Successful trade fair appearances in Dortmund and Moscow

These trade fairs are not to be missed. At the SOLIDS (‘Schüttgut’) trade show in Dortmund and Mining World Russia in Moscow we presented our products to a large trade audience and succeeded in making many promising contacts.

Our belt drums keep conveyor belts in motion – over long distances, inhospitable terrain and in challenging climatic conditions. They are robust, durable and run virtually seamlessly. All reasons that have been convincing a great many customers worldwide for decades.

Now we have had the opportunity to demonstrate our belt drums at two trade fairs almost simultaneously in front of an international trade audience. SOLIDS took place in May 2017 for the 8th time in Dortmund. This trade show has become the most important industry event for bulk solids technology and saw record numbers of visitors this year: over 6700 interested parties attended to learn about machines and new methods. Many of them also visited our stand. Jörg Amend, Head of Conveying and Mining Systems at Doppstadt Calbe GmbH, who represented us at the event, says: "For us this trade show is a must. This is where the industry decision-makers meet, where we make contacts and where contracts are initiated." An example of this is the new project enquiry by Fels-Werke GmbH, one of the largest producers of limestone products in Germany.

The outcome of Mining World Russia, held in Moscow, was equally pleasing. At this international trade show devoted to mining and metals and minerals processing in April 2017 we established numerous contacts with potential customers and also rekindled links with our existing customers in Russia. Jörg Amend reports: "There was great interest in Doppstadt from the trade audience and new sales partners far beyond our expectations." Initial enquiries are already coming in from the Uralkali mining company, which hopes to equip its machinery with new belt drums from Calbe.

With such positive results, it goes without saying that we have already booked our stands at both trade shows for next year.
