Description
Technical field
The present invention relates to building waste processing technology field, brick mixes separation work to more particularly, to a kind of building castoff twice
Skill.
Background technology
Building castoff regeneration technique is all：Raw material → broken → sorting → broken → screening → finished product, this work
Skill simply simply becomes fritter it is impossible to the brick building castoff and concrete are separated profit building castoff from bulk crushing
With.
The utilization rate of the material after the above-mentioned PROCESS FOR TREATMENT of prior art is low, and added value is low, and in reality, enterprise is to building
Offal treatment is little using income, and enthusiasm is low, is unfavorable for environmental conservation.
Content of the invention
For overcoming the above-mentioned technical problem of prior art presence, the invention provides a kind of building castoff mixed point of brick twice
Separating process, it carries out to the brick in building castoff and concrete separating, and can farthest utilize concrete regenerating to utilize
