Product Description

Equipment Introduction:
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. Its structural features include:
Vertical double helix structure: Two screw shafts are 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 is set at the front of the extrusion section, removing air bubbles from materials by vacuuming (typically with a vacuum degree of -0.08MPa to -0.095MPa) to improve the density of brick blanks.
Mold components: Replaceable extrusion molds determine the cross-sectional shape of brick blanks (such as standard bricks, perforated bricks, hollow bricks, etc.), adapting to different product requirements.
Efficient double-helix mixing:
The shearing action of two screw shafts crushes agglomerates in materials and enhances plasticity, especially suitable for high-viscosity clay or clay with impurities.
High-vacuum forming: The vacuum system effectively removes gas from materials, increasing the density of brick blanks by 10%-15% and reducing shrinkage deformation after sintering.
Automated control: Equipped with a PLC control system, enabling real-time adjustment of screw speed, vacuum degree, and extrusion pressure to adapt to different material humidity (optimum humidity 15%-20%).
Multi-functional mold adaptation: Supports quick mold replacement for switching between standard bricks, KP1 bricks, perforated bricks, etc., with mold change time ≤30 minutes.
Large-capacity design: Conventional models have a capacity of 80,000-150,000 bricks per shift (8 hours), and large equipment can reach 200,000 bricks per shift to meet large-scale production needs.

Core Forming link:
Transforms mixed materials into uniform brick blanks, providing standardized blanks for subsequent drying and sintering.
Improve product quality: Vacuum extrusion eliminates air holes in materials, making the density of brick blanks uniform. After sintering, the strength of bricks is improved (MU10-MU25), and impermeability and frost resistance are significantly enhanced.
Connect production processes:  (Interacts) with upstream crushing and mixing equipment and downstream cutting and drying equipment to form a continuous production line, improving the degree of automation.
Reduce material waste: Precisely controls the extrusion amount, reduces errors in manual forming, and the material utilization rate can reach over 95%.
Technical advantages:
The double-helix design increases extrusion pressure by 30% compared with single-helix, suitable for high-hardness materials (such as shale and gangue mixed with clay).
The vacuum degree is stable and controllable, the porosity of brick blanks is reduced, and the thermal conductivity after sintering can be decreased by 15%-20%, meeting the standards of energy-saving bricks.
Economic advantages:
High degree of automation, reducing operators by more than 60% and lowering labor costs (compared with traditional manual extrusion).
Significantly improved production capacity, with unit energy consumption (kWh/10,000 bricks) reduced by 12%-18% compared with traditional equipment.
Maintenance advantages:
The screw shaft is coated with wear-resistant alloy (such as tungsten carbide), with a service life of 8,000-10,000 hours and convenient replacement.
The vacuum system is equipped with an automatic dust removal device to reduce dust blockage, extending the maintenance cycle to 3,000 hours per time.
