Vibrating mills are a type of grinding mill that uses a mechanical vibration to generate highfrequency oscillations and produce a fine grind in a short amount of time. Vibrating mills have several advantages over traditional grinding mills, including higher milling efficiency, reduced noise and vibration, and lower energy consumption.

Abstract The grinding of material in a vibrational mill is considered. Grinding is regarded as a random process consisting of a series of uniform events. The process is assumed to be steady, simple, and ordinary. We interpret grinding in a vibrational mill as a random Markov process. The calculation is based on the Kolmogorov equation. The motion of the grinding bodies in the mill is assumed ...
