Ball mill is a common equipment for ore grinding. It has high grinding efficiency and good grinding effect. Limestone, dolomite and granite can be grinded by ball mill. In the process of using ball mill, our company should remind users to pay attention to the problem of slow start-up of ball mill, so how to solve the problem of slow start-up of ball mill?
If the starting speed of the ball mill equipment is relatively slow, it will seriously affect the productivity of the mill, the grinding body in the ball mill can not quickly enter the working state, and the raw materials to be grinded in a short time can not be effectively grinded. During this period, the operation power consumption of the ball mill will be 2-3 times higher than that of the normal, which is equal to the idle state, and for a long time, so on. If the start-up of the ball mill is not effectively improved, the grinding efficiency of the equipment will be worse than once. Ball mill, the main equipment of grinding powder for industrial buildings, can not guarantee the mill to meet the start-up requirement at the fastest speed during operation. This is why the material loaded in the mill can not be grinded and crushed accordingly. Here we will analyze the reasons for the difficulty in starting the ball mill.
First, before the ball mill starts running, we need to verify the load of raw materials in the mill. If the load of raw materials exceeds the power range of the mill, it will cause the start-up speed to run too slowly, which is equivalent to a start-up on the load state. In addition, the running-in situation of the ball mill's rotating shaft should be checked before the start-up to see the lubrication of the ball mill's rotating shaft. In fact, if the mill's rotating shaft is started without lubrication treatment, it is easy to cause slow start-up of the energy-saving ball mill, and in serious cases, it may also cause sudden failure of the mill.
