Attapulgite clay be a kind of layer of chain-like structure containing Shuifu County's zeopan clay mineral, attapulgite clay soil property exquisiteness, water-absorbent is strong, tool viscosity and plasticity-when wet, be conducive to the bonding between raw material, can improve the sticking power of Attapulgite volcanoclastic rock alkalescence raw meal powder.
High sticky attapulgite clay powder refers to gets 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add again 372g water, the suspension cup is placed on homogenizer, under the rotating speed of 11000 rev/mins, stir 20 minutes, 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 be tested its suspension, tested viscosity value>=2200 into
mPasthe attapulgite clay powder be high sticky 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, as a kind of attapulgite clay mine tailing, abandon, cause a large amount of wastings of resources, more containing magnesian amount in the rhombspar attapulgite clay, and quality is harder, the rhombspar attapulgite clay mine tailing particle fineness that the present invention selects≤1.0 millimeters.
Volcanoclastic rock is the rock of the transitional type between magma lava and sedimentogeneous rock, wherein the composition more than 50% is comprised of the material of pyroclastic flow ejection, and these tephras are mainly the lava of premature coagulation on volcano, the rock formation that passage is burst on every side when volcanic eruption.The volcanoclastic rock mixture comprises landwaste, brilliant bits, glassiness bits, slurry bits, volcanic block (diameter is greater than 100 millimeters), volcanic gravel (diameter is greater than 2 millimeters) and volcanic ash (diameter is less than 2 millimeters), the volcanoclastic rock main chemical compositions is silicon-dioxide and aluminum oxide, there is fire performance and the intensity that increases Attapulgite volcanoclastic rock alkalescence raw meal powder, the volcanoclastic rock particle fineness that the present invention selects≤5.0 millimeters preferably.
Magnesite is a kind of magnesiumcarbonate mineral, and it is the main source of magnesium, the using magnesite granule fineness that the present invention selects≤2.0 millimeters.
Serpentine is high magnesium mineral, has heat-resisting, anticorrosive, wear-resisting, heat insulation, sound insulation, operational characteristic preferably, the serpentine particles fineness that the present invention selects≤2.0 millimeters.
The rock that wilkinite mainly is comprised of wilkinite, it is the important raw mineral materials of field of metallurgy, the wilkinite mine tailing that the present invention selects is distributed in the lower floor in attapulgite clay ore deposit mostly, be difficult to carry out independent exploitation, but the content of aluminum oxide >=16% in the wilkinite mine tailing, and there is plasticity-and agglutinating value(of coal), the bentonite clay particle fineness that the present invention selects≤1.0 millimeters.
