  • Factors Influencing The Grinding Efficiency Mill

    Even in a Mixer Mill, which generally uses less grinding media and therefore creates less friction than a planetary mill, temperatures exceeding 100 C are not unusual. When using spherical media in a ball mill, the only way to reduce friction is to reduce the number of pieces of media however, this in turn reduces the efficiency of grinding.Traditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling. However by far the most important factor for fine grinding is media size and therefore the breakage rate. Small media has a larger surface area which translates to better transfer of energy.

  • Cryomill The Perfect Mill For Cryogenic Grinding Retsch

    The impact classifier mill ICM is used for fine and finest grinding of brittle materials. During impact grinding, the grinding tools throw the feed material into the liner and crush it. Following this, the integrated classifier separates the material. The grinding fineness can be set there flexibly using the classifier’s rotary speed.Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 m.
