weco Magnum is the most revolutionary advancement in separator screen technology in the last decade.  Designed for increased strength, the patented Magnum screen has shown significantly improved screen life over traditional designs.

Field testing has demonstrated effective screen life increases from 1.5 to 5 times, with no catastrophic failures.  Advanced mesh fusion divides the screen into discrete zones, preventing propagation of most tears.  The mesh fusion also enhances flow rates by stiffening the screen surface, which improves solids conveying.  Available in 18 to 60 inch round and all sizes of rectangular and white water filter screens, the Magnum utilizes standard Sweco screen frames and FDA approved materials.
As part of Sweco's ATS (Advanced TechnologyScreen) development program, Magnum can also be custom configured to obtain the most effective performance for each application.  Balancing screen life, capacity and blinding (plugging) resistance, Magnum screens can be tailored to meet the objectives of the specific operation.
Magnum - the future of screening technology - available from Sweco today.



Provides continuous, precise screening of dry materials, especially in the finer particle sizes. Uses screen sizes from 200-400 mesh for efficient separation of particles ranging from 850-70 microns. Handles the most difficult materials, including electrostatic materials and particles that tend to agglomerate easily.

 

Sweco^® Vibro-Energy^® Grinding Mills are the most versatile line of mills available today for fast, low-cost particle size reduction to sub-micron range. Vibro-Energy grinding action achieves higher output per input horsepower; precise control of size and distribution. Product contamination from media and lining wear is virtually eliminated. Maintenance costs are low because of few moving parts and replaceable linings made of abrasion-resistant metal, ceramic or elastomers.

The Sweco Vibro-Energy Mill's unique vibratory motion, coupled with the use of cylindrical media, allows a dense packing of the media bed assuring maximum media surface contact and minimum void area when operated under a low energy condition. Feed materials as large as 300 microns can be reduced to sub-micron sizes.

In the high energy configuration, feed materials as large as twelve inch agglomerates have been successfully milled and solid particles of a half inch are being reduced to a d50 of 5 microns.

The low energy condition is reserved for wet milling whereas the higher energy mode can be used either wet or dry.

Micro-Lab Testing Services

Now it is possible to complete wet or dry milling tests in the Sweco Vibro-Energy Mill with as little as 20 ml of material. To test your material:

1. Request and submit our Laboratory Questionnaire.
2. We assign a test number and contact you for an appropriately sized sample.
3. You send us the sample along with the appropriate MSDS sheet.
4. Results are typically returned within 10 days of receipt of the PRE-APPROVED sample.
   All samples are returned along with any projections.

Typically, sample sizes will be 200 to 300 grams dry or 0.5 liters of slurry, but they can be between 20 ml and 1 liter. Results from these tests can be used to size production
equipment that will give you the desired results.

Up to five test chambers or mill jars can be processed at one time. Many customers submit Nalgene Jars pre-charged with material and media, advising milling time required. After testing, the jar can be returned with no evaluation by SWECO. We are able to use 125, 250, 500 and 1000 ml jars.

Pilot plant trials are also available. These tests typically require minimum sample size of 9.8 liters of liquid or 4.5 kg dry. Tests are normally completed within 30 days of receipt of the samples.
