Ball mill is a heavy mechanical device necessary for grinding. Mill load parameters (MLP) relate to production economic indices and process safety. Mechanical signals of the ball mill are used to estimate MLP by domain experts. However, they can only estimate familiar mills effectively in certain time because of human limitation.
Abstract: The trait of the ball mill is chaotic in nature due its complex dynamics associated during grinding. Grinding in ball mill generates highintensity vibration and is too complex on account dependency of multiple variables. In this paper, the vibration signal is acquired using a low power ZigBee based three axes wireless
