode will affect the rod mill. When starting, it should also observe whether the equipment has no abnormality, and cannot ignore its check because the equipment has always been ignored. At the same time, when starting, please keep the equipment in a well ventilated environment, while improving efficiency, it can also effectively reduce the device blockage.
