- two supporting members 40 are provided which each extend on one side of the feed belt 7,
- the basic frame 1 is supported on either side by caterpillars 50, such that the mobile mixer installation can be moved into the transport condition.
- the granular material In order to mix a granular material, such as for example sand or gravel, with an admixture, such as lime or cement, possibly while adding water, in order to obtain a finished product, the granular material is loaded in the dosing device 4 and led from this dosing device 4 to the mixer 8 by the feed belt 7.
- the amount of - granular material which is led to the mixer 8 is hereby continuously measured by measuring the weight and the speed of movement of the granular material while it is being moved over the feed belt 7.
- the amount of granular material being fed to the mixer 8 per unit of time.
- a volumetric measurement of the amount of granular material being brought to the mixer is possible.
- an admixture from a first silo 5 is added to the granular material in the mixer 8 while the weight of this silo S is being measured almost continuously in order to determine the amount of admixture being fed to the mixer 8 per unit of time.
- the granular material and the admixture are continuously mixed ia the mixer 8 and, after having been mixed, the leave the mixer 8 via tlie outlet 13 as a finished product. This finished product is thus cast onto the delivery conveyor belt 20 and loaded for example in a lorry via the latter.
- additives can be added to the mixture in the mixer, such as for example plasticizing additives.
- the inclination of the mixer in relation to a horizontal plane can be adjusted in order to regulate the length of stay of me mixture in the inixer.
