| Résumé : |
The Business Unit Grinding & Dispersing, one of three business units of the global NETZSCH Group, offers a comprehensive program for the many challenges in mechanical process engineering. Here the Business Unit is primarily involved in the areas of wet and dry grinding, mixing, dispersing, deaeration and classifying. The laboratory- and production-scale machines, as well as complete production lines, are used in almost ail areas of industry, such as the future-oriented nanotechnology sector, the production of ink, minerals or foods. The bundling of processing know-how, our extensive machine program, solutions for customer-specific problems and our global presence are unique and hence the strength of the business unit.
A crushing or dispersing process is required in the manufacture of many different products. For some applications with the goal of achieving deagglomeration, disaggregation or delamination, manufacturing technologies are often applied for which optimization is both desired and necessary. With the new OMEGA technology from NETZSCH-Feinmahltechnik GmbH, optimization is often possible for such applications in terms of power requirements, output and service Iife of the machine as well as ease of cleaning and operation.
The function of this machine is similar to that of a high-pressure homogenizer. Due to the unique modular construction of the dispersing unit, the essential difference is that the OMEGA operates with a maximum pressure of only 700 bar. Thus, compared to agitator bead mills or high-pressure homogenizers, a savings in specific energy of more than 50% can be achieved for some applications. |
