Abstract The invention relates to a transportable mixer consist- ing of a double bottomed load body 3 for a change-load vehicle with the space between the bottom divided into longi- tudinal compartments and with an upper bottom consisting of a screen plate. To each compartment 11, 12, 13 via a switching mechanism 20, there is connected a hose 14, 15, 16, 21, 22 to a pump 23. After water is added, the com- partments are subjected with the aid of the switching mechanism to alternating pressure and suction, whereby the material loaded into the body is slurried from below and can be pumped out 24, 25 to the desired location. The screen plate retains coarser contaminants, stones, sticks etc. The load body can float and be towed on lakes, but can also be made in the form of a boat with a pump, switching mechanism and its own motor for driving and mixing. The body can be used to make use of old deposits of lime sludge for liming of lakes and soil, for industrial use of fly ash and similar waste materials etc. In an alternative embodiment, instead of the compart- ments and screen bottoms, two pipes are arranged at the sides of the load body, each with an opening covered by a screen plate. There is also arranged on the vehicle an articulated arm provided with a bucket a blade or a stirrer for mechanic- ally working the mixer, and a nozzle for spraying out the slurry, for distribution or for taking in water. By means of the switching mechanism and the pump, the slurry can then be sucked through the tubes and spread out in the body in order to activate the mixture, or can be sprayed out for distribution simultaneous with the mechanical working.
