CRYOGENIC GRINDING CENTER IN SCHÖNECK
THE FINEST RESULTS – PRODUCTION OF MODERN MATERIALS BY MEANS OF CRYOGENIC TECHNOLOGY
A. Ebbecke Verfahrenstechnik AG refines products by cryogenic fine grinding, classifying, spray solidification and cryogenic mixing. Many materials only show great effect as fine powder. This is especially true for plastics, rubber, elastomers, pharmaceutical excipients and organic food applications.
The individual processes are just as diversified 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 by jet grinding, impact crushing, trituration, cutting, breaking and pounding. In cryogenic grinding and processing, the use of liquid nitrogen or carbon dioxide has a decisive influence on the final result.
With relocation of Air Liquide’s globally unparalleled technical center for cryogenic milling to our facility in Schöneck, along with adding a variety of our own machines, A. Ebbecke Verfahrenstechnik AG and Air Liquide from Krefeld started collaborating in a strategic partnership. The result is a unique center of excellence for cryogenic milling technology and processes.
Cryogenic micronisation / Perfection in the field of cold grinding
Due to the large number of a total of 18 different processing lines with varying capacities, the company has a wide range of process technology at its disposal in order to use the most suitable processes for each specific product. Technical center machinery is available for sample quantities and preliminary tests. By combining technologically advanced technical centers with existing Ebbecke Verfahrenstechnik machinery, a one-of-akind range of production lines has come to be, that is unparalleled in its diversity.
Independent production line construction by ussing various brands
In the field of cryogenic micronizing we have at our disposal opposing Hosokawa Alpine jet mills , types AFG 200 and AFG 400, Netzsch Condux impact grinding systems with stator / rotor and rotor / rotor systems, type CUM 300 as well as Pallmann and Hosokawa Alpine, type CW 250 wide chamber mill, UPZ 315, UPZ 160, Gotic and Fitzmill mills, Jaeckering and Hosokawa Alpine classifier grinding machines and hammer mills, Netzsch Condux and Hosokawa Alpine granulators and classifier machines as well as the proven Ebbecke in-house developed spiral jet grinding technology, types ESM 170, ESM 450 and ESM 500.
Grinding and sifting in the same step
Especially the innovative products in the fields of 3D printer powder, battery chemicals, aerospace and defense require grain spectra between 20 and 250 μm or 50 to 180 μm. The sifting can be carried out by air classifiers, screening systems and ultrasonic fractionation. Innovative fine powders are mainly produced through cryogenic fine grinding processes with counter-rotating impact mills and jet mills. In order to ensure that the often-disturbing fines are removed, a classification is required after the grinding process.
Cryogenic fine grinding offers countless opportunities
For this purpose, Ebbecke Verfahrenstechnik utilizes combination plants, which ensure the grinding (falling below the upper grain size range) as well as downstream classifying. For this purpose, Hosokawa Alpine brand and Netzsch Condux as well as Ebbecke in-house developed ultra-fine classifiers and Allgaier and J. Engelsmann screening machinery are used.
Cryogenic processes by Ebbecke
The production of fine powders often requires the use of dif ferent process steps. Ebbecke Verfahrenstechnik guarantees not only cryogenic and non-cr yogenic mixing, cryogenic grinding and sifting, packaging in special containers, but also packaging, storage and logistics worldwide.
A. Ebbecke Verfahrenstechnik offers countless possibilities for cryogenic processing
Especially organic products but also a multitude of inorganic products, which are required in high fineness ranges, are prone to surface meltingdue to the large surface area and thus to the destruction of the desired grain structures. The consequence is a lubrication of the products occurring within the processing equipment with clogging of the grinding aggregates. In this context, oil-containing and organic products as well as modern materials used in 3D printing technology have to be mentioned, such as TPU, EVA, PEEK and polyamide, among others.
