The mixing drum of the unburned brick machine is driven by a gear ring, and when working, it rotates forward for mixing and reverses for discharging. It can mix plastic and semi dry hard concrete, suitable for general construction sites, roads, bridges, water and electricity projects, and small and medium-sized concrete component factories. The non fired brick machine has a reasonable structure and advantages such as high production efficiency, good mixing quality, beautiful appearance, and convenient movement. It is a relatively advanced model.

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.
