High-Efficiency Vertical Screw Extruder with 30% Energy Saving and Vertical Double Helix for Brick Production

This series of machines is manufactured using advanced European technologies, specifically designed for the extrusion molding of high-end ceramic materials, cement fiber products, and semi-rigid plastic viscous materials. The equipment's materials, technical structure, electrical systems, and operating systems are all produced in accordance with European standards.

Vertical Double Helix Vacuum Extruder is a core forming equipment in clay sintered brick production, mainly used to extrude homogenized clay materials into brick blanks with specific cross-sectional shapes.

• Vertical double helix structure: Two screw shafts arranged vertically, rotating in opposite or same directions to apply continuous extrusion and shearing forces on materials, ensuring uniform mixing and air discharge.
• Vacuum system: A vacuum chamber removes air bubbles from materials (typically with a vacuum degree of -0.08MPa to -0.095MPa) to improve brick blank density.
• Mold components: Replaceable extrusion molds determine brick blank shapes (standard bricks, perforated bricks, hollow bricks) for different product requirements.

• Efficient double-helix mixing: Shearing action crushes agglomerates and enhances plasticity, especially for high-viscosity clay.
• High-vacuum forming: Increases brick blank density by 10%-15% and reduces shrinkage deformation after sintering.
• Automated control: PLC system enables real-time adjustment of screw speed, vacuum degree, and extrusion pressure.
• Multi-functional mold adaptation: Quick mold replacement (≤30 minutes) for different brick types.
• Large-capacity design: 80,000-150,000 bricks per shift (8 hours), with large models reaching 200,000 bricks.

• Transforms mixed materials into uniform brick blanks for drying and sintering
• Improves product quality: Vacuum extrusion eliminates air holes, increasing brick strength (MU10-MU25)
• Connects with upstream and downstream equipment for continuous production
• Reduces material waste with precise extrusion control (≥95% utilization rate)

• Technical: 30% higher extrusion pressure than single-helix designs, stable vacuum control reduces porosity by 15%-20%
• Economic: 60% operator reduction, 12%-18% lower energy consumption per 10,000 bricks
• Maintenance: Wear-resistant alloy screw shafts (8,000-10,000 hour lifespan), automatic dust removal extends maintenance to 3,000 hour intervals
