Operation

1. Working Principle
Core Mechanism: High-frequency bottom vibration combined with mechanical downward pressure from the upper mold. This process vibrates and compresses the mixture (cement, sand, and crushed stone or fly ash) into shape, expelling air to ensure a dense brick structure. The machine is equipped with wheels; after molding and demolding, it moves forward, leaving the bricks directly on the ground. This eliminates the need for PVC pallets—saving on costs—making it ideal for small-scale construction sites in Africa and Southeast Asia.
– Power: Dual vibration motors (bottom vibration and upper mold compression); some versions include a simple hydraulic system for lifting the mold.
– Molding Cycle: 40–50 seconds per mold.
– Power Rating: 1.5 kW (compatible with 220V/380V); total machine weight is approximately 200 kg, ensuring easy portability.
2.Complete Workflow (Cycle Steps)
1. Raw Material Mixing (Pre-process)
Cement, sand, aggregate (stone), and water are mixed in a mixer to create a uniform, moist concrete blend.
2. Material Loading
The mixed material is manually shoveled into the hopper at the top of the machine, which then feeds the material into the mold frame below.
3. Vibration & Compression Molding
The bottom vibration motor is activated; high-frequency vibration causes the material to settle, expel air, and fill the mold. Simultaneously, the upper mold head presses down on the material. Vibration continues for a set period to compact the mixture and form the shape of a hollow or solid brick.
4. Demolding (“Egg Laying”)
Vibration stops, and the upper mold assembly (including the mold frame) is lifted upward, leaving the brick on the ground.
5. Machine Repositioning
The machine moves forward by one brick position, clearing the newly formed brick. The brick remains intact on the ground, resembling a “laid egg.”
6. Reset & Next Cycle
The machine is positioned for the next run, the hopper is refilled, and the entire process repeats. 7. Natural Curing (Subsequent Stage)
The bricks are left in place to cure; they must not be disturbed during the initial stage. They require watering to maintain moisture for 7 to 28 days and must reach the required strength before they can be moved or put into use.
