Semi Automatic Graco Ram

Changing the inserts in the mold of the press, the bricks can be manufactured as shown on the right.


See types of bricks and their use.


The Lego bricks have bumps and holes on its faces for easy installation, avoiding the use of mortar for their union, only the application of a slurry of lime with cement or a industrial adhesive as used for Wood, the walls allow a building strong


See: Interlocking construction system


With the material ready, you can make two bricks by pressed every 12 seconds.


The inserts can be purchased individually, which makes, most economic the press machine



The standard measures of adobes are 30x15x10cm.
Other common measures of adobes are 40x20x10cm but the press can make only one adobe by pressed.
With suitable materials and proper stabilization you can get resistances  between 200 and 600 psi (1.4 to 4.2 MPa)

Economize building with Lego bricks:

· 90% Saving in cement

· 60% Savings in construction time.

· 50% Savings in labor.

· Total savings over 45%

Semiautomatic press for compressed earth blocks, it has the versatility to manufacture various types of bricks , which facilitates the ecologic houses construction.

The soil-cement technology that is used for the manufacture of bricks was developed in Colombia during the 50s of last century to be used by people with minimal schooling (reading and writing), no advanced knowledge is required.


You can buy  the machine with electric motor 7 HP 220 Volt single or three phase with gasoline or diesel engine for mobile plants.
We can also manufacture a trailer to transport the hydraulic press or the hammer mill and the mixer at the same time.

We can send this and all our machines to anywhere in the world, ask for a shipping quote.
The weight of the machine for shipment is between 800 and 850 kg depending on the inserts that you choice.
