Product fineness during grinding in stirred media mills is mainly influenced by the specific energy input, the stress energy transferred by the colliding grinding media and the stress frequency. The stress energy from grinding media collisions is heterogeneously distributed in stirred media mills. Herein, in order to characterize the stress energy distribution and the local grinding media ...

WhatsApp: +86 18203695377Natural lignite from South Moravia was tested for the sorption of fluoride anion in concentration range from 5·10−5 to 8·10−4 mol/l. The lignite removes majority of fluorides and only about 13% of sorption is reversible upon leaching in pure water. Sorption data can be fitted by both Freundlich and Langmuir equations and both isotherms indicate presence of two principal sorption sites or ...
