Sturtevant air classifiers balance the physical principles of centrifugal force, drag force and gravity to generate a high-precision method of classifying particles according to size or density. For dry materials of 100 mesh and smaller, air classification provides the most effective and efficient means for separating a product from a feed stream for dedusting, or for increasing productivity when used in conjunction with grinding equipment. All three Sturtevant air classifiers offer durable construction, as well as time- and energy-saving advantages.

The Atritor DCM Mill is one of the most universal milling systems available with independently driven grinding and classifying sections.
It has a wide range of applications producing materials in some instances to less than 15 microns.
Feed material is metered into the mill pneumatically and first passes into the classifier zone where any fraction of the feed that is already inside specification is removed as product, thus avoiding any over-grinding. Oversize is recycled internally to the grinding zone and is returned to the classifier after further size reduction. This process produces a steep size distribution curve.
Adjustment of the classifier speed controls the size of the product leaving the mill. The product is conveyed pneumatically to a collecting cyclone and/or bag filter. With the application of heat to the inlet air flow, simultaneous drying can be undertaken.

Sweco's PharmASep is a fully contained Vibro-Energy Filter/Dryer suitable for aseptic processes in the pharmaceutical industry. With a design that eliminates gaps, crevices and hidden areas, the PharmASep proves valuable to those processes handling potent and/or toxic substances where containment is an important issue.
The PharmASep allows batch processing of up to 15kg of solids as well as continuous processing in pilot plants and full production environments. For both wet and dry processes, the sealed pressure vessel delivers high yield product recovery while containing potent pharmaceuticals for safer handling. Unique Vibro-DryTM Technology, developed by Sweco, allows vacuum drying to occur within the PharmASep while the product is gently tumbled on the screen surface, accelerating the drying process and reducing formation of agglomerates.
The PharmASep, with clean-in-place and steam-in-place capabilities, enables users to properly clean the machine without the need to disassemble and re-assemble, reducing downtime and ultimately increasing productivity. In the case of wet sieving, the PharmASep can dewater the product on the screen, apply vacuum, dry and discharge the dried product, eliminating the necessity for separate vacuum drying.

TURBOWEST
Turbowest centrifugal sifter
Vibrowest centrifugal sifter “Turbowest” is designed to provide users with an efficient dust tight high throughput sieving machine.
The equipement is versatile, economical and used for screening a wide variety of dry or moist materials, powders or granular products, including chemicals, plastics and resins, foods, dairy products, pharmaceuticals and biologicals.
It is especially suitable for high volume sieving, lumpy, sticky and dusty products, as the unit delumps and deagglomerates while screening.
Material fed into the inlet port of the unit passes into the infeed compartment and then, via a screw feed, into the sieving area. The sieving area consists of a mesh cylinder and a paddle blade arrangement revolving within. The centrifugal force propel the material through the full-length cylindrical pre-screen and screen surface. Coarse product is ejected at the end of the machine and the fine discharges through the base of the main body.
Product is sieved on a continuous basis and very large quantities can be processed very quickly.
Units may be free-standing or adapted for easy mounting on new or existing process equipment. All models have a large access door that allows inspection and cleaning.
The separator can be built on customer request with carbon steel, stainless steel AISI 304, stainless steel AISI 316.

Drum screener are used for the continuous separation of streamers respectively bird nests from plastic pellets. With the use of drum screeners downstream handling systems, problems caused by streamers and bird nests can be avoided.
Function
The rotating drum screener is gravimetrically fed with the plastic pellets containing streamers respectively bird nests. Due to the mesh size of the screener, the plastic pellets pass through the screener whereas the streamer and bird nests are retained. The streamers are trans-ported to the streamer discharge by rotation of the drum and a directional gas flow.
Design features
- reliable separation of streamers and bird nests from plastic pellets
- suitable for continuous operation due to automatic cleaning of the screener
- screen may be buffed or electropolished
- use in different operation modes (pressure, suction and circulation mode)
- easy disassembly of the drum screener
- quick-release openings for inspection and cleaning
- individual design for product requirements and throughput

Specifically designed for sifting of dry particulate, the Sweco GyraMax™ Gyratory Sifter maximizes productivity, provides maximum vibration control and enables maximum recovery of clean, acceptable product.
Maximum Productivity
The drive unit is designed into the center of the machine to get the same screening efficiency over the entire screen surface. With dynamic balancing and no mechanical gearboxes, screens operate at 300 rpm versus most conventional 150 - 180 rpm screeners. The consistent motion across the screen combined with the high speed make our ball box cleaning very efficient. The result is maximum efficiency and maximum capacity for your application with no downtime for cleaning screens. Additionally, productivity can be maximized by minimizing your downtime. The GyraMax offers quick and efficient screen changing through easy screen removal without disassembling your machine.
Maximum Vibration Control
All screens are dynamically balanced, allowing you to put the screen at the top of your plant, without worrying about building vibration. Without anchoring, every machine is factory tested to assure the balance meets our rigid standards.

Sweco manufactures several different rectangulars to meet all of your separation needs: the V3 which offers both linear and elliptical motion for wet processing of highly viscous materials; the Round Motion which is perfect for both wet and dry processes; the Universal Motion which offers round, linear, elliptical, and balanced motions; the Multi-Motion which was engineered specifically for liquid/solid separation; and finally the Gyramax which maximizes productivity, provides maximum vibration control, and enables maximum recovery of clean acceptable product.
The most common elements of downtime have been engineered out of the Sweco rectangular, providing a nonstop operation. New technology adapts ultra-fine screen mesh for use in rectangular high-capacity separators (36 ft.2), yielding benefits previously found only on small circular screens. Fine-mesh screen panels can be installed in five minutes without tools on some models. Our simple patented drive mechanism has 3 motors rather than a complicated and expensive 3 shaft design. Sweco rectangulars are capable of high G-forces for improved solids conveyance and are easily adaptable to Clean in Place spraying systems.
Other features of Sweco rectangular separators include an "off-the-shelf" motor which provides reliable power; isolated mount suspension that virtually eliminates transmitted vibration; and a rear basket feed inlet with an internal baffle system that uniformly distributes flow to the screen bed. Additionally, to maximize the effectiveness of your system, the deck angles on Sweco rectangulars are adjustable, eliminating the loss of good material due to process changes.
