The challenge is to measure it cement producers are required to measure and report to government agencies about the air that flows up the cement mill stack the value of airflow in m 3 hr can be back calculated using the mill diameter and media fill level to a velocity over the mill internals however the disadvantage of this method is that

So far the main method to measure the ball mill load are direct and indirect methods the direct method has been put forward in the international mineral processing congress at 1973 the direct method use pole to measure the height of ore pulp liquid level to get the load it cannot be popularized since the problems of pole damage

Study on the method for collecting vibration signals from mill shell based on measuring the fill level of ball mill by peng huang minping jia and binglin zhong cite bibtex full citation publisher hindawi limited year 2014 doi identifier 1011552014472315 oai identifier

Usually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level it is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration figure 2 shows that there is no linear relation between

Table of contentsimpact test ballinstrumented ball testsfactors affecting impact in grinding balls of many physical parameters critical to design of grinding processes impact of grinding media is among the most difficult to measure or predict yet impact of falling grinding balls pebbles or rods accomplishes the fine grinding essential to metallurgical recovery of most important minerals

Observation total height of ball mill 67 inch 558 ft height of ball feed material 54 inch 45 ft empty space 13 inch 108 ft percentage of fill level 5467100 8059 percentage of empty space 1941 fill level the load of the ball is usually a little more than half of the volume of the mill generally 23 volume of the

On the s width method small direct measurement differences cause big variations on the charge level estimatives and the trend of such errors is to increase in smaller diameter mills which is the case of the measured ball mill the mcp eliminates vague criterias adopted by people while measuring mill internally by common methods

Mill level measurement by noise level transmitter mill level measurement by noise level transmitter 503a which generate 420ma new method to measure the fill level of the ball mill i zhang studied t he fill level by measuring the power and bp neural network based r ecognition of level of coal in ball millj

New method to measure the fill level of the ball mill i theoretical analysis and dem simulation huang peng jia minping zhong binglin engineering

Fill level measurement for ball mills in contrast to all existing classical methods of ball mills fill level measurement smartfill is the only system which measures the sound directly where it occurs on the mill

The solution about the noise of ball mill 1acoustic enclosure soundproof hood use the acoustic enclosure to cover the whole ball mill and then add a sound absorbing device in the hood to eliminate the reverberation noise this method usually gains the noise reduction of 2545db a but it does not effectively isolate the ball mill
