Steady growth through the construction of more and more mineral mills. Grinding of lithium ores and zirconium oxide and recycling of refractory regenerates from the steel and glass industry

The 80s

The processing of refractory raw materials from China is becoming increasingly important. The proportion of recycled building materials continues to decline.

All processing plants are equipped with dryers, modern screening machines and ball mills. Furthermore, a mixing station is available to provide MgO masses to the steel industry. It takes about one and a half days for a barge to travel the distance of approx. 300 km from the seaports to Hamm.

The MMW has a total operating area of 70,000 m2,of which 50,000 m2are used for the storage of minerals, 20,000 m2 of the storage areas are covered.

TRANSPORT- ROUTES

FAST AND SAFE

ON LAND AND AT WATER

As we are located at the port of Hamm, the canal port in Europe with the highest turnover of goods, we have the ideal logistical connections to some of Europe’s most important seaports in Rotterdam, Antwerp and Amsterdam. Raw materials are delivered to us from all over the world using the Dutch waterway network: the Rhine, the Wesel-Datteln canal and the Datteln-Hamm canal.

It takes about one and a half days for a barge to travel the distance of approx. 300 km from the seaports to Hamm.

But we are also excellently accessible by road.
The Hamm mineral mill is conveniently located on the main arteries A1 and A2 for optimal connections in all four directions.
