Industrial Vacuum Brick Extruder Machine with Vacuum De-airing System Adjustable Mold and Automated Control for Hollow and Solid Bricks

The vacuum brick extruder serves as the core equipment in clay brick production, designed 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 overall plant operational stability.

• Vacuum De-airing System: Achieves -0.092 to -0.098 MPa vacuum pressure to remove air from clay, reducing porosity and preventing cracking during drying and firing processes.
• High-Pressure Extrusion System: Utilizes spiral auger or two-stage mechanism with 2.5-4.5 MPa pressure range for homogeneous clay compaction across varying material hardness.
• Adjustable Mold System: Quick-change mold configuration enables production flexibility for solid, hollow, or perforated bricks with minimal downtime.
• Wear-resistant Construction: High-chromium alloy steel or tungsten carbide coatings on critical components (auger, liner, extrusion head) extend service life, with hydraulic clearance adjustment in premium models.
• Automated Control: PLC-controlled systems monitor vacuum level, extrusion pressure, and motor load, with advanced models offering remote monitoring for predictive maintenance.

• Material Processing: Mixes and extrudes clay, shale, or coal gangue mixtures
• De-airing: Removes air bubbles to enhance structural integrity
• Precision Shaping: Forms bricks via interchangeable dies for various profiles
• Integrated Cutting: Optional auto-cutting system for consistent brick lengths
• Material Conveying: Transfers formed bricks to drying or stacking systems

• Superior Quality: Reduces waste rate from >10% to <2% by eliminating cracks and deformation
• Energy Efficiency: Optimized pressure systems with VFD technology save 20%+ in power consumption
• Durability: Extends component lifespan from 3-6 months to 1-3 years, reducing maintenance costs
• Material Adaptability: Handles clay with 14-22% moisture content and mixed additives
• Process Optimization: Minimizes downstream issues like drying cracks and firing deformations

As the heart of brick manufacturing operations, selecting a reliable vacuum extruder ensures superior product quality, reduced operational costs, and long-term production efficiency. Our high-performance machines deliver consistent results through advanced engineering and durable construction.
