Prior to extrusion, a vacuum pump (typically achieving -0.092 to -0.098 MPa) removes air from the clay, reducing body porosity and enhancing density. This prevents cracking, delamination, or explosion during drying and firing.
Utilizes a spiral auger or two-stage extrusion mechanism to ensure homogeneous clay compaction. Extrusion pressure typically ranges from 2.5 to 4.5 MPa, accommodating clay materials of varying hardness.
The mold determines brick dimensions and profiles (e.g., solid, hollow, or perforated bricks). High-performance extruders feature quick-change mold systems to minimize downtime and enhance production flexibility.
Critical components (auger, liner, extrusion head) utilize high-chromium alloy steel or tungsten carbide (WC) coatings for extended service life. Premium models incorporate hydraulic clearance adjustment to automatically compensate for wear, maintaining stable extrusion pressure.
Modern vacuum extruders feature PLC-controlled systems monitoring vacuum level, extrusion pressure, and motor load for intelligent adjustment. Advanced models support remote monitoring for predictive maintenance and fault alerts.
