MECHANICAL EXTRUSION
The clay is mixed inside the brick press through a series of pug mills and augers and extruded through a rectangular nozzle out onto a table where the billet of clay is cut into brick. This is usually done by wire, hence the name “wire cut”.
SEMI-DRY PRESS
Clay (or shale) is ground to powder, then a measured amount of powder mixed with water into a mould which is then compressed at least twice to form a brick. The material is consolidated into a brick by pressure.
STIFF PLASTIC
Clay is ground to powder and mixed with some water. It is fed into a mould in which the clot is compressed to form a brick.
