Description

The CERADES disintegrator has been especially developed to be used with a CERATEC manual or automatic press (ie a CERAMAN or CERAMATIC press) in the production of stabilized soil blocks or burnt clay bricks and tiles. The CERADES H2 is an impact rotor crusher consisting of two counterrotating hollow drums (squirrel cage type). The machine can be delivered in several versions with an electric motor or diesel enginge, and can include a 4m conveyor belt powered by the same engine.

The machine is used for the primary crushing mixing and homogenizing of raw soil of medium hardness (Mohs hardness 1 - 3), and with a moisture content ranging between 0 and 20%.

The working principle of the CERADES H2 excludes wear and tear, because there is no friction between the raw material and the mechanical parts.

Operating the CERADES

The CERADES is only used for the preparation of relatively dry clay or earth. The average natural moisture of earth before extraction is usually between 10 and l5 %, which is the ideal moisture content for disintegrating.

Only one person is required to feed the CERADES. After starting the engine, the earth is continuously shovelled into the machine from the top. Thus, if site conditions permit, the disintegrator should be positioned at a lower level than the earth pile, in order to reduce the effort needed to feed the machine.

For the production of stabilized soil blocks, the stabilizer (usually cement) has to be blended with the soil very well. This can be done by premixing the dry soil and stabilizer on the ground and adding a small amount of water to the mix, before feeding it to the disintegrator.

The outcoming mixture can be carried away manually, or automatically on a conveyor belt. Generally, the freshly disintegrated mix is ready for use in a brick press.
