Ball mill  Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

Mill (grinding)  Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The reason and control method of ball mill noise
The ball mill can reduce the noise of the ball mill below the allowable standard. (3) rubber liner is used instead of manganese steel liner in the ball mill, the noise level can be reduced by 9dB(A), and the frequency spectrum characteristics of the ball mill also change from high frequency to low frequency.
