  • PRESS-GRANULATING PROCESS OF NON-DUCTILE SALTS
    Publication number: 20170129823
    Abstract: Process of press-granulating non-ductile salts and salt mixtures, such as kieserite (MgSO4.H2O), langbeinite (K2SO4.2MgSO4), polyhalide (K2SO4.MgSO42CaSO4.2H2O), arcanite (K2SO4) and anhydrite (CaSO4) for preparing stable, storable granulate, by pressing a mixture of fine grains of salt and a viscous, sugar-containing additive, such as molasses having a total sugar content in the dry matter of from 47 to 55%, by roller pressing at pressures up to 260 bar. The press scraps initially obtained, which are ductile, are solidified by maturing of the material at temperatures between 20 and 40° C. and maturing times of 3 to 8 hours prior to crushing them in impact mills and sieving.
    Type: Application

  • Press-granulating process of non-ductile salts
    Patent number: 9592514
    Abstract: Process of press-granulating non-ductile salts and salt mixtures, such as kieserite (MgSO4·H2O), langbeinite (K2SO4·2MgSO4), polyhalide (K2SO4·MgSO4·2CaSO4·2H2O), arcanite (K2SO4) and anhydrite (CaSO4) for preparing stable, storable granulate, by pressing a mixture of fine grains of salt and a viscous, sugar-containing additive, such as molasses having a total sugar content in the dry matter of from 47 to 55%, by roller pressing at pressures up to 260 bar. The press scraps initially obtained, which are ductile, are solidified by maturing of the material at temperatures between 20 and 40° C. and maturing times of 3 to 8 hours prior to crushing them in impact mills and sieving.
