ALTECH soil mixers[edit | edit source]
Description
The ALTECH Soil Mixers, which are available in two sizes (with total/practical capacities o 250/180 and 320/240 litres respectively) are adaptations of cement mortar mixers, modified, to suit the specific characteristics of soil mixes.
The planetary type mixers have steel tanks wit vertical walls and two-paddle rotary tool. which can be removed quite easily from the main shaft. The adjustable wear blades have been designed to achieve a good mix and to prevent the formation of lumps or crust on the tank wall.
The power is transmitted from an electric motor (380 V / 3-phase, 7.5 hp and 10 hp respectively or petrol engine (8.5 hp and 12 hp respective!, by means of double belts. The larger mixer can also be supplied with a 12 hp diesel engine.
The ALTECH mixers are fitted with wheels facilitate transportation and movement on the production site, but they are also designed to to integrated in a CEB production line.
Operating the ALTECH Soil Mixer
On a common production site, the mixer is either wheeled near to the pile of sold or close to the press, but if the mixer (usually the 320 l version) is integrated in a production line with a motorized press, it is best to raise it on a platform just above the press, so that the mix can be fed directly into the press. Before operation, the machine must be set up on its telescopic legs.
When the engine has reached its normal speed, a measured proportion of soil is introduced (either by means of shovels or with the help of a conveyor belt from the soil pile or the soil disintegrator). The stabilizer should be added to the dry material. Once a uniform dry mix is achieved, water is gradually added. When the flap is opened, the final mix is discharged through a hole in the bottom of the mixer into a wheelbarrow or into the proportioning hopper of the block press.
Training
ALTECH offers to conduct training courses according to the users' requirements. The courses cover all practical aspects of CEB production, and the use and maintenance of equipment.
