Revision or repair by a service technician

Detailed testing of the system components as well as documented performance tests provide information regarding the necessary measures for revision or repair work. When exchanging spare parts, the NEA service technicians remove individual components and test them and, as required, replace them with higher-quality wear materials. A process which is implemented from all international locations using the same competence.

Tailor-Made Process Technology

Grinding systems are used over several decades and the mill requirements can change during the course of time. The reasons for this are improvement of machine efficiency, but also adaption to changed process parameters. As NEA Process Technology only exchanges the components which are crucial for the new process in such cases, considerable cost savings can be made when revamping as opposed to making new installations.
