Jan 01, 2015The vibration signal analysis for lab model sag mill is same as that of ball mill, but the frequency of operation of vibration signal and impact strengths are different [8]. Sag mill will require a higher value of g and BW of the sensor due to higher stiffness compared to that of ball mill (as the length of the mills is accounted).

Condition Monitoring of Ball Mill with HD Technologies

May 28, 2018In a ball mill, steel or stone balls are mixed with the ore and during rotation of the drum the ore is ground, by friction and compression, into a suitable fineness for the next step in the process. The main component of all mills is a rotating drum, turning with a suitable speed, gearbox, and motor.

Sep 15, 2020Ball mill is a grinding machine used in mineral processing, comprising of a rotating cylindrical shell filled with steel balls and the material to be ground. The ball mill is inevitably accompanied by vibration during operation since the main cause of this vibration is the tumbling of steel ball and material to be ground. This vibration may lead to resonance
