Machine Description
The PMA™ High Shear
Mixer/Granulator is a multi-purpose processor suitable for high speed
dispersion of dry powders, aqueous or solvent granulations and effervescent
products.
The Development / Pilot scale PMA™ is supplied with the
mixing bowl enclosed in a stainless steel base which also incorporates the
operator control station.
All electrical equipment is installed in a separate sealed enclosure mounted
the machine base.

Process Description
The overall concept of the New
PMA-Compact™ stems from the common needs of consistent processing and ease of
operation and cleaning. The mixing bowl is therefore shaped to wet granulate
the widest range of products in a reproducible manner in respect of batch size,
density and flow characteristics. Its shallow, wide diameter bowl guarantees a
consistent product vortex and reduces any tendency towards product adhering to
bowl walls.
Product yields are further improved by the positioning of mixer blades close
to the bowl base. A typical 3 minute dry mix operation is followed by
introduction of a granulation fluid under pressure using a spraying unit.
A free-flowing granulate is produced after 3-5 minutes, and the granules are
then rapidly discharged.
Design features:
- Modified design, improving exterior appearance and cleanliness by replacing
the multiple maintenance access panels with one access door for all maintenance
procedures.
- Hinge mounted control cabinet to the rear of the machine allows easy access
to the controls and motor/gearbox assemblies for maintenance and servicing.
- Reduced weight of the machine improves mobility.
- Optional ATEX Approved Purged Control cabinet allows on-board location of
flameproof controls, making the unit suitable for location in a Zone 1 /21
area.
