Roller on a race.The second missing element was a comprehensive life theory that would fit the observations of palmgren.Palmgren, as will be discussed, distrusted hertz theory 12 and depended on a load-life relation for ball and roller bearings 11.In 1930, v.Thomas and h.Hoersch 13 at the university of illinois, urbana,.Get Price
Type of mill is much shorter than that in tube ball mill therefore, the crushing process and mixing process became more harmonized and this contributes to quality control.3 the installation space is smaller and this leads to lower noise level.4 this type of mill can crush materials which are too large to be fed into the tube ball mill.Get Price
