how to find out ball mill rpm from motor and gear box output rpm Description

Motor Poles & RPM

RPM = Hz* (2 / poles) * 60. where. RPM = shaft rotation speed or revolutions per minute. Hz = frequency or cycles/sec. Poles = number of poles of your motor. So, for example, if you have a 4 pole motor on 60 Hz then RPM=60*(2/4)*60=1800 rpm. 60Hz is the most common frequency in the US. 50Hz is the most common frequency outside the US. Next Steps

Working out Revolutions Per Minute

Below are examples of the way to work out 'revolutions per minute', or RPM as it is usually called. In the example below the DRIVER gear is large than the DRIVEN gear. The general rule is - large to small gear means 'multiply' the velocity ratio by the rpm of the first gear. Divide 60 teeth by 30 teeth to find the velocity ratio. Multiply this ...

Cement mill - Wikipedia

Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker ...
