Prediction of particle composition distribution after fragmentation of heterogeneous materials

摘要: Abstract A review of problems encountered in developing prediction models for composition distribution particles obtained by the breakage multiphase materials is presented. The needs to characterize texture image analysis, describe particle production similar methods, relate and texture, use integral geometry methods stochastic geometrical processes solve complex probability equations three dimensional space, are stressed. presentation made developed other researchers, which illustrates some their deficiencies. complete a model incorporates required elements. special case model, combining description based on Boolean with primary Poisson polyhedra grains, calibrated screen fractions extracted from ground ores, independence breakage, Applications data presented researchers give evidence its value especially predicting at sizes or coarser than grain sizes.
