Reading & Lecture. In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill.
ball mill grinding calculation kw and rpm. Ball mill kw readings . Ball mill kw readings N IV 44X5800 255200W 2552KW When the ball mill is in normal the motor current is 40A the voltage is 6000 volt So the ball mill normal power is 240KW The power is increased by 63 when the raw material was fed and the grinding media charging kept.
speed of ball mill reading. Ball mills have been successfully run at speeds between 60 and 90 percent of critical speed but most mills operate at speeds between 65 and 79 percent of critical speed Rod mills speed should be limited to a maximum of 70 of critical speed and preferably should be in the 60 to 68 percent
Mill power 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.
Ball mills are a low-speed application typical rotational speed is 10-20 rpm, where bearing damage can be challenging to detect.Condition monitoring of the ball mill began in december 2016 and right from the start, the readings indicated potential …
