The machine is a vacuum hard plasticity extruder manufactured according to American technology. The output per hour is 14000-22000, and the brick machine apply gear box with hard tooth surface. The structure of the machine is rigid. The auger and rimer is made of high-chromium alloy and have good wear resistance. When the hardened gearbox is used, the transmission efficiency is high. High production and low consumption, due to large extrusion pressure, it effectively improved the wet strength of the product. It is suitable for producing sintered products such as gangue, fly ash, shale, tailings and slag as raw materials for decorative bricks, and heat-insulating sintered bricks.
