Equipment Introduction
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.
Application in Clay Brick Plant:
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.

Function:
• 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.
Extrusion Advantages:
• 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).
Key Specifications:
• Extrusion pressure: 2.0-3.5 MPa
• Vacuum level: -0.08 MPa
• Capacity: 8,000-12,000 standard bricks/h
• Installed power: 45-75 kW
• Brick types: solid, perforated, hollow blocks
• Dimensions: approx. 4.5 m × 1.6 m × 1.8 m
This compact extrusion brick machine is most suitable for the following two types of scale of clay brick factories:
1. Small-to-medium brick plants (3,000-20,000 t of finished bricks per year, operating in one or two shifts).
2. Retrofit projects with limited building height or length, or emergency/short-term projects that require rapid deployment on a compact footprint.
