Disadvantages of ball mill.T2312260000 mtw series heavy type european grinding.045 mm, the fineness is 0.038mm production capacity 3.5-45th processed materials limestone, calcite, barite, dolomite, potassium.
The main problems encountered in the use of raymond mill are excessive noise, equipment vibration, no powder discharged or products decrease, not qualified powder, and so on.Most skilled operators can detect potential failures in advance through sound and finished product status in order to prevent and control the issues as soon as possible.
Ball mill is formed by feeding part, discharging part, rotation part and driving part gear box, small transmission gearwheel, motor and electric control.The central hollow shaft is cast steel, the inner liner can be changed, the rotation big gearwheel is made by cast hobbling processing, and there are wearable liners with favorable anti-wear ability.
Analysis of noise and vibration during the operation of the ball mill 2 girth gear processing manufacturers give advice to customers who choose girth gears 1.
Reasons and solutions of grinding mill vibration noise.Grinding mill is very important powder production equipment.Recent years, manufacturers all did much work in how to reduce the noise of grinding mill, but with the limitation of various factors, the vibration and noise of grinding mill do not get solved fundamentally.

This amplitude modulation, caused by the multiplication of the higher frequency signal f h and the lower frequency modulation signal f l, results in a signal, at that is described by the standard equation.This expands to that is, the resultant frequency spectrum will contain peaks at frequencies f h, f h-f l and f h f lhz.The components f h-f l and f h f l are known as.
A vibration fft fast fourier transform spectrum is an incredibly useful tool for machinery vibration analysis.If a machinery problem exists, fft spectra provide information to help determine the source and cause of the problem and, with trending, how long until the pr oblem.
The mill runs smoothly, and the gear transmission has no abnormal noise.There is no looseness of the ball mill lining and various transmission parts.The operation of each department meets the maintenance requirements.After the ball mill is idling for a specified time, you can stop the ball mill, carefully check all working parts.
Gear noise is a page to learn causes and solutions of various types of noises gears make.This page is a part of khks introduction to gears.Tel 81 48 254 1744.
At higher speeds the noise level decreases significantly and so does the vibration.The amplitude of vibration beyond the critical speed is almost half compared to the mill vibration at 50 critical speed.Download download full-size image fig.Variation in the intensity of vibration with mill speed ball load 140 kg, clay powder 15 kg.
