Brick blank forming
- Jul 25, 2018 -

The powder in the press hopper passes through the cloth grille fabric and is pressed and formed by the brick press. The pressing process is divided into three steps:

The first step is to lightly pressurize the exhaust; the second step is to pressurize and then exhaust; in the third step, the pressure is added to the final.

Pressing to a blank that meets the density requirements is very detailed. First, the filler should be uniform; secondly, the pressing time and speed should be very accurate and controlled by the computer; then the demoulding is also very precise, otherwise cracking is likely to occur. Different press tonnages press different sizes of products, which determine the thickness, size, density, hardness and other parameters of the blank.

The tonnage of the press directly determines the density and hardness of the tile.
