The compact extruder is a single-stage vacuum brick machine engineered for small-to-medium clay fired brick plants. It eliminates the conventional upper mixing section and is rigidly bolted to the upstream mixer/extruder mouth, creating a one-piece structure that greatly shortens overall length and reduces building height requirements.

Used to vacuum-extrude pre-treated clay, shale, or coal-gangue mixes into wet brick blanks in one pass, ready for cutting, stacking, drying, and firing downstream.

• Vacuum degassing: achieves -0.08 MPa vacuum to remove air, increasing blank density
• Continuous extrusion: direct coupling with the upstream mixer ensures steady, uninterrupted output
• Space-saving: overall machine length is ~30% shorter than traditional two-stage extruders, ideal for retrofits or height-limited plants

• One-piece mouth eliminates mud leakage, boosting forming rate to >98%
• Compact vacuum chamber cuts energy use by ~15%
• Quick-change die head allows mold switch in 30 min
• Low-noise operation ≤75 dB(A)

This compact extrusion brick machine is most suitable for the following two types of scale of clay brick factories:

• Small-to-medium brick plants (3,000-20,000 t of finished bricks per year, operating in one or two shifts)
• Retrofit projects with limited building height or length, or emergency/short-term projects that require rapid deployment on a compact footprint
