As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including quarry, aggregate, and different kinds of minerals.
through monitoring. Vibration data is processed to determine the condition of components in the drivetrain. One of the most powerful algorithmic tools for vibration analysis is the time synchronous average (TSA). Time synchronous average resamples the vibration data synchronously with a shaft, and is the basis of numerous gear and shaft condition

Time synchronous averaging of ball mill vibrations. INTRODUCTION. The pinion (Fig. 1) is driving the ring gear of the ball mill. The total power transmitted through the system is 4 MW. The plant had a record of pinion failures over approximately. 3 years. Significant production loss and secondary damage to foundations were recorded.
Mechanical Systems and Signal Processing (1989) 3(1 ), 99107 TECHNICAL NOTE TIME SYNCHRONOUS AVERAGING OF BALL MILL VIBRATIONS A. SZCZEPANIK Department of Mechanical Engineering, Monash University, Melbourne, Victoria 3168, Australia (Received February 1988, accepted April 1988) This note presents an investigation into the problems of ball mill pinions.
In this paper, the high frequency resonance technique, used for many years in the early detection of failure in rolling element bearings by vibration analysis, is combined with the technique of synchronous averaging, which has long been applied to vibration analysis of gears for the early detection of failure.
