Product Description
Automatic Clay Brick Extruder Compatible with Solid/Hollow/Perforated Brick Production
Brictec offers four types of clay fired brick extruders: Large-scale Dual-Stage Vacuum Extruder, Medium-scale Dual-Stage Vacuum Extruder, Compact Extruder, and Vertical Screw Extruder. Each model has distinct performance parameters. For detailed specifications, please refer to the table below or consult with your account manager.
Equipment Introduction
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.
Key Features of Vacuum Extruder
- Vacuum De-airing System: Removes air from clay (typically achieving -0.092 to -0.098 MPa) to reduce porosity and enhance density, preventing cracking during drying and firing.
- High-Pressure Extrusion System: Uses spiral auger or two-stage mechanism (2.5-4.5 MPa pressure) for homogeneous clay compaction across varying hardness levels.
- Adjustable Mold System: Quick-change molds enable production of solid, hollow, or perforated bricks with minimal downtime.
- Wear-resistant Materials: Critical components use high-chromium alloy steel or tungsten carbide coatings for extended 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 supporting remote monitoring for predictive maintenance.
Primary Functions
- Material Processing: Mixes and extrudes clay (including shale or coal gangue mixtures)
- De-airing: Removes air bubbles to enhance structural strength
- Shaping: Forms bricks via customizable dies (solid/hollow blocks, etc.)
- Cutting: Some models integrate automatic cutting for precise brick lengths
- Conveying: Transfers finished bricks to drying or stacking systems
Operational Advantages
- Improves Brick Quality: Reduces waste rate from >10% to <2% by preventing cracks and deformation
- Boosts Efficiency: Enables 24/7 production with optimized pressure reducing power consumption by 20%+ (VFD models)
- Extends Lifespan: Premium models last 1-3 years vs. 3-6 months for cheap extruders
- Material Adaptability: Handles clay with 14-22% moisture content and mixed materials
- Process Optimization: Minimizes drying cracks and firing deformations in downstream processes
