The 80 kg mixer has a frame consisting of a base and two vertical posts. The flat-bottom cylindrical tank is movable. It is housed in a casing containing the electrical heating resistances and an insulating layer of ceramic fibres.
This envelope swings around two horizontal pivots driven by a reducer ordered manually by a handwheel. The tank is topped by the mixing head consisting of a bell on which are fixed the electric gear motor and the epicycloidal gears that drive the Archimedes’ screw and the scraper blade. A door in the wall of the bell allows the addition of components during the mixing process.
A safety system interrupts the rotational movements when the door is opened. The whole mixing head slides along the vertical posts thanks to two chains driven by an electric gear motor.
Switches limit the up and down travel. A cabinet contains the electrical ordering and regulation devices. A 25 kg mixer with a very similar design also exists. Its principle is identical to that of the 80 kg mixer. Some changes have been made in the construction provisions
