Working Principle
The JZXD Series Single-Stage Vacuum Brick Extruder first crushes, mixes raw materials such as clay and gangue, and adds water to adjust them to an appropriate humidity, forming plastic materials. After the materials are transported to the barrel, they enter the vacuum chamber under the pushing and extrusion of the screw shaft to remove internal air, preventing the brick blanks from cracking during firing. The degassed materials are further kneaded by the screw shaft to form dense clay strips, which are then extruded into brick blanks of the set shape through the head mold. Finally, the brick blanks are cut by the blank-cutting device, completing the continuous production of brick blanks and providing high-quality blanks for subsequent firing.
Product Features
Efficiently removes air from materials, improves the density and strength of brick blanks, and reduces the rejection rate during firing.
Compatible with a variety of raw materials and can use industrial waste residues for production, meeting environmental protection requirements.
The key components are wear-resistant, effectively extending the service life of the equipment.
With a simple structure, it is easy to operate and maintain, and can quickly switch between brick types.
Suitable for small and medium brick factories; operates stably with low noise, balancing production efficiency and environmental performance.

Frequently Asked Questions (FAQ)
The JZK40/40-15 model has an output capacity of 8,000 to 11,000 pieces per hour, while the JZK45/45-15 model produces 10,000 to 13,000 pieces per hour (converted to standard solid bricks).
The extruders are compatible with a variety of raw materials, including clay and gangue. They can also utilize industrial waste residues, meeting modern environmental protection requirements.
The design efficiently removes internal air from the raw materials within the vacuum chamber. This process increases the density and strength of the brick blanks and prevents cracking during the firing stage.
