Simoloyer CM100s: semi-continuous mechanical alloying on a production scale using cycle operation-part II

摘要

The production of large quantities of powders forindustrial appellations, e.g., in paints or soldering materials,especially Cu and Ag particles with a special geometry (flakes) areof high interest, based on milling experiments resolved by the HighEnergy (ball) Mill, the Simoloyer CM1-1-?1, with a grinding unitcapacity of 0.5 1 for laboratory purpose, a new grinding device, theSimoloyer CM 100s 1 (capacity 100 liters), has been developedunder the same principle. The new device is suitable for a semi-continuous production of mechanically alloyed and mechanicallydeformed powders (1-3), which is described in part I of this work.Part II focuses on testing and industrial application of theprocessing equipment as well as on principles regardingproductivity. The testing regarding semicontinuous operationusing depression has been performed and is discussed in thepresent paper. The production capability has been determined at 10kg per 3 minutes. The challenge of the semi-continuous procedureis to get access to this batch-result without additional serving-times. From the present point of view, the route usingcompression has the highest potential which will be considered inpart III of this work. The main processing parameters will lead to acontinuous capability of about 4 tons of flake-powder per day (10hours), which relates to a time-saving factor of approximately1000 compared to conventional ball-milling and stampingtechnique. The determination of the energy consumption (energybalance) by use of the special control-software will also be discussed.
