Product Description:
The double stage vacuum extruder for brick factories is the core forming equipment in sintered brick production lines. Specifically designed for the characteristics of various brick-making raw materials, it integrates raw material kneading, powerful mixing, vacuum degassing, and high-pressure extrusion. The equipment can efficiently process various brick-making raw materials such as clay, shale, coal gangue, fly ash, and construction waste. Through precise processes, it extrudes the raw materials into dense, smooth, and high-strength clay strips, providing high-quality blanks for subsequent processes such as cutting, stacking, drying, and firing. It is a key piece of equipment for modern brick factories to achieve automated, large-scale, and high-quality production, reduce scrap rates, and increase capacity.
Features:
1. **Dual-Stage Split Design:** Utilizing a split structure with an upper-stage mixing chamber and a lower-stage extrusion chamber, the processes are clearly defined and highly efficient. The upper-stage high-powered mixing chamber is responsible for humidifying, crushing, uniformly mixing, and fully maturing the raw materials, effectively breaking up lumps, activating their plasticity, and ensuring uniform moisture content and a fine texture. The lower-stage vacuum extrusion chamber focuses on vacuum degassing and high-pressure extrusion, with these dual processes guaranteeing molding quality.
2. **High-Vacuum Degassing System:** Featuring a built-in large vacuum chamber with a vacuum level of -0.08 to -0.095 MPa, this system thoroughly removes air from the clay, fundamentally solving common problems such as brick delamination, bubbles, and cracking, significantly improving brick density and yield.
3. **Wear-Resistant Core Components:** Wear parts such as the spiral auger, mixing blades, and liners are crafted from carefully selected high-wear-resistant alloy materials. These components are wear-resistant, pressure-resistant, provide strong thrust, and have a long service life, making them suitable for the harsh production conditions of brick factories with high dust and heavy loads, reducing the frequency of replacement and maintenance costs.
4. Sturdy Machine Structure: The entire machine is welded from heavy-duty steel, ensuring a stable and shock-resistant structure with strong load-bearing capacity. It is resistant to deformation under long-term heavy loads, ensuring smooth operation, low noise, and a low failure rate.
5. Intelligent Electrical Control System: Equipped with variable frequency speed control, one-button start/stop, overload protection, and fault self-diagnosis functions, the system is simple and easy to operate, allowing ordinary workers to quickly learn how to use it. It allows for precise adjustment of the output speed, flexibly adapting to different production capacity needs and ensuring safe and stable production.
6. Flexible Mold Changing Design: The machine head mold is easy to disassemble and assemble, allowing for quick switching between different brick specifications, achieving multi-purpose functionality and meeting the production needs of various products such as standard bricks, perforated bricks, and hollow bricks.

Applications:
Suitable for various sintered brick production lines, it can produce a variety of products such as standard bricks, perforated bricks, hollow bricks, paving bricks, and thermal insulation blocks; it is compatible with various brick-making raw materials such as clay, shale, coal gangue, fly ash, and construction waste; it is widely used in the supporting facilities of newly built automated brick factories and the upgrading and renovation of equipment in old brick factories, and is compatible with single-firing and double-firing processes. It is an indispensable core molding equipment for modern environmentally friendly brick production lines.
Working Principle:
After being processed by the front-end feeding and crushing equipment, the raw materials for brick making are sent to the upper mixing chamber of the double stage vacuum extruder. There, the materials are vigorously kneaded and mixed by the mixing blades, and then humidified and matured. The raw materials are then transported to the lower vacuum chamber, where the vacuum system completely removes internal air bubbles. A stable extrusion pressure of 2.5 to 4.0 MPa is applied by a high-pressure spiral auger to extrude the clay through the die head mold, forming it into regular and smooth clay strips. Finally, the strips are transported to the brick cutting process, laying the foundation for subsequent production.
