Oct 19, 2019#0183;#32;Ball mills are extensively used in the size reduction process of different ores and minerals. The fill level inside a ball mill is a crucial parameter which needs to be monitored regularly for optimal operation of the ball mill. In this paper, a vibration monitoringbased method is proposed and tested for estimating the fill level inside a laboratoryscale ball mill.
Condition monitoring and fault diagnosis of ball mill gear . Ball mill is a typical representative of mineral processing equipment in mining machinery This paper was concerned with the deterioration process of monitoring of gear, including the change of vibration and the spectrum characteristics The common failure causes of gear and the methods of monitoring and diagnosis are given, which is
Operational Experience from the United States'' First Vertical Mill vibration mm/s Grinding aid % Blaine PSD from the vertical mill may not exactly match that of the ball mill
#0183;#32;From SN ratio for time response amplitude of vibration, it can be concluded that the best combination for the optimum value of time response amplitude of vibration are (Ball dia. = 5 mm, Speed = 5000, DOC = and feed = 1200), for Surface Finish the optimum values are (Ball dia. = 5 mm, Speed = 6000, DOC = and feed = 1500), for Material Removal Rate the optimum values are (Ball dia. =
Being a Ball Mill maintenance services company part of our role is to inspect the Gears. Pinion and Girth Gears may appear to be robust pieces of the machine however without careful monitoring of mesh alignment and lubrication systems, these expensive items quickly degrade and can ultimately fail in spectacular fashion.

Image 3. A principal overview of the ball mill. 4 System setup. Measuring equipment. Besides the gearbox, the electric motor and the support bearings of the girth wheel are equipped with shock pulse and vibration transducers. Other applications monitored are a fan and a wind sifter. In total, sixteen shock pulse transducers and eight vibration transducers are connected to an Intellinova standard system.
Analysis of Vibration Signal of Ball Mill. 112720; 39 Views; icon 0; Gold ore dressing equipment the ball mill is the core production equipment in grinding. On the one hand, its working status determines the quantity and quality of raw materials in the subsequent production process.
The mill rotor bearings, which are mounted in the steel housing, are two (2) cylindrical roller bearings, NU 316 ECM/C3, and one (1) grooved ball bearing, SKF 6316 C3. The bearings have failed several times over a period of two (2) years. Before this time, the mill had no recorded bearing failures
The 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).
