Vertical blender/dryers

ROSS Vertical blender/dryers designed for vacuum operation offer a better alternative to non-agitated dryers such as ovens and tray dryers, delivering significantly higher drying rates per unit heating area. Vertical blender/dryers can also handle a variety of feed forms including slurries and pastes which other types of agitated dryers cannot accommodate. Finally, the gentle mixing action supplied by a vertical blender/dryer minimizes product attrition which is a concern in some applications.

Agitated vs. non-agitated dryers

Agitated dryers give significantly higher drying rates per unit heating area than non-agitated systems such as ovens and tray dryers. This is due to continuous renewal of solids in contact with the dryer’s heated surfaces. In addition, the agitation improves uniformity of the product.

By contrast, due to long drying times, oven or tray drying operations are often allowed to proceed overnight which can impact energy costs and production rates.

The main issue with agitated dryers is the risk of product attrition or generation of too many “fines”. Also, some designs, such as rotary dryers or tumble blenders, can typically accommodate only free-flowing solids as feed material.

ROSS vertical blender/dryer

A vertical blender/dryer features a slow turning auger screw which orbits a conical vessel wall while it turns and gently lifts material upward. As materials reach the upper most level of the batch, they cascade slowly back down in regions opposite the moving auger screw. This blending action is almost always gentle enough even for the most delicate of applications, imparting significantly less shear than horizontally agitated systems, like ribbon or paddle-type blender/dryers.

Another advantage of the vertical blender/dryer is the wide range of feed forms that it can accommodate – from slurries, wet cakes and pastes, to granules, pellets and powders. Finally, vertical blender/dryers require a smaller footprint compared to other agitated dryer systems.

Benefits of vacuum drying

Requiring only low heat to drive off moisture or solvents, vacuum drying is an excellent method for drying heat-sensitive products without fear of thermal degradation. Drying is controlled and solvent recovery is efficient.

The application of a deep vacuum in combination with gentle heat and agitation in the vertical blender ensures short drying times. A liquid feed material, for example, will undergo a series of relatively swift changes in physical state – from slurry to a paste, and from a paste to a dry powder. Some applications such as plastics and specialty chemicals are commonly fed into the vertical blender already in solid form and may not look too different from the finished dried material.

Solvent recovery

A well-equipped vacuum drying system allows for solvent recovery. By condensing and capturing solvents, contamination of the atmosphere is prevented, both inside and outside the plant. They are then available for re-use or safely discarded to meet environmental requirements.

Wobbler Feeders

Wobbler feeders are designed for combined feeding and separating in any wet and sticky operation.

Used before primary crushers, wobbler feeders excel where others fail – in situations too wet and sticky for other feeders and scalpers. This is made possible by their self-cleaning and non-clogging elliptical bars, which allow material to be fed and separated without blinding.

High productivity

Able to feed and separate in one operation, wobbler feeders can actually double material production. The durable wobbler construction is designed to work at top efficiency under heaped loads.

The secret behind the wobbler feeder’s ability to handle wet, sticky or dry oversize material is in the original “Wobbler Feeder Principle”. The positive action of the rotating elliptical bars causes material to tumble forward assuring separation of fines and a uniform feed rate. This helps to greatly increase the capacity of the crusher or impactor being fed since material is delivered free of dirt and clay.

Versatile applications

For increased operational flexibility in your mining operations, wobbler feeders can be used for mineral processing, bulk loading and unloading terminals, as well as for in-pit and underground operations.

They operate with low horsepower and headroom requirements, and without vibration, noise or transmitted stresses, making them ideal for both stationary and portable applications. Depending on the application, they can be fed by an apron feeder or directly via trucks or loaders. They can also be used in secondary applications to separate already crushed feed material.

Low maintenance needs

Wobbler feeders are self-cleaning and designed to resist clogging and reduce blinding. They also feature an automatic lubrication system and a jog reverse function to quickly and easily solve any jamming situation.

Safe to operate

They operate without generating dust, vibration or loud noises for increased operator safety. Features such as the automatic lubrication system enable the feeders to work seamlessly for longer, reducing the need for operator intervention.

Drum Magnetic Separators

Bunting’s drum magnetic separators are self-cleaning, allowing for continuous removal of ferrous contaminants from a wide range of free-flowing bulk and granular materials in high-volume applications.

Drum magnets are designed to achieve magnetic separation in bulk materials and materials experiencing high flow rates. Bunting’s drum magnets and drum separators are self-cleaning, allowing for continuous removal of ferrous contaminants from a wide range of free-flowing bulk and granular materials in high-volume applications. Bunting manufactures many different varieties of drum separators, ranging from heavy duty electromagnetic drums that work to separate ferrous metals from non-ferrous metals, to permanent magnetic drums for fine iron separation.

When material flows onto a drum magnet, a stationary magnetic assembly inside the unit’s shell captures tramp metal, holding it securely to the drum’s stainless steel surface. With contaminants removed, the good product falls freely to a discharge point. As the drum rotates, cleats sweep the ferrous debris through and out of the magnetic field. The tramp metal is then discharged separately, creating a system of continuous self-cleaning magnetic separation.

The magnetic drum separator is normally installed at product discharge points, and is designed to incorporate a 150-180 degree magnet system. The design of Bunting drum magnets allows you to continuously clean your product without the need to stop operations or shut down product flow.

All drum magnets are available in electromagnetic or permanent designs, as well as including the option to be made with a high intensity rare earth magnetic system (ideal for separation of exceptionally small contaminant particles).

Combining feeding of materials with weighing

General applications include the feeding of dry bulk materials into a process. You may just need to confirm how much material you have received.

You might also need to know how much material you are feeding into a process so that you can closely control the downstream addition or blending of ingredients.

In a food processing application, this could involve adding seasonings and ingredients as well as drying of the product. This is important to control costs and product consistency. We all know what our favourite food tastes like and we will instantly reject something different or inferior.


Another reason to combine feeding of materials and weighing is to reduce the footprint of the equipment as you have only so much space. It is possible to add a weighing feature into a conveyor or bucket elevator. This can also reduce overall cost of equipment.
