How does a brick making machine work?

Okay, let’s take the most common hydraulic brick making machine as an example to explain in a simple and easy-to-understand way how the brick making machine operates.

Its working process is much like an "automated mold imprint" and can be divided into the following key steps:

Step 1: Prepare raw materials

Mix the raw materials for making bricks (such as cement, sand, gravel, fly ash, and even treated construction waste) in a certain proportion.

Add appropriate amount of water and stir to form a loose mixture with suitable humidity.

Step 2: Feeding

The mixed materials are accurately filled into the mold (mold box) of the brick making machine through a conveyor belt or automatic feeder.

Step Three: High Pressure Forming (the core step)

The upper pressure head drops rapidly and is pressed into the mold.

Huge hydraulic pressure (up to tens or even hundreds of tons) is exerted on the material from above, compressing it tightly within the mold.

Some machines will also vibrate from below or from the side at the same time. Through the dual effect of "pressure + vibration", the material will be distributed more evenly, the internal air will be discharged, and the bricks will become very dense.

This process determines the strength and density of the bricks.

Step 4: Demold

After the pressurization is completed, the upper pressure head rises.

The bottom tray or side walls of the mold will move upward, pushing the pressed bricks smoothly out of the mold.

Step 5: Remove the bricks

The automated manipulator or conveyor belt takes away the still soft "green brick" and neatly stacks it on the maintenance trolley.

At this point, the mold is reset and ready for the next cycle.

Step Six: Maintenance

The pressed "green bricks" are not strong enough and must be sent to the curing room.

By spraying water vapor or letting it sit for a few days under natural conditions, the cement in the brick will be fully hydrated and finally reach the designed hardness and become a qualified brick.

A brief summary of the running process:

Prepare materials → Fill the mold → High-pressure compaction → Push out the bricks → Stacking and curing

The entire process can be operated manually, but modern brick-making machines are basically automated and continuous operations, with very high efficiency, like a tireless "brick-printing machine".
