Abstract

A superlight shale haydite is prepared from pelitic shale through mixing with water, stirring, granulating, preheating from 12 deg.C for 40-45 min, calcining at 1300-1450 deg.C for 2-5 min, and cooling. Its advantages are high stack density up to 200 Kg/cu.m, superlight weight, high strength and good heat insulation.

Description

The production method of super-light shale ceramsite
Technical field
The invention belongs to building material field, be specifically related to a kind of production method of lightweight wall body building material haydites of book structure.
Background technology
At present, China's construction material is many to be mixed and fired common brick based on silt or plaster, has not only wasted a large amount of lands used that fetches earth, and has also wasted a large amount of energy.Developed the walling unit that some light materials are made in recent years in succession, and the most of haydite producing technologies one of the raw materials for production of these building blocks to be requirement have strict numerous and diverse batching, the 2nd, need to add whipping agent or fusing assistant, simultaneously, its tap density is many at 300kg/m 3More than the level, the tap density that had both made the present zeolite ceramsite of generally producing, graptolitic facies haydites of book structure is all at 300kg/m 3About level, be difficult to satisfy the requirement of building material to the light shale haydite.
Summary of the invention
The object of the present invention is to provide a kind of tap density to reach 200kg/m 3Level is with the production method of the raw material haydites of book structure of interior ultralight matter, insulation, high-intensity novel wall material.
Technical scheme of the present invention is:
1) select high quality raw material: exploitation contains clay mineral composition total amount greater than 40% mud shape shale, and based on illite, montomorillonite, kaolinite, zeolite are auxilliary;
The shale chemical compositions by percentage is: SiO 2Be 56.2～59.1%, Al 2O 3Be 15.7～17%, Fe 2O 3Be 7.2～8.1%, CaO is 3.1～4.3%, and WgO is 2.5～3.2%, SO 3Be 0.04～0.06%, loss on ignition is 7.9～8.3%.
2) raw material is sent into stirrer and add the moisture content of raw material weight 10～12%; fully stir; guarantee that total water content is about 40～45%; send into tablets press after stirring and cause grain; particle is the long ball type, and its major diameter is 10～15mm, and the minor axis diameter is 5～10mm; raw material after the granulation needs the roller screen screening, and diameter is less than 3mm returning stirrer through conveying belt and reuse greater than 20mm.Qualified particle is sent into the revolution cellar for storing things.With the water of above-mentioned raw materials adding 10～12%, put into stirrer and fully stir, material moisture content is mixed;
3) through screening qualified particle being sent into the revolution cellar for storing things fires through giving the torrid zone and clinkering zone, 47 meters of rotary kiln length overalls, 2.1 meters of diameters, give about 40 meters of the torrid zone, all the other are clinkering zone, give tropical temperature and raise gradually since 120 ℃, give heat and enter clinkering zone after 40～45 minutes, 1300～1450 ℃ of burning zone temperatures, firing time 2～5 minutes; The rotating speed at revolution cellar for storing things is controlled at 1.5 rev/mins, and exhaust air rate is 27000～31000 cubic metres/minute, and this moment, the shale particle fully expanded, and was fired into the haydite diameter at 5～25mm, uses high-quality raw coal, thermal value to require to reach more than the 25000KJ/Kg in calcination process;
4) haydites of book structure after burning till flows into cooling drum, and be 5～8 minutes cooling time, and the temperature of haydites of book structure is reduced to below 100 ℃, can put in storage through check.
The technical indicator that haydites of book structure of the present invention reaches:
Tap density :≤200kg/m 3Cylindrical compress strength: 〉=0.2Mpa
Averageparticle type coefficient :≤1.6 water-intake rates :≤30%
SO 3:≤1% organic impurities: be not deeper than reference colour
Silt content :≤3%
Super-light shale ceramsite of the present invention, the material grain of extruding has certain intensity, in order to avoid it is cracked to advance kiln calcining, material is heated evenly in rotary kiln, improves thermo-efficiency, it is even to burn haydite swelling; Haydites of book structure of the present invention has good characteristics such as light weight, insulation, sound insulation, and quality product is higher.
200kg/m of the present invention 3Level light shale haydite is joined 400kg/m 3The little building block wall thickness of level haydite concrete can reach 350～400mm, has alleviated wall weight, increases effective usable floor area, and heat transfer coefficient reaches the requirement of 0.52w/m.k limit value.
