Abstract: The spray granulator dryer has a mechanism of speed-gradient classifcation.A mathematical model of classification efficiency was proposed.The necessity of a drumscreen at the end of the cone was discussed.

摘要: 揭示了内返料内分级喷浆造粒干燥机的分级机理──速度梯度分级.建立了分级效率的数学模型,提出了分级效率的2个独立控制变量,指出了提高分级效率的途径和在锥小端增设筒筛的必要性.
