Compared with the ball mill system, the energy consumption of the vertical mill system can be reduced by 30% to 40%. The vertical grinding mill does not have the metal impact sound of the steel balls colliding with each other and the liner in the ball mill, so the noise is low, which is 20-25dB lower than that of the ball mill. In addition, the ...

The grinding action in a ball mill is achieved through two primary fragmentation mechanisms: attrition and the impact. Impaction happens when the grinding media (balls or hard pebbles) bump into each other and with the material being ground. This leads to the fragmentation of the substance into pieces of smaller size.
