The　high-pressure　micropowder　mill　is　developed　by　our　engineers　through　many　years'hard　work　on　the　basis　of　rich　experiences　of　industrial　mills. It　adopts　the　fineness　grading　technology　from　Germany　and　Japan　and　tackles　the　difficulty　in 　classifying　super-powders.　It　is　mainly　used　in　super-power　processing　with　more　than　500　kinds 　of　materials,such　as　feldspar,talcum,barite,marble,limestone,charcoal　blacks,　and　china　clay,　with　output　fineness　of　500　meshes(25um)to　2500　meshes(5um)and　the　minimal　fineness　of　3500　meshes(3.55um).
