It is with deep sadness and a heavy heart that we bid farewell to our dear colleague and friend, René Theißen.

As a sales professional for Recycling technology, René was one of the central faces of our SPALECK team for our partners and customers. Especially in the English-speaking and American regions, he was an absolute team player and equally valued solution finder.

After his training at SPALECK, René established himself as a sought-after expert in the then textile machinery division in the early years of his career. His father, our former employee Franz-Josef Theißen, was always his role model. Just like him, René was not only at home professionally, but also as a friend to our customers in Asia.

He also faced the enormous health challenges of the past year in the same way. Always confident, always focused on the positive and with his incredibly big athlete’s heart. He was supported by the best team he could have wished for, his dear family.

Dear René, we will miss your calm and positive manner, your wit and charm very much. We will miss you very much as a great person. At the same time, we thank you for every single day of the past 20-plus years. We stand by your family at this difficult time and express our deepest sympathy and support.

In deep mourning

Your SPALECK Team

Frequently asked questions

The precise design of a tension-shaft screening machine is always tailored to the recycled material. Factors such as the composition of the input material, its moisture content, contaminants, throughput requirements, and the recycling goals associated with the input material form the basis for this. Working with you, we define screening sizes, purity requirements, and throughput rates, and use this information to configure the exact machine settings—from screening panels to amplitude and machine features such as the SPALECK FineSideCOVER (FSC) or our MultiDECK technology with a split push rod. Learn more here about our ModularDESIGN+ concept, which we use to find the optimal screening machine for your material. We’d be happy to test the respective recycling material together with you free of charge at the SPALECK TestCenter.

Precise screening of the fine fraction results in clearly defined particle sizes. For example, if the fine fraction ranging from 0 to 10 mm is reliably screened out, downstream sorting equipment—such as eddy current separators, NIR sorters, sensor sorters, and X-ray sorters—operates more reliably and efficiently as a result. In addition, the system’s cleaning requirements are reduced, and higher material purity levels can be achieved. You can see a good example of the benefits of a tensioned-shaft screen in the reference video on municipal solid waste processing at our Swedish customer Tekniska verken. The video demonstrates how a SPALECK tension-shaft screen reduces the load on the downstream eddy current sorters and NIR sorting processes. You can find all the details about the project here.

The service life of screening mats for Flip-Flow screening machines depends heavily on the recycled material, the Recycling process, and factors such as the abrasiveness of the material stream. In many recycling applications, very long service lives are possible. Thanks to our bolt-free, modular clamping system, individual screening mats can be replaced quickly and easily as needed. You can see how this works in the video on our landing page for tension-shaft screen machines. You can get a competitive quote for replacement screening mats through our spare parts service.
