Ball mill noise. ball mill level transmitter by sensing ball noise coal ball mill level measurement as the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate the risk of underloading or overloading the mill ball mill.

One of our ball mills keeps losing pressure on the high pressure pump. it will run fine when starting the mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. we have just grinded the journal and installed new white metal bearings. after startup this afternoon after about 1hrs the pumps low and high just lost pressure.

It seems to be a hardinge electric ear revisited. this device was patented by hardinge in the thirties to be used in a ball mill with fixed speed and an almost constant volumetric filling level, given the appropriate ball make up. the load remains approximately at the same place all the time, such that with only one sensor you cope all conditions.
