Embodiment 1
[0032] Raw material weight composition is as follows: low-content bauxite (Al 2 o 3 Content is 60-65%) 86 parts, manganese ore (MnO 2 Content 40-50%) 3 parts, potassium feldspar (SiO 2 68%, Al 2 o 3 18%, K 2 O 14%) 3 parts, solid water glass (Na2O.3SiO2) 3 parts, calcium stone powder (CaO content 57%) 4 parts, talcum powder (Mg 3 [Si 4 o 10 ](OH) 2 ) 2 copies.
[0033] Grind the above-mentioned mineral components by weight into fine powders with an ultra-fine Raymond mill, pass through a 325-mesh sieve, mix and stir evenly, enter the ball mill for grinding, and then add to the rolling granulator for granulation, and at the same time Add atomized water vapor, and stop atomizing after 50 minutes. At this time, the mixture has formed round particles of different sizes; continuously and evenly add talcum powder for planing. Rotate further and pass through a 140-mesh sieve to obtain a semi-finished product, put the semi-finished product into a sagger, send it into a tun...
Embodiment 2
[0038] The weight composition of raw materials is as follows: 88 parts of low-content bauxite, 4 parts of manganese ore, 3 parts of potassium feldspar, 4 parts of solid water glass, 5 parts of calcium stone powder, and 4 parts of talcum powder.
[0039] The preparation method is the same as in Example 1.
Embodiment 3
[0041] The weight composition of raw materials is as follows: 82 parts of low-content bauxite, 2 parts of manganese ore, 2 parts of potassium feldspar, 2 parts of solid water glass, 3 parts of calcium stone powder, and 2 parts of talcum powder.
[0042] The preparation method is the same as in Example 1.
