Types of Blenders
|
|
|
|
|
Advantages |
- Cost savings as the thermal treatment is accomplished
in the same time and vessel being used for mixing
step
- Accurate control of batch thermal treatment time
- Good control of end material temperature
|
|
|
Atmospheric Mixers
(Dryers) |
|
Conductive
heating of materials through a thermal fluid jacket on
the mixing vessel will result in a flash evaporation of
volatile components such as water or organic solvents
as the material agitation or transfer exposes the material
to the open space at the top of the mixer. In order to
continue to drive the evaporation, the vapor in this free
space must be removed either by the assistance of a conventional
fan or by convection. |
|
Advantages: |
|
- Low capital cost as the drying is accomplished in
the same time and vessel being used for transferring
and/or mixing
- Control of batch drying time
- Good control of end material temperature
- Suitable for drying of either water or organic solvents
- No or low dust generation, reduces chances for dust
explosions that can occur in convective type dryers
- Residence time can be adjusted to allow for the
removal of "bound" moisture

Vacuum
Mixers |
Similar
to atmospheric drying, the vacuum process also reduces
the atmospheric pressure within the mixer to reduce the
vapor pressure of the water. This allows the evaporation
of the volatile component to occur at a lower temperature
than at atmospheric conditions. Based on standard models,
our engineers can design a vacuum mixer/dryer to your
specific processing needs. |
|
Advantages: |
- Lower operating temperatures make it more suitable
for heat sensitive materials such as pharmaceuticals
or materials that melt at higher temperatures at atmospheric
pressure
- Head space in the mixer is filled with vapor that
will reduce or eliminate presence of oxygen for oxygen
sensitive materials or solvents
- Batch drying time is infinitely variable depending
on the residence time required

Dust
Control Pug Mill |
|
These
pug mills are widely used for removing dust, the dust
material is fed into the mill and the mill is provided
with spray nozzles through which water is added to the
mill.The dust get mixed with water and the slurry is disposed
off. |
|
Generally
twin shaft pug mills driven with dual motor arrangemnt
is used.Available in 25, 50 and 100 TPH model. |
