Asphalt Mixture Fineness Mill Processed Ore Packing Requirements

 Asphalt mixture of limestone or slag must adopt strong magmatic rocks mafic rocks hydrophobic aggregates obtained by ground slag, clay impurities in the original stone should be Ex . When using fly ash as filler , the amount shall not exceed 50% of the total filler , LOI should be less than 12% fly ash , slag mixed with the plasticity index should be less than 4%, but the highway , a asphalt surface roads should not be used to make fly ash filler .

 Fly commonly used as an ash fineness fineness: refers to 45μm square mesh sieve margin of not more than 12% , which is the powder industry was often said 45μm by 88% (45μm equivalent to 325 mesh ) . Two ash fineness: 45μm square hole sieve margin requirement is not more than 25%. Three fly ash fineness: 45μm square hole sieve margin requirement is not more than 45%. For fine - original fly ash , the - original fly ash and coarse - original fly ash mortar , due to the use of fine - surface area greater than the original fly ash , ash has greater activity, mortar specimens various age compressive strength does not meet or exceed the strength of the fly ash mortar specimen.

  From the above , we understand the importance of slag and fly ash powder and asphalt concrete mix in , so for the preparation of slag and powder , etc. also need to attach great importance to choose ore milling machine for asphalt concrete needs of requirements for optional filler , VIPEAK Heavy series with new mill Raymond mill , for example, it can be processed ore 80-325 mesh fineness between asphalt concrete mix is more reasonable to procure asphalt concrete realize the value of their performance in the highway construction.
