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 Pilot scale PMA is supplied with the mixing
bowl enclosed in a stainless steel base which also incorporates the operator
control station. Electrical equipment is installed in a separate sealed
enclosure mounted the machine base.
The PMA-Compact™
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.
New 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.
