The ErichHahn MB-25 | MB-50 unit is designed for the production of polymer-modified bitumen and ensures the production of all grades of PVB, PM, and PG bitumen in accordance with both domestic (GOST R 52056, GOST R 58400.1) and foreign (EN 14023) standards.
The capacity of the MB-25 ranges from 25 to 35 t/h, while the MB-50 has a capacity of 50 to 60 t/h.
The unit is designed using continuous (flow) production technology and is capable of meeting the highest customer requirements for the production of high-quality road material. The flow technology ensures maximum production flexibility. The modular design and modern equipment enable the installation to be quickly implemented both in the equipment of new facilities and in the modernization of existing production lines.
