Ultrafine selection at your fingertips

Cement producers can enhance the performance of their products by adding ultra fine filler to the ground clinker. Ultrafine particles have a d50 of < 3 μm. Other minerals industries can also benefit from using ultrafine filler. For instance, ultrafine grinding and classifying of limestone can allow producers to replace more expensive and polluting fillers.

The FCB TSV™ classifier is known for its high performance separation capabilities and minimal electricity consumption. The more than 250 operational installations and the satisfaction of its users demonstrates the performance and reliability of this system in the field, which is mainly focused on (but not limited to) the processing minerals and cements. The primary benefit of this system is the high level of production efficiency that it offers to grinding plants. It enables the reliable and accurate control of the distribution of the products’ particle size, and optimises the inherent qualities of finished products themselves (sharpness of PSD curves, burnability of cement raw mix, controlled combustion of solid fuels, cement strength, etc.).

The FCB TSV technology has been extended and is now also available in the UHF (Ultra High Fineness) field with a Tromp curve cut-size lower than 3 µm. It allows UHF powder production with d50 down to 2 µm. The FCB TSV UHF is designed to address the production of such fine powders at an industrial scale, up to 15 tph throughput in a single wheel classifier.

Natural mineral materials such as limestone as well as industrial products like granulated blast furnace slag, have already been experimented on and evaluated for suitability.
