Description
Technical field
The present invention relates to construction material processing technique field and in particular to a kind of mixed regeneration aggregate flour production line and its
Milling method.
Background technology
Waste material of buildings builds waste and old construction material that is newly-built, reconstructing, remove and produce.China's current waste material of buildings resource
Change the waste material of buildings recycling main task to be waste and old building demolition and producing.Because the building construction waste that China removes is dominated
Composition is based on fired brick, supplemented by concrete, so pass through and crushing, sieve, going soil, roguing, the mixing dealing except ferrum etc.
Regeneration aggregate, comprises a large amount of brickbats.This mixed regeneration aggregate is not suitable for using as concrete skeleton structural material.But this
Plant the suitable deep processing of mixed regeneration aggregate containing a large amount of burnedc lay materials and become regenerative micro powder, blend as various cement based building materials
Material uses.Burnedc lay material has pozzolanic activity, uses and can reduce cement consumption as admixture, greatly promotes waste and old sintering
The recycle value of clay brick.

Shape, so the powder body shape that high pressure roll press grinds is bad, also there is the powder fineness deficiency squeezing out in this high pressure roll press,
The relatively low shortcoming of flour extraction.
Vertical mill is abstained to by metal object in grinding material, due to generally can not absolute guarantee enter vertical mill building give up
Thing mixed regeneration aggregate does not contain the fine metal things such as iron nail, therefore the application of vertical mill is restricted.
Ball milling speculative investment is big and high energy consumption, thus relatively inefficient.
Vertical mill and ball mill are charging all to be worn into micropowder, due to the natural gravel in mixed regeneration aggregate and fluvial sand
Belong to inert material, worn into micropowder, regenerative micro powder activity can be caused not high, and natural gravel and fluvial sand intensity are high, will
The energy consumption that they are clayed into power is higher.
