Jetstream Mixer

Function

0 A fast rotating rotor creates a liquid stream in a stator

O Liquid stream its directed towards the bottom of the vessel

O No rotation of the liquid tn the

vessel - vertical mixing

O Liquid stream ts divided on the bottom of the vessel and directed upwards

O On top of the surface the liquid

stream Is redirected towards the

rotor-stator-system

O The whole contents of the vessel Is

moved completely

O micro mixing tn the mixing head

O macro mixing in the whole vessel

Batch Disperser

¬n the product ts forced

through a rotor-stator-

system

4 the inner rotor accelerates the product to maximum speed and the stator reduces

it to almost zero and then it

is again accelerated by the

next rotor ring

Q this results in a very effective particle size reduction by mechanical and

hydraulic forces

Inline Dispersing

O Reverse flow directions are

O The number of passages through

the rotor-stator-system,

the time for a passage through

the dispersing zone and ‘i

the pressure inside the

chamber can be controlled

QO Up to Viscosities of about 10.000

mPas In-Line dispersers can pump

themselves

O For higher viscosities additional

pumps are used

Inline Dispersing

For in-line processes we supply machines with:

O one ore three stages

0 each stage with different tools

O first stage with pumping tmpeller

The dispersion passes maximum 3 stages with

3 rotors + 3 stators

= 18 dispersing rings

in just one passage!

DispermIix

High mixing effect and simultaneous dispersing

Short processing times

No additional dispersing required Easy adaptation to different

processing procedures

Installation from top or as side entry

Lump free dispersion of gels and

high viscosity products

Ideal combination of homogenous Mixing and Dispersion

Production of Dispersions, Emulsions, Solutions

Fast Desagglomeration

No Reagglomeration

¥Ystral-Dispermix

Function

O A fast rotating rotor creates a vertical

liquid stream On the bottom of the

vessel the liquid ts divided into two

streams and Is forced to flow upwards

where it is again redirected towards

the bottom of the vessel

QO Aring at the lower part of the stator

forces a certain part of the liquid

stream to pass through the

rotor/stator system and causes a

particle size reduction by the

dispersing effect

Advantages

of any atr

homogeneously mixed and dispersed

simultaneously

4 Agglomerates are immediately broken,

no lumps can form

original particle size

Ystral High Shear-DispermIix

O For Applications with higher

shear requirements

O Complete Dispersing rotor

ring

O It combines the Jet stream

mixer with the Shearing

effect of a real High shear

Disperser

available

O In normal direction: mixing +

high shear

In reverse direction mixing

with almost no shear

ystral Dispermix

with cutting knifes

O Special rotor with cutting wings for breakup of bigger pieces

OQ Typical applications:

- melting of wax plates

- dispersing of frozen spinach

- Dissolving of big agglomerates

4 Melting and dispersing times are reduced extraordinary

OQ Machine ts designed for a

“heavy use”

Deformation - as happen very often with conventional stirrers

- do not arise

QO Multipurpose design:

The cutting Dispermix head can

be changed easily into a Jetstream mixing or a dispersing head for other applications in

future
