2020-5-30Speeds and feeds are the cutting variables used in every milling operation and vary for each tool based on cutter diameter operation material etc. Understanding the right speeds and feeds for your tool and operation before you start machining is critical
Read More2008-3-31The critical speed rpm is given by nC 42.29d where d is the internal diameter in metres. 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 allowing the use of different sies of grinding media. Large
Read MoreBall mills are usually operated at 75 of the critical speed. The critical speed is the speed where mathematically calculated the grinding media would centrifuge out. Mills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute which corresponds to a peripheral speed of 2.4 ms. A mill of this sie equipped with
