The process of producing bricks using a vacuum brick machine: The clay is stirred with a clay mixer, mixed with some sand and stone powder, evenly mixed, and then transported to a vacuum brick machine through a conveyor belt. After being compressed by a vacuum brick machine under vacuum pressure, the bricks are formed. After the bricks are produced, they are cut into evenly sized bricks through a dividing machine, and then automatically grabbed by a palletizing machine, placed in a kiln car, and fired in a furnace.

The bricks produced by vacuum brick machines are mainly made of clay, and the production process is simple, but the damage to arable land is relatively serious. In 2015, the country successively introduced policies prohibiting the production and use of clay bricks, and vigorously promoted the reuse of solid waste. And brick products using fly ash as the main production raw material and gypsum and quicklime as the main bonding materials are gradually replacing traditional clay bricks.
