Dear R and P Having faced this problem with our 2-Up brick machine albeit at much higher pressures I found the answer is a robust machine and operator training. After a time the operators just get good at loading the cavities. It was very important to our production process that the mix NOT be a slurry because of the extended drying needed, though it is a workable idea.
In Lubumbashi 205 workers using 41 manual machines made 1.3 million bricks in one month (Oct 2010) using 11% moisture clay. The cavities are filled individually but compressed in pairs. I was as impressed as the frogged side of the bricks! I concur that the mix is critical but people get very good at the art of batching...
