MANUFACTURE
3 CLOSED LINES BY GERMANY TECHNOLOGY
To exploit and produce optimally high-quality raw materials, Son Nam designed 03 closed production lines according to the most modern German technology. At the heart of the system, Son Nam applies ultra-fine ball mill technology and separation technology that can adjust the particle size as required. High quality products after crushing are bagged by automatic technology according to customer requirements.
The entire production line is controlled automatically at the control room with experienced human resources to improve the productivity of the whole system. This is the basis for Son Nam to save costs for customers and ensure the delivery schedule.
