Vibratory Deck Separation for Flexible Finishing Operations
FMMS Series separators use vibrating screen surfaces to separate finished components from tumbling media. Their portable configurations can be positioned near finishing equipment to reduce manual handling and support efficient material flow.
Models and screen configurations can be selected according to the required separating area, part and media geometry, production layout, and desired capacity. A secondary deck can also be incorporated on applicable configurations to remove small or worn media during the separation process.
FMMS V3472 Configuration

The FMMS V3472 provides a large, mobile screen deck for separating finished parts from tumbling media. It can operate as a standalone unit or be integrated into a more automated finishing process.
Key Features:
- 34 x 72 in. screen deck
- Independent dual-motor vibratory drive
- Caster-mounted mobile frame
- Customizable polypropylene screen
- Optional water-assisted discharge for flat components
- Optional undersized-media separation
Standard FMMS-80 Configuration
The standard FMMS-80 configuration provides a mobile solution for separating finished parts from tumbling media. Its flow-through design can be positioned at the discharge of a vibratory finishing machine to reduce manual handling and keep material moving through the finishing process.
