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.
