Abstract (en)
[origin: EP1489161A1] The purpose of the procedure is to produce Mn minitablets with a concentration of between 90 and 98% of this metal, the binding material being Al particles. The procedure is based on using electrolytic Mn ground from flakes of a chemical purity of 99.7% or more, while this product is screened by means of a sieve with a mesh of 450 microns or less, where the fine powder content must be below 15%. Similarly, atomised Al powder produced by mechanical means must be used, with a grain size of 100 to 800 microns and with over 80% of the powder between 350 and 720 microns. The procedure is executed in a device with a storage hopper (1), a product diffuser (4) in that hopper (1), a hopper for compacting (6) and forming the minitablets in dies (9), in combination with pressing punches (7) and (8) and with the assistance of a honeycomb dispensing valve (10) interposed between the feeder chamber (5) and the compacting chamber (6). <IMAGE>
