基于旋转圆盘干燥机，以建筑用砂为实验材料，搭建单个垂直旋转圆盘传热实验台，在能量守恒的理论基础上，分析研究垂直旋转圆盘的转速、物料颗粒粒径、物料填充率对传热性能的影响。研究表明圆盘转速对传热性能影响较大，几乎呈线性增长关系；物料颗粒粒径和物料填充率分别对平均传热系数呈近似线性下降关系和近似线性上升关系；圆盘表面气膜传热热阻约为颗粒传热热阻的26倍。实验对优化圆盘干燥机参数等有一定的参考价值。

Based on the rotary disc dryer, with the building sand as the experimental material, to set up a single vertical rotating disc heat transfer test bench, based on the theory of energy conservation, analysis of the speed and the particle on the vertical rotating disc diameter, filling rate effect on heat transfer performance. The research shows that the disk rotation speed on the performance of heat transfer effect is large, almost linearly; granular material particle size and material filled rates were on the average heat transfer coefficient is decreased in a near linear relationship and approximate linear increasing relation. disc surface film thermal resistance is about 26 times the particle heat transfer resistance. The experiment has a certain reference value for optimizing the parameters of the disc dryer.
