 · CRITICAL SPEED OF THE BALL MILL Let a grinding ball of mass m is in motion in a mill of diameter D meters It is at a position making an angle a at the center (called the angle of repose). The force acting on the ball are described in the figure … The intensity of the ball mill noise is related to the diameter and speed of the ball mill, as well as the nature and blockiness of the material. Ball mill noise is basically steady-state noise, with a wide frequency band, and low, medium, and high-frequency components have high sound energy.

The solution about the noise of ball mill. 1.Acoustic enclosure (soundproof hood) Use the acoustic enclosure to cover the whole ball mill, and then add a sound absorbing device in the hood to eliminate the reverberation noise. This method usually gains the noise reduction of 25-45db (A), but it does not effectively isolate the ball mill ... The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

MILL CONTROL: BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a 0.4% grade copper ore from a nearby open pit mine. The unit operations consisting of crushing, grinding, and flotation process about 65,000 tons of ore per day in six overflow ball mills. Ball mill, as an indispensable grinding equipment in mineral processing, brings economic benefits to the separation plant.Ball mill is mainly used for grinding materials in the industrial production process. Because of the large volume and tonnage weight of the ball mill, the noise in the production process is relatively large, and the noise is generally above 95dB (A), which can exceed 1MdB ...

Introduction. The ball mill is indispensable grinding equipment in the ore beneficiation process.How to control the ball mill noise? Ball mill is mainly used for grinding materials in the industrial production process. Due to the large volume and heavy tonnage, the noise ( strong vibration and noise ) generated is usually above 95dB(A), which is serious affects the physical and mental health ...  · This application of electronic ear is used to control the mass of mineral that is possible to mill. It's usually used in cement industry. This control loop is inverted; so if the sound decressed, the feed of the mill has to decressed. Also this measure is used to generate an alarm that cut the feed of the mill to avoid excess of mineral.
