Product Description:

Halstec double stage vacuum extruder is the core equipment in modern fired brick production lines, designed for high-efficiency extrusion molding of various raw materials including clay, shale, coal gangue, fly ash and other industrial solid wastes. Our advanced extruder adopts a two-stage structure with independent mixing and extrusion systems, combined with a high-performance vacuum degassing unit, which can effectively remove air bubbles from the raw material mixture, significantly improving the density, strength and uniformity of the green bricks.
With strong extrusion pressure, stable operation and low energy consumption, Halstec vacuum extruders are suitable for producing solid bricks, perforated bricks, hollow blocks and other various brick types. We offer a full range of models with production capacities from 10,000 to 50,000 standard bricks per hour to meet the needs of small, medium and large-scale brick manufacturing plants worldwide.

Features:

• Product Name: Double Stage Vacuum Extruder
• Design: Full Steel Structure for durability and strength
• Function: To extrude the mud strip out at the vacuum condition ensuring high-quality bricks
• Certification: CE/ISO certified for quality and safety
• Capacity: Produces 35,000-45,000 bricks per hour
• Warranty: One year warranty for reliable performance

Key Features:

1. High Vacuum Degassing System: Achieves vacuum degree up to ≤-0.092MPa, effectively eliminating air bubbles in the mud, preventing cracks, delamination and bursting during drying and firing processes, ensuring high-quality finished bricks
2. Powerful Extrusion Performance: Standard allowable working pressure 4.0MPa, suitable for both soft and hard raw materials, with uniform extrusion force and stable mud column output
3. Wear-Resistant Design: Key components such as spiral reamers, liners and machine heads are made of high-chromium alloy steel with wear-resistant coating, extending service life by 2-3 times compared to ordinary materials
4. Modular Structure: Compact and reasonable design, easy to install, operate and maintain. Quick-change mold system allows for rapid switching between different brick types, reducing downtime
5. Energy Saving & Environmental Protection: Optimized transmission system and rheological extrusion technology reduce power consumption by 15-20% compared with traditional extruders. Supports utilization of various industrial solid wastes, promoting circular economy
