subject: To Achieve Safe Production Is Possible [print this page] Ball mill installation quality, ensure the normal work of ball mill is the key. Various types of ball mill installation method and sequence of essentially the same. To ensure that the ball can smoothly and reduce the harm to the structures, it must be installed in its weight 2.5 ~ 3 times of the reinforced concrete foundation. The foundation should play in solid soil, and plant foundation must have at least 40 ~ 50 mm distance.
Installation of ball mill, first of all should be installed in the main bearing. In order to avoid aggravating the hollow shaft shoulder and the bearing liner wear, two main bearing base plate of the elevation difference, in every meters length should not exceed 0.25 mm. Secondly, the installation of ball mill cylinder body, can be prefabricated entire simplified Department directly, also can be divided into several parts and installation, and shall check and adjustment of shaft neck and ball mill center line, the concentric errors must be guaranteed in each meter length should be less than 0.25 mm. The final installation of transmission of the parts.
In ball mill installation process, according to product technical standards for measurement and adjustment of. Check the gear radial swing and small gears meshing performance; and the small gear reducer concentric; and a motor and a speed reducer concentric. When all the installation conforms to requirements, can the foundation bolt and spindle bearing bottom plate final irrigation. To make the ball mill operation rate is high, the grinding effect is good, must strictly abide by the code for operation and maintenance. In the roller ball grinder starting before, should check all the connecting bolts are tightened; gear coupling and so on, the key and a mine feeder of the spoon head clamping condition.
Check ball mill tank and reducer oil is sufficient, the lubricating apparatus and instruments have no problem, whether the pipe flow. Check ball mill and classifier around without operation of the debris, and then use the crane wheel rotary ball mill for a week, loose tube ball charge and ore, and check ring and pinion meshing condition, there is no abnormal noise. Starting order, start energy saving ball mill lubrication pump, when the pressure reaches 1.5 ~ 2 kg / cm 2, was allowed to start mill, then start classifier. When everything is running normally, can begin to mine.
Ball mill in operation process, always pay attention to the bearing temperature, not more than 50 to 65 degrees C. Always pay attention to the motor, voltage, current, temperature, sound etc.. Always pay attention to lubrication system, oil in the oil tank shall not exceed 35 to 40 DEG C, to the tubing pressure should be maintained at 1.5 ~ 2 kg / cm 2. Check the size of the gear, the main bearing, classifier reducer transmission parts of lubrication, and watch the ball before and after the end caps, simplified, discharging box, the classifier overflow groove and sand return slot is blocked and sand leakage. Always pay attention to the change of ore properties, and to take appropriate measures timely.
Stop the ball mill, to stop feeder, to be simplified in ore after processing, and ball mill motor, the last stop of oil pump. With the help of the lifting device is proposed the spiral classifier sand surface, then stop the spiral classifier.
As the professional manufacturer of complete sets of mining machinery, such as Rotary dryer,Vibrating screen,VSI sand maker, Henan Hongxing is always doing the best in products and service.
