First stop: Thyssenkrupp Industrial Solutions AG in Beckum
Today, we started the second day of our field trip of the Institute of Mineral Processing Machines at the Thyssenkrupp Industrial Solutions AG in Beckum. On-site, we received a brief introduction into the company’s R&D department for mineral processing by its head, Dr.-Ing. Falk Silbermann. He then reported on a new process, the so-called torrefaction, to roast biomass and biogenic waste – similar to the production of coffee – to make biochar by means of an energy self-sufficient process. To this end, wood pellets, straw and manufacturing waste (for instance from sugar production), green waste or organic waste, among other things, can be used.
During our tour of the R&D department’s technical center, we then learned how to test new raw materials for cement production on a pilot scale to ensure that the subsequently built aggregates and equipment perform perfectly for each and every customer in their respective application.

Both make use of wire mesh of the medium-sized family business Haver & Boecker OHG in Oelde, founded in 1887!
On Monday, 08 October, our group of students and staff of the Institute of Mineral Processing Machines (IAM) visited the wire weaving division – one of the two business units of Haver & Boecker – in Oelde. After arriving from Freiberg, we received a warm welcome during a joint lunch by the company’s managing partner, Mr. Walter Haver, as well as Mr. Michael Stichling – responsible for the field of industrial wire screens.
A short presentation on its history and the current product portfolio was followed by an interesting tour of the company. Starting with the delivery and inspection of the wires, we were shown the complete manufacturing process of the 3,600 different specifications of wire mesh products. Haver & Boecker’s wire weaving division – also known as “Die Drahtweber” – produces precision fabrics out of wires between 15 μm and 6.3 mm in diameter in Oelde. 15 μm – i.e. 0.015 mm – is a much thinner diameter than the one of a human hair, which has a diameter of 0.04 – 0.1 mm! No wonder that Mr. Stichling did not immediately find the end of the wire on the spool 😉 Continue reading “Day 1 of the IAM Rhineland field trip, or: What do gummy bears and microphones for hard rock singers have in common?”
