Dispersing shafts and mixing shaft

Two balanced side dispersion shafts with adequate taper in the terminal part guarantee the elimination of vibrations during the most critical processing phases even at high speeds.

The dispersion tools supplied with the machine are of the toothed disc type with a quick-fixing system of dispersing shafts for easy replacement.

Anchor type shaft with scrapers

Independent central shaft of the anchor type with side and bottom scrapers in order to obtain a perfect cleaning of the inner surface of the tank and at the same time convey the processed product towards the dispersion / mixing impellers reducing production times.

Main transmission

Main electrical motors and speed reducer fixed to the mixers group complete with pulley-type transmission and belts with profiles and dimensions suitable for the installed power.

Two column structure

On the side of the mixers group there are two mobile columns coated with hard chrome, ground and wear resistant with technical solution that gives the machine a high strength even in the most critical phases of the production cycle, minimizing vibrations and increasing stability.
