Vibratory Screeners
Vibratory screeners are versatile and efficient devices used for separating and sorting particles of different sizes and shapes. ABM employs vibratories in a variety of industries including food, dairy, chemical, pharmaceutical, and nutraceutical to name a few. Each OEM has their place in the market, and ABM will provide various makes depending on your application.
Typical screeners are available as flow-throughs or sorters up to 5 decks tall. They are available in any diameter between 18 and 100", though the most common are 18", 24", 30", 40", 48", 60", and 72". We provide them in any configuration including sanitary, gap-free, lift-assist, CIP, ultrasonic, flood-able, and custom mods. To skip the thinking give us a call to get the best solution for your project.
Operating Principle
Vibratory screeners fluidize product over screens so that only particles of a certain size pass. They have 1-5 levels of descending mesh size, discharging the particles that are captured at each layer and passing the smaller particles through the screens for further sorting. We also provide check-screeners with one mesh size and no discharge to capture contaminants. Screens are readily available with perforations of every size, spacing, and shape, but custom configurations are available as well.
Ultrasonics
Ultrasonics—high-frequency vibrations in the mesh itself as well as the housing—improves the flow rate and reduces blinding. Ultrasonics are available for most screeners and improve use of the screen area by reducing friction between the material and the screen, and can therefore be used to increase throughput without getting larger units. Most manufacturers get crude ultrasonics from China, which results in them being less effective and more difficult to maintain. For this reason, if you anticipate needing them, we only recommend Russell Finex, whose designs are more effective and who manufacture their "Vibrasonics" in the UK and keep inventory here in the US.
Types
Circular Vibratory Screeners
This type of screener is the most widely used and is easiest to clean, makes best use of screen's surface area, and produces the most consistent end-product.
Linear (Rectangular) Vibratory Screeners
This type of screener is used for fine screening of materials and is equipped with a linear screen that vibrates in a straight line motion. The linear motion of the screen allows for precise separation and sorting of the material into different sizes.
Gyratory Vibratory Screeners
This type of screener is used for high-volume screening of materials that do not respond well to the consistency or relatively low force enacted by vibratory motors. The imbalanced weighting subjects bearings to extreme load, an issue we help alleviate by continuously pressure-feeding them with lubricate.
Benefits
- Efficient: Vibratory screeners are very efficient for sifting when gravity is enough. The oscillating motors also have come to require less energy and smaller units can run on standard power.
- Versatile: Vibratory screeners can be used to screen a wide range of materials, including powders, granules, and liquids, making them popular in a wide variety of industries.
- Low Maintenance: Vibratory screeners are relatively simple pieces of equipment and require reduced upkeep and maintenance, reducing downtime and increasing productivity. We offer preventative maintenance programs to reduce total cost of ownership.
- Cost-Effective: Vibratory screeners have lower upfront costs than other screening methods.
When To Use
Vibratory screeners are best for separating or sorting materials of different sizes and densities when gravity is enough. We commonly integrate vibratory screeners into:
- Bulk bag unloaders - to sift material or ensure the process is receiving ingredients of a certain fineness
- Milling systems - to return large particles for a second pass to the mill
- Dewatering lines - to remove liquids from solids when budget is a big concern
- Classifying systems - to separate product when it's being sold or used by size
When Not To Use
Vibratory screeners are not effective for screening materials that need extremely fine classification, have very low density, or which are sticky. All of these properties are problematic because the only force pulling product through the screen is gravity, which is obviously fixed. When greater force is required, air classifiers or centrifugal sifters will be preferable.
Additionally, vibratory screeners may not be suitable for applications where the material being screened is sensitive to mechanical stress and can break even with vibration. In these cases, alternative screening methods—such as pressure or static sieves—may be more appropriate.
