Clear-headed understanding, does not ensure that mixings time of the Lu Limei in action of forced stirring tank is in suitable area typically without suitable means
Between.
More Lu Limei are added, cost is on the one hand added, the miberal powder content in compound is on the other hand reduced, gives
The overall performance of bituminous concrete brings adverse effect.Inventor creatively have developed pressure and feed intake according to above new knowledge
Device, charging time was compressed within 1 second, while not influenceing charging tank to feed.If charging time can not be compressed, it can carry
Gao Lulimei breakage rate.Such as charging time is 4 seconds, then in order to ensure that Lu Limei is wrapped up by pitch, then must throw
Material is persistently stirred 8 seconds after terminating, for being put into the Lu Limei of action of forced stirring tank in feed intake first second, actually
The time stirred in action of forced stirring tank has just reached that breakage rate is very high 12 seconds.
Using the structures and methods of the present invention, charging time was compressed within 1 second, has both ensured Lu Limei by pitch institute
Parcel, prevents mixing time is long to cause Lu Limei breakage rates too high again.
In a word, using the structures and methods of the present invention, it is ensured that Lu Limei will not be damaged during conveying and stirring
Rate is too high, reduces Lu Limei consumption, both significantly cost-effective without the content of miberal powder in compression asphalt, and just
Transformed, and evenly rationally provided for bituminous concrete integral formula on the basis of existing bituminous concrete mixing building
