Analysis of Xingnong mineral processing equipment’s ball milling system after crushing hard ore materials

The ball mill is the key equipment for crushing the materials after they have been crushed. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal mineral processing, glass and ceramics and other production industries to dry or wet grind various ores and other grindable materials. The above is a vernacular explanation of the ball mill system of mineral processing equipment.
You may encounter various problems during the trial operation of the ball mill. The key is to find a good solution.
When the ball mill is running, there will be regular knocking sounds, and the noise is very loud. Some of the lining plate bolts were not tightened, and when the ball mill rotated, the lining plate knocked against the grinding cylinder of the ball mill. Determine the position of the ball mill lining plate based on the sound, find the loose bolts, and tighten them separately.
. Huge vibration occurs when the ball mill reducer is equipped with a ball mill
Reason 1: The axes of the balance shafts of the ball mill and the reducer are not in a straight line. The reason is that when the lining plate is installed on the mill, no secondary The anchor bolts after grouting or secondary grouting are not tightened properly. Use a winch to rotate the grinding cylinder, causing one end of the grinding cylinder to shift, and the two axes are not in a straight line, causing the reducer to drive the grinding mill and cause vibration. The processing method should be readjusted so that the axis of the ball mill and the axis of the reducer are on the same plane axis.
Reason 2: The large ball mill is large in size and heavy in weight, causing the foundation to sink and shift. Set up a monitoring settlement point next to the foundation for observation. If subsidence is found, make adjustments.
. The sound of abnormal operation of ball mill reducer should be uniform and smooth. The sound of normal operation of ball mill reducer should be uniform and smooth. If there is a slight knocking sound or hoarse friction sound in the gear, but there is no obvious change during operation, you can continue to observe, find out the cause, and stop the ball mill for processing. If the sound becomes louder and louder, stop the ball mill immediately for inspection.
After the ball mill motor with reducer is started, vibration occurs. The main reason is that the gap between the two wheels of the ball mill coupling is too small and cannot compensate for the movement of the ball mill coupling caused by the self-finding magnetic center when the motor is started. The alignment method of the shaft joint is incorrect, resulting in the connecting bolts of the non-centric ball mill coupling of the two shafts not being tightened symmetrically, and the degree of tightening force is different, and the outer ring of the ball mill bearing moves. The treatment method is to adjust the gap between the wheels according to the regulations to make the two axes concentric. Tighten the coupling bolts symmetrically with equal torque.
. Ball mill reducer bearing heats up
In addition to checking the temperature rise of the ball mill bearing, you should also check whether the exhaust hole of the reducer is blocked and clear the exhaust hole.
