浅析TEC大颗粒尿素造粒机内颗粒的成长时间

Simple analysis of particle growth time in TEC granular urea granulator

通过对流化床造粒机中尿素颗粒成长时间的分析,分别就床层高度、产品粒度、破碎机破碎晶种粒度、造粒负荷等操作变量对停留时间的影响,提出在尿素颗粒的成长时间不变的情况下,为保证产品粒度分布及产品水含量的高品质产品的生产,为实际生产调节床层高度、床层温度及返料比等操作提供了操作依据。

By means of analyzing growth time of urea granules in fluidized bed pelletizer, the effect of operating variable on residence time, such as bed height, product size, seed size in crusher, granulation load. In case growth time of urea granules changeless, ensuring high quality production in size distribution and water content of products, providing a basis for actual producing in bed height, bed temperature and recycle ratio.
