MIKRONS� Twin Shaft Mixers
MIKRONS� Dual Shaft High Speed Disperser are
mixers that will disperse pastes far too heavy for single shaft
Speed Dispersers in excess of 300,000 centipoises. This MIKRONS�
dual mixer is a two machine in one combining the dispersing action
of a high speed shaft and disc impeller with the high shear action
of the heavy duty open impeller.
To increase the dispersion of high gloss coatings, and in many cases
eliminate the need for sand milling of fine grind finishes. This
machine has two high-speed shafts, each with variable speed and
four impellers - two on each shaft positioned to alternately overlap.
The shafts can be moved sideways so that the impellers are a few
inches apart or moved together so that the blades overlap (without
touching). In the open position the impellers create the greatest
batch circulation. In the closed position impellers produce greatly
increased dispersion action. While both high-speed shafts operate
in the same direction, when opposite sides of the blades overlap
they are moving in opposite directions. The effect on material being
dispersed is that the rim or the tip speed is doubled.
The advantages of the high-speed dual shaft disperser over the
single shaft model are many:
. Faster pigment loading.
. Less heat build-up.
. Better dispersion.
. Lower viscosity operation.
. Less air entrapment
