Comminution processes are one of the most common for processing energy materials, e.g. coal, biomass, and post-recycling elements. The hitherto unsolved problem is high consumption machines lack precise descriptions phenomenon comminution in terms relationship between design features mills properties comminuted materials. dynamic development simulation techniques based on advanced models method...

in this study, calcareous nannofossils at the boundary between tirgan and sarcheshmeh formations at taherabad and mozduran sections have been studied. these sections are located in the eastern kopet-dagh basin. 22 nannoplankton species of 14 genera in taherabad section and 20 species of 14 genera in mozduran section were identified. according to the first occurrence of index species and fossil ...

We report our experience with carbon-fibre reinforced plastic (CFRP) plates in the management of 19 problem fractures complicated by either infection, nonunion, comminution or contamination. The combination offers secure fixation without inhibition of callus formation.

dability of limestone in their mixtures. This behavior may be attributed to the Representative samples limestone, ilmenite, and quartz, were dry batch ground separately binary mixtures – ilmenite limestone-quartz different compositions ball mill. The study aimed investigate effect mixture composition on mill product characteristics as reflected each two components. results indicated that quartz...

The comminution at the grain size level for liberating valuable minerals usually requires highest size-specific energy. Therefore, a full understanding of process this is essential. Models based on Discrete Element Method (DEM) can become helpful tool purpose. One major concern, however, missing representativeness mineral microstructures in simulations. In study, method to overcome limitation p...
