Step 2, broken: the discarded clay brick material after step 1 separates is crushed by disintegrating apparatus, prepared size≤ The block brick material of 50mm；
Step 3, two grades are removed ferrum: by concentration equipment, step 2 gained bulk brick material is removed irony material further；
Step 4, dispensing and grinding: through step 3 except the block brick material of ferrum is by milling equipment grinding, press in grinding process Certain proportioning adds chemical activator, prepares specific surface area >=500m2The clay brick powder of/kg.
Step 5, batch mixing preparation: step 4 gained clay brick powder allocates slag micropowder into by certain volume, mix through mixing equipment Uniformly, ecological Binder Materials is prepared.
In described step 1, construction waste clay brick material obtains from building waste in the following way:
By loader, building waste is fed apron feeder, and building waste is sent into separator by apron feeder, profit Sand discarded in building waste, discarded clay brick, discarded concrete being separated by volumetric method, formation construction waste sand material, building are useless Abandon clay brick material and three kinds of primary product of construction waste concrete material；Wherein, the main component of described construction waste clay brick material For discarded clay solid brick, also comprise very small amount particle diameter≤70mm concrete block.
In described step 1, also include except ferrum, light materials separate, before feed of crusher, by concentration equipment and light materials Sorting unit removes irony material and light materials.
In described step 4, milling equipment is Vertical Mill.
In described step 4, chemical activator is Gypsum Fibrosum, Calx, triisopropanolamine and the one of diethanol monoisopropanolamine Planting or several, addition is: Calx 1.5～7.5%, Gypsum Fibrosum 4～6%, triisopropanolamine 0.015～0.03%, diethanol Monoisopropanolamine 0.015～0.03%, is the percentage by weight of step 3 gained bulk brick material.
In described step 5, described slag micropowder volume is the 0%～40% of clay brick opaque amount, described slag micropowder Specific surface area >=450m2/kg。
Compared with prior art, the invention has the beneficial effects as follows:
(1) present invention uses construction waste clay brick to produce ecological Binder Materials, alleviates resource, the energy and ambient pressure, There is significant social benefit.
(2) present invention uses vertical mill grinding technique, collects drying, grinding, selects powder one, low-carbon energy-saving environmental protection.
(3) present invention is by rational physics and chemical activation approach, efficiently excites the potential work of construction waste clay brick Property.
(4) the ecological Binder Materials activity using the present invention to prepare is high, added value is high, steady quality, can large-scale popularization make With.
