The [[CEB Press]] takes earth/dirt/soil and compresses it tightly to make solid blocks useful for building.  Compressed earth blocks have many advantages as a building material: by making the building materials from the readily available dirt on the building site, they eliminate the need to transport bricks from elsewhere, reducing the financial cost and environmental impact of transport.  Compressed earth blocks are very strong and insulate well against both heat and sound, making for very energy-efficient building (especially combined with the energy savings from not needing to transport them from offsite).  Best of all, the material they use is already on-site and does not need to be purchased -- quite literally, dirt-cheap!  See the wiki page on [[Compressed Earth Blocks]] and the [[:Category:CEB|CEB category]] for more details on building using CEBs.

Using the Liberator, two people can build a 6 foot high (1.83m) round wall, 20 feet (6.1m) in diameter, 1 foot (30cm) thick, in one 8 hour day, though construction time will vary somewhat depending on preparation time, what equipment is available (tractor to prepare the ground and move the blocks where they need to go), the quality of the soil, and other factors.  The bigger the block size, the faster a wall can be erected, but at the cost of heavier blocks that are more of a strain to work with.  Blocks from ''The Liberator'' average 25 pounds (11.3kg).

The [[CNC Torch Table|torch table]] will be used to automate the fabrication of the CEB machine, reducing fabrication time by an estimated 20 hours and, thus, the cost to build the machine.
 
==Components==
The Liberator consists of -<br>
*A '''[[CEB Press/Manufacturing Instructions/Hopper|Hopper]]''' at the top which you fill with loose dirt. This is made from welded steel. We made the hopper six feet wide, so it can hold a lot of dirt.
*'''Grate and grate shaker''' - the grate is at the bottom of the hopper. The grate shaker shakes it so that soil falls through into the compression chamber, while large stones and things like that are caught in the grate.
*A '''frame''' that bolts together for easy assembly and disassembly.
*A '''compression chamber''' where the bricks are actually pressed. This is a metal box with a nylon liner bolted on the inside. The liner gives the bricks a smoother finish. It will have to be replaced every hundred thousand bricks or so.
*'''Hydraulic cylinders''' - These are the muscles of the machine; they apply the pressure to the dirt. They are readily removable with pins. There are two hydraulic cylinders:
*The '''soil drawer''' - this moves from left to right and performs the dual function of loading soil into the compression chamber and ejecting blocks from the machine
*The '''main cylinder''', which moves up and down and compresses the blocks
*'''Tractor mount''', where an external hydraulic power source can be attached to the hydraulic cylinders.
*'''Pressure gauge''', which monitors the amount of pressure used by the hydraulic system to ensure a certain density of brick.
*'''[[CEB Press/Manufacturing Instructions/Controller Box|Controller Box]]''' controls the timing and sequence of operations.

CEB Press (aka "The Liberator")

Overview

Bricks pressed on The Liberator

The "Liberator" Compressed Earth Block Press is a machine that makes compressed earth blocks (CEBs).

Details

The CEB Press takes earth/dirt/soil and compresses it tightly to make solid blocks useful for building. Compressed earth blocks have many advantages as a building material: by making the building materials from the readily available dirt on the building site, they eliminate the need to transport bricks from elsewhere, reducing the financial cost and environmental impact of transport. Compressed earth blocks are very strong and insulate well against both heat and sound, making for very energy-efficient building (especially combined with the energy savings from not needing to transport them from offsite). Best of all, the material they use is already on-site and does not need to be purchased -- quite literally, dirt-cheap! See the wiki page on Compressed Earth Blocks and the CEB category for more details on building using CEBs.

The Liberator has been fully designed and tested by the Open Source Ecology team. Because the Liberator is an open source technology, you can freely download instructions to build your own from materials you can obtain yourself, or contact opensourceecology[at]gmail[dot]com to buy a kit or a finished machine.

Building a machine yourself might seem intimidating, but every step of the process is fully documented and the OSE community is available on our discussion forums if you need help, advice, or a little hand-holding.

Using the CEB Press, two people can build a 6 foot high (1.83m) round wall, 20 feet (6.1m) in diameter, 1 foot (30cm) thick, in one 8 hour day, though construction time will vary somewhat depending on preparation time, what equipment is available (tractor to prepare the ground and move the blocks where they need to go), the quality of the soil, and other factors. The bigger the block size, the faster a wall can be erected, but at the cost of heavier blocks that are more of a strain to work with. Blocks from The Liberator average 25 pounds (11.3kg).
