Embodiment 1
[0026] Use aluminum profile factory industrial sludge, clay, talc and barium carbonate as raw materials to prepare wear-resistant ceramic balls. The raw material formula is as follows: 67% of aluminum profile factory industrial sludge calcined at 1300°C, 20% of clay, 9% of barium carbonate, Talc powder 4%, firing temperature: 1380°C, holding time 3 hours.
[0027] Preparation steps: a. Calcining industrial sludge from an aluminum profile factory at a high temperature of 1300°C;
[0028] b. After mixing the raw materials according to the above formula, put the mixed raw materials into the ball mill according to the ratio of 1 part of the mixture, 1.5 parts of the grinding medium, and 0.9 parts of water, and grind for 20 hours to obtain the slurry;
[0029] c. After filtering the ground slurry with a 200-mesh screen, drying and dehydrating the slurry to make a powder with a moisture content of 5% to 7%;
[0030] d. After molding the powder, it is made into semi-finished blanks ...
