Energy and Cost Comparisons of HPGR based Circuits

Up until now tumbling mills such as AG/SAG mills and ball mills have had a dominant bearing on the design and economics of comminution circuits However it is commonly agreed that the majority of employed comminution processes are energy intensive and energy inefficient accounting for up to 80 of overall process plant energy consumption and having an efficiency of as low as 1

What are the characteristics of the ball mill

Energy Hogs used in the comminution of ores See below figure These heavy monsters work by throwing a large charge of balls over and against the ore to grind it to a

Milling Machine Methods of Milling

28 06 2009  Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed the overall removal is quite brisk

typical ball mills

A ball mill with a breaker plate and a similarly sized typical ball mill without a breaker plate were studied in order to determine if the breaker plate can improve mill grinding efficiency At hypocritical frequencies of rotation it was found that the ball mill with the breaker plate grinds more efficiently and especially so for particles larger than 1 mm
