Dry clay preparation process
Since it is done using impact or percussion, the dry milling and grinding of clay will always be more effective with dry, hard clays than with wet, soft clays, which absorb part of the energy of the impact due to yield, thereby reducing the effectiveness of the process.
Therefore, it is advisable to use dry processing:
- - For clays with a moisture content under 12%.
- - For clays with high limestone content, in order to minimise the presence of "lime blows" in the finished pieces.
- - When you want to produce a quality ceramic product, such as floor and roof tiles, facing bricks, etc.
