Tender Details

The F.A. Finger Institute for Building Materials Science at the Bauhaus University Weimar is planning to purchase a continuously operating dry grinding and classifying system consisting of an agitator ball mill (RWKM) with a downstream air classifier and the associated equipment Conveying, dust removal, measuring, control and safety devices. The system should be designed for research and development tasks. The system is intended for the mechanical activation of mineral raw materials, preferably clays and olivine, as well as for for the fine grinding of mineral or comparable dry solids. The classifier should have the task of classifying the product stream and, if necessary, returning product to the grinding circuit, as well as certain grain fractions separate for investigation purposes. The mill will also be used to carry out experiments on agglomerating fine powders, which will help improve the processing properties of the products. That's why the sifter has to be as easy to open as possible Dedusting operation (or inverse) can be changed. The classifier must also be able to be operated separately without a mill. The system should be suitable for product throughputs of 100 kg for research purposes up to several tons (per week). to cope with industry-related research. The mill must be designed in such a way that wearing parts can be easily replaced and must be easy to clean. The grinding chamber volume should be between 30 and 60 liters. The grinding room as well as all Mechanically stressed parts must be made of highly wear-resistant steel. The RWKM and the relevant classifier system must be scalable, i.e. performance data must be transferable to larger industrial systems. As a benchmark for upscaling serve industrial systems with throughputs of up to 7 tons per hour (see meca-clay, SCHWENK-Zement/thyssenkrupp Polysius Grinding machines (CPV code: 43414000)
