Embodiment 1
[0022] The manufacturing method of the glazed ceramic exterior wall brick of the present embodiment adopts the following raw materials to make: 28 tons of clay, 25 tons of Tongfu soil, 22 tons of stone rice, and 25 tons of potassium sand, wherein the total aluminum content of the raw materials is 14.5%, Total iron content 2%;
[0023] Its manufacturing method comprises the following steps:
[0024] A. Add the raw materials calculated in the above ratio and 10% water of the total amount of raw materials into a ball mill to grind to a particle size of 45 μm to 50 μm, and then remove the iron from the slurry and sieve it, then use a spray drying tower to spray dry it into Granules, put the pellets into a sealed iron bucket, stale for 48 hours until the moisture content of the pellets is 7.5%;
[0025] B. Under the pressure condition of 180MPa, use a press to press the stale material in step A into a green body, and the green body is dried at a temperature of 200°C to obtain a br...
