The vacuum brick extruder is the core equipment in clay brick production, primarily used to extrude mixed clay materials under high pressure while applying vacuum treatment to enhance the compactness and strength of the green body. Its performance directly impacts brick quality, production efficiency, and the overall operational stability of the entire plant.

• Vacuum De-airing System: Removes air from the clay (typically achieving -0.092 to -0.098 MPa) to reduce body porosity and enhance density, preventing cracking during drying and firing.
• High-Pressure Extrusion System: Utilizes spiral auger or two-stage extrusion mechanism (2.5-4.5 MPa pressure) for homogeneous clay compaction.
• Adjustable Mold System: Quick-change mold systems enable production flexibility for various brick dimensions and profiles.
• Wear-resistant Materials: High-chromium alloy steel or tungsten carbide coatings on critical components for extended service life.
• Automated Control: PLC-controlled systems monitor vacuum level, extrusion pressure, and motor load for intelligent adjustment.

• Mixes and extrudes clay materials (including shale or coal gangue)
• Removes air bubbles to enhance brick strength
• Forms bricks via dies (solid/hollow blocks)
• Integrated auto-cutting for precise brick lengths
• Transfers bricks to drying or stacking systems

• Improves brick quality with waste rate reduced to <2%
• Boosts efficiency with 24/7 production capability and 20%+ energy savings
• Extends component lifespan to 1-3 years, reducing maintenance costs
• Adapts to various raw materials (14-22% moisture content)
• Minimizes drying cracks and firing deformations

As the "heart" of a brick plant, choosing a reliable, wear-resistant, automated vacuum extruder ensures higher quality production, lower operational costs, and long-term competitiveness.
