Centrifugal screening

Ebbecke Verfahrenstechnik offers high-quality contract screening with vibratory and rotary screening machines.

Centrifugal screening for screening greasy, oily and light products

Vibratory/rotary screening unit - the solution for greasy, oily and light products

Centrifugal screening for demanding products

The vibratory/rotary screening machine enables you to contract screen difficult-to-screen products that would clog up screen feeders. This applies in particular to greasy and oily products as well as products with very low bulk densities. For this purpose, an eddy current bed is generated by means of a vane mechanism rotating in half-sieve shells. Targeted vibration overlays on the outer screen cloth prevent the cloth from sticking together and thus ensure high-quality screening of even the most delicate products.

Gentle processing for sensitive and demanding products

Areas of application

Our processes are specially tailored to the requirements of sensitive materials. Soft products can be ground without increasing the temperature, so that their shape and properties remain unchanged. Oily or oiled products are sieved just as precisely as dry products, ensuring consistently high quality. The production of homogeneous grain structures ensures a uniform end product, while protective sieving reliably breaks up agglomerates. In addition, the fractionation of energy-sensitive products enables precise separation without impairing their physical or chemical properties. This ensures efficient, gentle and high-quality processing.

Frequently Asked Questions About Centrifugal Screening

What is centrifugal screening in industrial contract screening?

Centrifugal screening is a screening process for challenging bulk materials in which a rotating set of blades creates a vortex bed. This makes it possible to screen even greasy, oily, or very light products that would quickly clog conventional screen meshes.

For which products is vibration and rotary screening particularly suitable?

Vibration and rotary screening are particularly well-suited for products that are fatty, oily, soft, light, or sensitive to heat. This process enables precise separation without subjecting the product to unnecessary thermal or mechanical stress.

How does centrifugal screening prevent the screen mesh from clogging?

Centrifugal screening combines rotational motion with targeted vibration superposition. This motion keeps the product in motion, reduces buildup on the screen mesh, and enables consistent screening even with bulk materials that are difficult to process.

What mesh sizes are possible with centrifugal screening?

In centrifugal screening using vibrating and rotary screeners, mesh sizes ranging from approximately 75 to 10,000 µm are possible. This means the process can be used for both finer separation tasks and coarser fractionation.

Can centrifugal screening also break up agglomerates in powders?

Yes, centrifugal screening can help break up or remove agglomerates reliably during protective screening. This results in more homogeneous particle structures and a more uniform end product for further processing.
