agriculture high frequency screens
High frequency screens utilize high speed vibration, from 3000 RPM, directly induced to the screen media, allowing for increased stratification and material separation.
a device which separates a mix of particles into two or more groups
When screening is done, bulk material is separated into two or more products on the basis of either bigger than or smaller than a certain size

High Frequency Screens Specifications

Bulk material is separated into two or more products on the basis of either bigger than or smaller than a certain size hence the alternate term ‘size control’ for screening.

Screening Applications

Grain Sizing

Allows for precise separation of fine materials, typically down to 1 mm level for all grain cleaning needs

Grain Cleaning

Pre screening or scalping can be employed to remove the oversized material, after which the main screening deck will remove undersized material, leaving a perfectly sized product.

Adaptable Angles

Easily adaptable angles is employed to decrease or increase flow rates and ensuring ideal flow rate for maximum efficiency.

Interchangeable screens

Easily interchangeable wire mesh panels with various aperture configurations provide unmatched versatility and adaptability.

Mobile screens

Illustrating a design philosophy based on versatility

Grain Cleaning

Union Engineering now boasts a Grain Cleaning Division that builds two standard models of static screens and two standard models of mobile screens, ‘Sifting’ is discharged by means of an Auger designed to handle between 8 and 12 % of feed tons.

Easily interchangeable wire mesh panels with various aperture configurations provide unmatched versatility and adaptability, allowing the user to switch from maize to soybean to sunflower to wheat/oats to canola within an hour.

Using a ‘modular’ approach, the basic screen can be complimented with a pre cleaner to separate, for example, green soy pods from soybean seeds with an auger to discharge the green pods before the soybeans are discharged onto the actual screening decks for Sifting and a ‘load out’ auger can discharge the clean grain directly into waiting for trucks illustrating a design philosophy based on versatility, and minimum handling and storing of grain above all simplicity.

By combining the in house metal fabrication capacity with the output of the screening division. Union supports the capacity to retrofit the screens into existing silo complexes or even design ‘tailor made’ screens to add to existing storage facilities.
