Example Embodiment
[0057] Example 1
[0058] (1) Take 1100 kg of aeolian sand, add 660 kg of water into the continuous scrubbing mud machine, add 500 g of sodium silicate as an auxiliary agent for scrubbing, and the scrubbing time is 20 minutes to obtain 1000 kg of aeolian sand after scrubbing. After scrubbing and purifying the aeolian sand, the silica content was tested to be 98%. The aeolian sand after scrubbing is wet-milled with a stirring mill. The ceramic grinding media ball with a diameter of 1-10mm with low abrasion and high hardness is used. 2kg of sodium chloride additives are added and mixed, then stirred and rinsed. The time is 50 minutes, and the particle size index of the aeolian sand powder after wet grinding reaches 8-10μm;
[0059] (2) Take desulfurized gypsum with a particle size of 60μm (CaSO 4 ·2H 2 O content is 90%) 2500kg, 150kg of fixed carbon content is 88%, and coke powder with a particle size of 200 mesh (purchased from Shanxi Qingxu Coking Plant, trade number C90) is used ...
