Features & Benefits
Our MR Series Gyra-Vib® Separators are used to separate particles by size or separate solids from liquids. Designed for maximum screening efficiency and easy handling, Midwestern’s separation equipment can be constructed and finished to industrial, food, dairy, and pharmaceutical standards.
The MR Series Vibratory Separator features a conventional design utilizing a center-mounted motor and unique weight system to control the vibratory screening motion during the screening process. Easy change of the lead angle of the weights provides for optimal flow patterns and top performance.
Sifting, scalping, classifying, and dewatering applications benefit from the versatility and range of screening products available to customize each vibratory separator for specific end results. Multiple screening decks are available for simultaneous separation.
- Screeners range in size from 18 to 60 inches
- Fully customizable to meet your specific screening needs
- Multiple screening decks and accessories available
- Wide range of screen meshes down to 25 microns
- Perfect for both wet and dry applications
Distinct design features, such as the option to bolt the lower frames to the table assembly, and exceptional balance cages can extend screen life and ensure the longevity of each vibratory screener.

The Vibratory Separator is a cost-effective solution to your screening process. Each round separator is built individually to suit your screening needs. Whether it’s ultrafine powders or liquid/solid separation, the MR Series Round Separator can produce the results you’re after.

Description of Components
- Available with specially designed 1200 RPM motors. High-speed 1800 RPM motors are also available for applications that require screening solids from a large volume of heavy, high-viscosity liquids.
- Bolt-mounted lower frames will not turn and wear out the flanges on the table and lower frame. A conversion kit is available to modify an existing conventional clamp-mounted separator lower frame to the bolt-mounted style.
- Balance cages, designed for quick weight adjustments, can be mounted directly on the motor shaft.
- Reversible center locking devices allow positive screen tensioning, up or down.
