The production method of spherical attapulgite refractory ceramsite: the batching of spherical attapulgite refractory ceramsite is packaged as spherical attapulgite refractory ceramsite through mixing, granulation, roasting, cooling and screening.
Attapulgite clay be a kind of layer of chain-like structure contain Shuifu County's zeopan clay mineral, the attapulgite clay soil property is fine and smooth, and water-absorbent is strong, tool viscosity and plasticity-when wet, be conducive to the bonding between raw material, can improve granule strength, sticking power and the porosity of spherical attapulgite refractory ceramsite.
High sticking attapulgite clay powder refers to get 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add again 372g water, the suspension cup is placed on homogenizer, stirred 20 minutes under the rotating speed of 11000 rev/mins, to pour in the beaker of 250ml through the high-speed stirring sample suspension again the viscosity of using NDJ-1 type rotational viscosimeter to test its suspension, tested viscosity value 〉=2200 into
MPasThe attapulgite clay powder be high sticking attapulgite clay powder, the height that the present invention selects glues attapulgite clay powder particles fineness≤0.074 millimeter.
Attapulgite clay can mix in recovery process a certain amount of rubble and earth, can't sieve, and abandons as a kind of mine tailing, causes a large amount of wastings of resources, and the present invention pulverizes the attapulgite clay mine tailing and is mine tailing, particle fineness≤0.10 millimeter.
The slag of blast furnace ironmaking melting flows directly in the pond cooling, has little time crystallization and the glass state material that forms, is granuliform granulated blast-furnace slag, is commonly called as grain slag; Granulated blast-furnace slag contains the oxide compound of calcium, silicon, aluminium, magnesium, manganese, iron etc.; be conducive to improve intensity and the fire performance of spherical attapulgite refractory ceramsite; granulated blast-furnace slag also has potential hydraulic gelling property, and the present invention selects the particle fineness of GBFS≤0.10 millimeter.
Iron tailings is dressing-works remaining solid waste after selecting concentrate, it is a kind of composite minerals raw material, its chemical composition is mainly take the oxide compound of iron, silicon, magnesium, calcium, aluminium as main, be conducive to improve intensity and the fire performance of spherical attapulgite refractory ceramsite, the mine tailing granularity that most of ore dressing is discharged is thinner, and the present invention selects the particle fineness of iron tailings powder≤0.10 millimeter.
Coal gangue is the solid waste that discharges in coal mining process and coal washing process, be a kind of lower with a kind of carbon content of coal seam association in coalification course, have a lower heating value, carbon containing 20～30%, can save part coal, and forming micropore at haydite, the present invention selects the particle fineness of colliery powder≤0.10 millimeter.
Bauxite gangue aluminium sesquioxide content is higher, is conducive to improve intensity and the fire performance of spherical attapulgite refractory ceramsite, the particle fineness of bauxite gangue powder≤0.1 millimeter.
