Understanding Brick Making Machines: Core Technology and Processes
Before comparing models and prices, it’s crucial to grasp the fundamental technology. A máquina de fazer tijolos isn’t a magical box; it’s a sophisticated system designed to automate and enhance the age-old process of brick formation.
The Basic Principle of Brick Manufacturing
The core process, whether for clay or concrete bricks, follows a consistent sequence:
1. Mistura: Raw materials (like cement, sand, aggregate, or clay) are combined with water to achieve a homogeneous, workable mixture.
2. Moldagem: This mixture is fed into a mold cavity that defines the brick’s shape (solid, hollow, interlocking, etc.).
3. Compactação: Significant pressure is applied to the mixture within the mold. This compresses the material, removing air pockets and creating a dense, strong structural unit.
4. Cura/Secagem: The freshly formed, “green” brick is ejected and must gain strength. For concrete bricks, this involves a curing period with controlled moisture. For clay bricks, it involves drying and then firing in a kiln.
Componentes Principais de uma Máquina Típica
While designs vary, most machines share these essential parts:
* Hopper: The entry point where raw materials are loaded.
* Misturador: A chamber where materials and water are thoroughly blended (integrated in some models, separate in others).
* Mofo ou Morra: The heart of the machine. This interchangeable steel component defines the size, shape, and surface texture of the final brick.
* Sistema Hidráulico/Prensa: The power source that generates the immense force needed for compaction. This can be a hydraulic ram or a vibrational mechanism.
* Painel de Controle: Houses the electronics for operating the machine, from simple levers to advanced Programmable Logic Controller (PLC) touchscreens.
* Sistema de Paletes: In automatic machines, bricks are formed on pallets (steel plates) that convey them through the production line to a curing area.

* Weekly: Lubricate all moving parts as per the manual. Tighten bolts and fittings. Inspect molds for wear or damage.
* General: Use only recommended oils and greases. Keep a logbook for service intervals and any issues.
Quality Control: Testing Your Brick Output
Implement simple checks to ensure your bricks meet standards:
* Resistência à Compressão: The most critical test. Samples are crushed in a lab to determine their load-bearing capacity (measured in N/mm²).
* Absorção de Água: Weigh a dry brick, soak it for 24 hours, and weigh again. Lower absorption generally indicates better durability and frost resistance.
* Consistência Dimensional: Randomly sample bricks and measure their length, width, and height with calipers. Consistency is key for efficient bricklaying.
Sourcing Raw Materials and Mix Design Tips
- Sourcing: Partner with reliable aggregate and sand suppliers who can provide consistent grain size and quality. Test new material batches before full-scale production.
- Dosagem de Concreto: While specific ratios depend on your desired brick strength, a common starting point for a standard concrete block is a 1:6:4 ratio (Cement: Sand: Aggregate). Always conduct trial batches. The right water content is crucial—too much weakens the brick, too little causes poor compaction.
