[0071] Such as figure 1 As shown, one end of the ball mill mechanism 10 is a ball mill feed end 11, and the other end of the ball mill mechanism 10 is a ball mill discharge end 12;
[0072] Such as figure 2 As shown, the mixing preheating mechanism 20 includes a mixing mechanism housing 21, the inner wall of the mixing mechanism housing 21 is fixed with a first support ring 211, and the upper side of the first support ring 211 is fixed with a A second support ring 212, a damping washer 2110 is provided between the first support ring 211 and the second support ring 212;
[0073] Such as figure 2 As shown, a mixing hopper support ring 221 is provided above the second support ring 2...
Embodiment 2
[0102] Utilize a kind of aluminum ash slag among the embodiment 1 to activate the method for producing calcium aluminate by the production device of rotating molten calcium aluminate, comprise the following steps:
[0103] S1. Filtration and screening. First, simply crush the raw material of aluminum ash slag, so that the agglomerated aluminum ash in the raw material of aluminum ash slag can be broken, and then filter the raw material of aluminum ash slag after the simple crushing treatment, and use a 100-mesh sieve in turn. Net and 200-mesh sieve are used to filter the aluminum ash slag raw material;
[0104] S2, ball milling, the aluminum ash slag and the calcium oxide raw material filtered and screened in step S1 are respectively ball milled and pulverized, the particle size of the aluminum ash slag after ball milling is 26-38 μm, and the particle size of the calcium oxide is 21-48 μm;
[0105] S3, mixing raw materials, by weight, 40 parts of aluminum ash, 35 parts of calci...
Embodiment 3
[0111] Unlike Example 2, the method for producing calcium aluminate comprises the following steps:
[0112] S1. Filtration and screening. First, simply crush the raw material of aluminum ash slag, so that the agglomerated aluminum ash in the raw material of aluminum ash slag can be broken, and then filter the raw material of aluminum ash slag after the simple crushing treatment, and use a 100-mesh sieve in turn. Net and 200-mesh sieve are used to filter the aluminum ash slag raw material;
[0113] S2, ball milling, the aluminum ash slag and calcium oxide raw material filtered and screened in step S1 are subjected to ball milling treatment respectively, the particle size of aluminum ash slag after ball milling is 38-53 μm, and the particle size of calcium oxide is 48-74 μm;
[0114] S3, mixing raw materials, in parts by weight, 50 parts of aluminum ash, 40 parts of calcium oxide and 12.5 parts of limestone powder are respectively added from each of the feed pipes 273, after bei...
