CEB Press Intro/no

"Liberator" Komprimerte Jordklosser Pressen er en maskin som lager komprimerte jordklosser (CEBer). Den tar jord og presser den veldig hardt for å lage faste klosser som kan brukes til bygging. Komprimerte jordklosser har mange fordeler som byggemateriale: ved å lage byggemateriale fra grunnen av på stedet, eliminerer de behovet for å transportere det fra andre steder. Dette reduserer kostnadene og miljømessig innvirkning fra transport. Komprimerte jordklosser er veldig sterke og isolerer godt mot både varme og lyd. Dette gjør bygninger veldig energieffektive. Best av alt, det koster ikke noe å bruke jord. Se wikisiden på og  for flere detaljer om bygging med CEBer.

Liberator har blitt fullstendig designet og testet av Open Ecology laget. Du kan nå følge instruksjonene for å bygge din egen, eller kontakte oss hvis du vil kjøpe et sett eller en ferdig maskin.

Å bygge en maskin selv kan virke skummelt, men hvert eneste steg av prosessen er fullstendig dokumentert og OSE fellesskapet er tilgjengelig på våre diskusjonsforum hvis du trenger hjelp, råd, eller en hånd å holde i.

Med Liberator kan to personer bygge en 1.83 meter høy, rund vegg 6.1 meter i diameter 30 cm tykk, på en 8-timers dag - konstruksjonstiden er vil variere avhengig av andre faktorer: forberedelsestid, hvilket utstyr som er tilgjengelig (traktor osv.) og kvaliteten av jorden. Dess større klossestørrelsen er, dess fortere blir en vegg reist. Og, selvfølgelig, dess større klossestørrelse, dess tyngre blir klossen. Klosser fra The Liberator vil være gjennomsnitlig 11.3kg.

vil bli brukt for å automatisere fabrikeringen av CEB maskinen, hvilket vil redusere fabrikeringstid med et anslag på 20 timer og redusere kostnaden av det endelige produktet.

How does it work?
Loose dirt is loaded into the hopper at the top. This falls through to a chamber where a pair of hydraulic arms compress it and then eject it. This video shows how the machine works:

   

List of components
The purpose is to explain the design very simply so that when it is explained in detail later, it will be easier to understand'''

The Liberator consists of -
 * A 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 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.
 * A frame that bolts together for easy assembly and disassembly.
 * 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 - this is where an external hydraulic power source can be attached to the hydraulic cylinders.
 * Pressure gauge

Product Ecology

 * Rototiller to prepare the soil.
 * Power source such as LifeTrac.
 * Tractor to load the hopper (optional)

Specifications

 * Height: 6 foot 11 inches/ 210.82 cm
 * Machine lifetime goals: 1 million bricks before repairs; liner may be replaced every 100,000 bricks
 * Fabrication time requirement for optimized production: 3-5 days, about 20 hours of direct fabrication
 * Manual fabrication tooling requirements: drill press, welder, acetylene torch
 * Optimal fabrication tooling: XYZ table with torch, MIG welder, hoist
 * Material costs: $1000-1350
 * Cost for machine: you can build your own for $3-5k in parts, or buy a readymade one here for $8k

Advantages of The Liberator

 * Easy repair. The Liberator was designed to make maintenance as easy and infrequent as possible. The part that is most likely to need replacement is a rubber sheet from McMaster-Carr. The press is designed for disassembly, so if repairs are needed, the cost should be minimal. And unlike commercial machines, you have all the blueprints and sources for parts here, so there should be no difficulty repairing it.
 * Requires as little as 1 person to operate. The only control required is turning the machine on, and from that point one simply loads soil and unloads bricks. There is an alternative manual version for $500 less (Is that correct?)
 * Modular power source. The Liberator does not have its own power source; it is designed to be attached to an external power source. This is in line with the OSE principle of modularity; different tools can be run from the same power source, allowing the same tool to fulfill many functions flexibly. The power source could be the hydraulics from LifeTrac (our tractor any flexible source of machanical power), Power Cube, or any hydraulic power source with a capacity of 6 gallon per minute (22.71 liters per minute).
 * Large hopper. Compared to other CEB presses on the market, The Liberator has a very large hopper. We found with earlier editions that a small hopper requires constant loading and this slows down the construction process.
