Rotor mill CSM series

impacthorizontalfor powders

The CSM 50 & CSM 80 laboratory classifier mills combine a mechanical impact mill with an integrated, dynamic air classifier. Very fine grains free of coarse particles can be achieved with the help of this infinitely adjustable classifier wheel. The self-regulating internal circulation of the coarse material inside the machine housing creates an extremely stable operation. In the past, multiple-step processing such as the conventional grinding-classifying-process with fine impact mills and subsequent coarse grain separation in an air classifier, was the process of choice. The integration of a mechanical impact mill and a dynamic air classifier in a single housing offers the user numerous benefits. The user friendly design of the machine housing enables fast, complete cleaning of the machine when product or batches are changed. The plant is designed to be modular, so that other modules can be added, such as our CGS Fluidized Bed Jet Mill and High-efficiency Classifier Model CFS/HD-S to make a completely versatile laboratory platform. • Finenesses from d97 10 µm to d97 150 µm (based on limestone) • Rotor impact mill with rotating classifier wheel to limit the maximum particle size • Exactly defined maximum particle size through integrated dynamic air classifier • Classifier wheel with simultaneously rotating immersion tube to achieve highest finenesses, infinite adjustment • Gap between classifier wheel and fines outlet rinsed by gas for highest possible prevention of oversize particles in the product • Classifier shaft seal rinsed by compressed gas to protect the bearings • Separate drives for grinding disc and classifier wheel
