What is the reason why the sound of the cylinder suddenly becomes sharp when the mill is running?

The ore concentration is also known as the grinding concentration. It refers to the ratio of ore to water in the grinding machine barrel. It can be judged by the measurement result of the ore concentration of the grinding machine. Grinding concentration directly affects the fluidity of the slurry in the cylinder and the ability to transport the ore particles, and also affects the role of grinding media. Therefore, a grinding operator should be good at mastering the grinding concentration. Production practice has proved that the most suitable grinding concentration is between 60% and 83%. When coarse grinding, the grinding concentration is slightly larger. Generally, when the grinding machine is running, it is found that the sound inside the cylinder becomes sharp. If the time lasts longer, stop checking whether the lining is broken or damaged; check the ore. Whether the quantity is insufficient, it is generally found that this phenomenon is mainly due to these two reasons. Of course, sometimes we do not pay attention because in small repair or other wrench when iron is cast in the cylinder causes abnormal sound. If there is intermittent and dull shock inside the cylinder, it may be that a certain liner is detached; if the ball mill suddenly discharges the small steel ball and the nugget, it means that the internal lattice plate is damaged. Between 75% and 83%; during fine grinding, the grinding concentration can be lower, about 65% to 75%. The ore concentration of ore with different specific gravity should also be different. The concentration of grinding may be controlled to be higher than that of ore, and the concentration of grinding should be smaller when the proportion is small.
