1. The moisture content of the mud material is high or low. If it is too high, it is easy to cause rolling head marks on the forming surface of the green body. If the center of the rolling head coincides with the center of the green body, and the speed ratio is inappropriate, it will also cause the rolling head to be sharp and small. The range of slime forms a depression, and if it is too low, it is easy to produce shock marks.
