PRODUCTION OF GRANULAR ALKALI METAL TRIPOLYPHOSPHATE OF HIGH ABRASION RESISTANCE AND HIGH APPARENT DENSITY |
摘要 |
<p>Production of granular alkali metal tripolyphosphate of high abrasion resistance and high apparent density. An alkali metal tripolyphosphate of which between 10 and 40 percent of its particles have a size smaller than 0.03 mm, the balance particles having a size of between 0.03 and 0.4 mm, is granulated by spraying an alkali metal orthophosphate solution thereonto; the resulting granules are dried; undersize and oversize particle fractions are separated from the dried granules; and the remaining fraction of particles is annealed at temperatures of between 300 and 600 DEG C.</p> |
