The finest results - production of modern materials using cryogenic processes

A. Ebbecke Verfahrenstechnik AG refines products by means of cryogenic fine painting, classifying, spray-rigidizing and cryogenic mixing. Many materials are only effective as a fine powder. This applies in particular to plastics, rubber, elastomers, pharam excipients and organic food applications.

The individual processes are as varied as the products to be processed. Ebbecke Verfahrenstechnik offers a variety of different concepts to meet your requirements. Depending on the strength, hardness, elasticity and plasticity of the raw material, different degrees of fineness and fractions can be achieved through jet grinding, impact crushing, grinding, cutting, crushing and crushing. In cryogenic grinding and processing, the use of liquid nitrogen or carbon dioxide has a decisive influence on the end result.

Cryogenic grinding (also known as cryogenic milling) can be so simple: In cooperation with the company Air Liquide, Krefeld, A. Ebbecke Verfahrenstechnik AG has entered into a strategic partnership in the field of cryogenic grinding. Air Liquide ‘s globally unique cryogenic grinding technology center was relocated to our Schöneck site and supplemented by various systems from our company. The result is a unique competence center for cryogenic grinding technology and cryogenic processes.

In the Ebbecke drying process, we precisely control the moisture content of your powders and granulates – exactly according to your requirements. Using processes such as vacuum or spray drying, we remove moisture from surfaces, capillaries and even crystals.

We analyze, optimize, implement – and treat your recipes with absolute confidentiality. Because your product properties are your capital. Our job is to perfect them using innovative drying technologies – not to change them.

Versatile solutions for demanding materials and maximum precision

For the field of cryogenic grinding for many innovative products such as 3D printer powder, aerospace powder, cosmetics and organic products, a dedicated cryogenic processing center and cryogenic grinding center was built at the Schöneck site. This is equipped with a vacuumized ring line connected to a large liquid nitrogen tank equipped with an evaporator to produce cold nitrogen gas.

Up to 10 different systems can be connected in this cryogenic processing center. The range of cryogenic processing systems includes counter-rotating pin mills, wide chamber mills, cutting mills, Fitzmill systems, hammer mills, classifying systems, screening systems, cryogenic spray solidification and cryogenic mixing systems.

With a total volume of approx. 5,000 tons per year, we already process large quantities under cryogenic conditions. In addition to the cryogenic grinding center, we have a wide variety of large-scale cryogenic systems throughout the site on which the corresponding cryogenic processing can be carried out. The products are cooled down using both vortex screw coolers and nitrogen baths to ensure optimum preparation for further processing.

In line with the philosophy of A. Ebbecke Verfahrenstechnik AG, we use a wide range of different system makes in order to offer our customers the widest possible range of different makes and processes that are particularly suitable for their applications. Ask us if you require services in the field of cryogenic grinding or if you would like to utilize this area as an outsourcing component.

In the field of cryogenic micronizing, we have Hosokawa Alpine AFG 200 and AFG 400 opposed jet mills, impact grinding systems with Netzsch Condux CUM 300 stator-rotor and rotor-rotor systems as well as Pallmann and Hosokawa Alpine CW 250 wide chamber mills, UPZ 315 and UPZ 160, Gotic and Fitzmill mills, Jaeckering and Hosokawa Alpine classifier grinding systems and Netzsch Condux and Hosokawa Alpine hammer mills, cutting mills and classifier systems as well as Ebbecke’s proven in-house developments in jet milling technology, types ESM 170, ESM 450 and ESM 500.

Innovative products from the areas of 3D printer powder, battery chemicals, aviation, aerospace and defense in particular require particle sizes between 20 and 250 μm or between 50 and 180 μm. Sifting can be carried out using air classifiers, screening systems or ultrasonic fractionation. Cryogenic fine grinding processes with counter-rotating impact mills and jet mills are mainly used to produce innovative fine powders.

Classification is required after the grinding process to ensure that the often disturbing fines are removed.

For this purpose, Ebbecke Verfahrenstechnik has combination systems that ensure grinding (falling below the top grain range) and sifting in the downstream area. For this purpose, ultra-fine classifiers from Hosokawa Alpine and Netzsch Condux as well as in-house developments from A. Ebbecke Verfahrenstechnik AG and screening plants from Allgaier and J. Engelsmann, among others, are used.

The production of fine powders often requires the use of different process steps. In addition to cryogenic and non-cryogenic mixing, cryogenic grinding and sifting, packaging in special containers, Ebbecke Verfahrenstechnik also provides packaging, warehousing and logistics worldwide.

Organic products in particular, but also a large number of inorganic products that are required in high fineness ranges, are susceptible to melting of the surface due to the large surface area and thus the destruction of the desired grain structures. The result is a smearing of the products in the processing plant with clogging of the grinding units. These include oily and organic products as well as modern 3D printing technology materials such as TPU, EVA, PEEK, polyamide and others.
