Noise Control of Ball Mill
Noise has always been one of the environmental and health hazards caused by the use of industrial equipment. As one of the major equipment of industrial production, noise control of ball mill has become an important indicator of industrial production quality. In this paper, the noise control of ball mill is discussed in detail.
The ball mill is a commonly used machine in mining, metallurgy, chemical, pharmaceutical, construction and other industries. It is an important equipment for the grinding of raw materials. However, due to the structure, complex process and high noise, the operating environment of the ball mill is bad, and the noise is relatively high. Generally, it should not exceed 85dB (A). Excessive noise will cause a certain degree of damage to the physical and mental health of the operator, so noise control has become a top priority. Therefore, it is necessary to scientifically and reasonably control the noise of the ball mill.
At present, there are mainly two ways to control the noise of the ball mill, including: intrinsic noise reduction and external noise reduction. Intrinsic noise reduction means adopting some measures to reduce the noise source strength in the device itself, such as increasing the damping system of the machine. External noise reduction means setting up corresponding sound insulation measures around the ball mill to reduce the surrounding environment noise.
The most effective way to reduce the noise of the ball mill is to enclose the entire machine with a protective cover. The protective cover should use the material with good sound insulating effect. At the same time, pay attention to the tightness of the joint of the overall protective cover. The installation environment of the ball mill should also be reasonably selected. Choose a spacious and ventilated environment with complete supporting systems to avoid the reverberation effect of sound waves.
At the same time, reasonable maintenance and operation of the ball mill can also reduce the noise generated by it. During the working period, you should always check whether the motor bearing or reducer bearing is working normally. Once the gear is worn or damaged, it should be repaired or replaced in time. Otherwise, it is easy to cause abnormal noise and vibration, which is not conducive to noise reduction.
In summary, the ball mill noise control is a complicated and uncertain process, in which the selection of control measures must take into account the characteristics of the process operation. However, with reasonable design and reasonable maintenance and operation, it is possible to effectively reduce the noise of the ball mill.
