Pilot scale high shear granulator
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.
