Embodiment 1
[0014] a, getting particle size by weight is 80% of 15 purpose bauxite pellets (will contain AI 2 o 3 70%-80% of bauxite is crushed by a crusher and a pair of rollers, and then screened by a vibrating sieve), 7% of 250-300 mesh clay fine powder, 6% of talcum powder, and 7% of bentonite. 5%-8% water by weight is fully stirred for about 30 minutes;
[0015] b. Put the stirred mixture into the mold and carry out vibration molding under the pressure condition of 500-800 tons, and the time is controlled within 10-15 seconds;
[0016] c. Send the shaped bricks into the drying room for drying:
[0017] d. Carry out kiln calcination for the dried brick adobe, the temperature is controlled between 1250-1280°C, and it is enough to keep it for 100-120 minutes.
[0018] The product that the present embodiment produces is the common floor tile without color.
Embodiment 2
[0020] a. Take the bauxite powder with a particle size of 300 mesh by weight and add 90%-96% of bauxite powder with 4%-8% grass green dye additive, add the water of 4%-8% of the above-mentioned total weight and carry out sufficient stirring. After mixing, add Molding, drying and calcining according to the traditional process, and then crushing to make grass green bauxite pellets of about 20 meshes;
[0021] b. Take 80% of grass green bauxite granules, 7% of 250-300 mesh clay fine powder, 6% of talcum powder, and 7% of bentonite by weight, and add 5%-8% of the above-mentioned total weight of water to fully stir , the time is about 30 minutes;
[0022] C, getting particle size by weight ratio is 80% of 15 purpose bauxite pellets (will contain AI 2 o 3 70%-80% of bauxite is crushed by a crusher and a pair of rollers, and then screened by a vibrating sieve), 7% of 250-300 mesh clay fine powder, 6% of talcum powder, and 7% of bentonite. 5%-8% water by weight is fully stirred for...
