At present, all ceramic product manufacturers generally use the sieving method to measure the particle size of ceramic mud. The specific method is: put various block materials into the ball mill barrel in a certain proportion, add a certain proportion of water, seal the charging port, and perform ball milling. After the ball mill barrel rotates for a period of time, stop the ball mill barrel, discharge a small amount of ceramic slurry from the discharge port of the ball mill barrel, put the ceramic slurry in a drying box to dry, weigh it with a balance after drying, record this value, and then weigh it.
