E.S.A. produces a complete range of planetary type mixers with capacities ranging from 301 to 001. They principally comprise a flat-bottom, circular tank with an adjustable paddling tool that can be removed from the main shaft.

The power is transmitted from the engine by means of double belts and a well-dimensioned angle gear. The engine type and output is selected according to the capacity of each version, whereby either an electric motor or petrol engine can be supplied.

The 1001 version is fitted with castors, while the 2001 and 2501 versions have pneumatic wheels for transportation. The 3201 and 5001 versions are designed to facilitate tank feeding with the help of motorized equipment.

The discharge opening has a simple rotating flap, which is not waterproof, but can be provided as such for liquid mixing. The manufacturer also offers an extra-flat frame option to enable the mixer to be fixed on a platform in order to set up a mini-plant on a building or production site.

Operating the E.S.A. Malaxeurs

Feeding the 200 and 2501 versions of the CMDSELD mixers is done by shoveling the pulverized soil and then adding the stabilizer, if any, in order to obtain the best blending of soil and stabilizer. A wire mesh on the top of the mixer keeps out large lumps and prevents the workers from accidentally putting their hands into the tank.

Water is progressively sprinkled with a watering can during mixing, whereby the drop test has to be performed at intervals to determine the correct moisture content. When the mix is ready it is discharged by opening the flap, and collecting it in a wheelbarrow or - in the case of the larger versions - transporting it on a conveyor belt or by means of a proportioning hopper mounted on a fork-Uft elevator.
