Embodiment 1
[0024] A preparation method for making high-quality shell powder from discarded shells, comprising the following steps:
[0025] S1: Material preparation: Prepare waste shell materials, and clean the surface to remove all impurities and dirt attached to the surface;
[0026] S2: Cooking: Take out the cleaned shells, put them into the pot, and add the mixed supernatant to boil, quickly heat the water to 90°C, stir the shells in the pot during the heating process, when the temperature reaches 90°C After ℃, keep the high heat and continue to boil for 0.5h;
[0027] S3: Cold soaking: put the boiled shells into ice water to quickly cool down the high-temperature shells;
[0028] S4: crushing and drying: take out the cold soaked shells, press the shells into small pieces, put the small pieces of shells in a drying oven for baking, the temperature in the oven is kept at 80°C, and the baking time is 1h;
[0029] S5: Crushing: put the crushed and dried shell fragments into a ball mil...
