Very few institutes and universities in Europe have in-depth expertise in granulation technology. Every year, the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) in Dresden offers basic and advanced courses for customers in the ceramics industry. The University of Sheffield stages the International Granulation Workshop every second year, which consists of a two-day Granulation Course followed by a three-day Granulation Conference. The Workshop was held for the 7th time on June 29th – July 3rd, 2015. As is the case at IKTS in Dresden, EIRICH mixers are part of the program in Sheffield.
EIRICH mixing granulators with capacities between 1 l and 3000 l have only one rotor tool. Larger machines have two. There is no need for the high-speed, high-wear choppers which are installed on plough share mixers. Depending on the application, the rotor can run at speed above 30 m/s. This makes it possible to generate high shear forces and quickly distribute the fluids. In a hybrid mixing process, the speed can vary depending on whether wet or drying mixing takes place prior to granulation. By running the process with different tools and at different speeds, grain size can be manipulated over a wide range. Granulate with PSD D50 between 100 μm and 5 mm can be produced depending on the material.
EIRICH helps users identify the cheapest/best operating conditions for the granulation process. Feasibility studies using customer materials can be carried out throughout the year at the Test Center in Hardheim and at EIRICH Group sites around the world.
