Description
Technical field
The present invention relates to the material of construction processing technique field, be specifically related to a kind of mixed regeneration aggregate flour production line and milling method thereof.
Background technology
That waste material of buildings is promptly built is newly-built, reconstruction, remove and the waste and old material of construction that produces.It is waste and old building demolition and the waste material of buildings that produces that the present waste material of buildings resource utilization of China is utilized main task again.Because the leading composition of the building construction refuse that China removes is that master, concrete are auxilliary with the vitrified brick, so, comprise a large amount of brickbats through mixed regeneration aggregate broken, that sieve, go soil, impurity elimination, deironing etc. to deal.This mixed regeneration aggregate is unsuitable to be used as the concrete skeleton structured material.But this suitable deep processing of mixed regeneration aggregate that contains a large amount of chainotte materials becomes regenerative micro powder, uses as various cement based building materials adulterants.The chainotte material has pozzolanic activity, uses as adulterant and can reduce cement consumption, promotes the recycle value of waste and old sintered clay brick greatly.
Owing to the mixed regeneration aggregate that with the vitrified brick is the master has characteristics such as mixed, assorted and wet, adopt the traditional grinding production line of building material industry, all can not satisfy mixed regeneration aggregate powder process needs, there are energy consumption height, inefficient problem, also being difficult to realize classification regeneration.The milling equipment of building material industry has three kinds on high pressure roll press, vertical mill and ball mill usually, adheres to squeezing mill separately, rolls three kinds of mill and ball millings.Above-mentioned three kinds of grinding machines commonly used can not adapt to building waste powder process requirement fully.
High pressure roll press does not use as the terminal mill usually; Because the powder that high pressure roll press grinds mainly is a sheet and acicular; So the powder shape that high pressure roll press grinds is bad, this high pressure roll press also exists the powder fineness that squeezes out not enough, the shortcoming that flour extraction rate is lower.
Vertical mill is to being abstained from by metal object in the grinding material, owing to not guaranteeing definitely that the waste material of buildings mixed regeneration aggregate that gets into vertical mill does not contain tiny metal objects such as iron nail usually, so the application of vertical mill is restricted.
The ball mill investment is big and energy consumption is high, so efficient is relatively low.
Vertical mill and ball mill are that micro mist is all worn in charging; Because natural gravel and river sand in the mixed regeneration aggregate belong to inert material, and it is worn into micro mist, can cause the regenerative micro powder activity not high; And natural gravel and river sand intensity height, the energy consumption that they are clayed into power is higher.
How the mixed regeneration aggregate is ground required fineness, with the micro mist classification that is ground out, the equipment energy consumption of producing micro mist is low, output is greatly the problem that those skilled in the art need solve.
