Increase Coarse Aggregate Crusher

Jan 01 2019 The coarse aggregates obtained by different crushing mechanisms jaw and impact crushers show very similar characteristics in terms of binder content assessed by acid leaching 27.5 and 26.6 wt. water absorption 8.76 and 9.75 wt. and porosity 18.6 and 20.2 vol.. Thus it is not possible to conclude that any of these mechanisms are more efficient in removing the cement paste attached to original aggregate
