CTS-9907066G.I. Tardos and P.R. Mort, CUNYA theoretical framework for better understanding and prediction of physical chemistry, fluid flow and powder mechanics processes in binder granulation will be developed. The basic process consists in agglomeration of fine powders into larger granules using liquid binder. Granule growth, consolidation, deformation and breakup will be simulated and compared to experimental results. Experiments will be performed in a laboratory constant shear Couette granulator. Large-scale laboratory (at CCNY) and pilot scale granulators (at Procter and Gamble Co.) will be used to verify the scale-up capabilities of the simulations. This is a GOALI university-industry collaborative research project between CCNY and Procter and Gamble Co. The industrial principal investigator will co-direct the research and co-mentor the doctoral student. Periodical visits and other interactions are planned between the university and industrial personnel. If successful, the project will provide a new method and a predictive tool to design and scale up granulators in a variety of processes in chemical, pharmaceutical and food industries.

CTS-9907066G.I.塔尔多斯和公关部为更好地理解和预测粘结剂造粒中的物理化学、流体流动和粉末力学过程，将建立一个理论框架。 基本过程包括使用液体粘合剂将细粉末附聚成较大颗粒。颗粒的生长，固结，变形和破碎将被模拟，并与实验结果进行比较。 实验将在实验室恒定剪切Couette试验机中进行。 大规模实验室（CCNY）和中试规模制粒机（Procter and Gamble Co.）将用于验证模拟的放大能力。 这是CCNY和宝洁公司之间的GOALI大学-行业合作研究项目。行业首席研究员将共同指导研究并共同指导博士生。定期访问和其他互动之间的大学和工业人员的计划。 如果成功，该项目将提供一种新的方法和预测工具，用于设计和扩大化工，制药和食品行业各种工艺中的造粒机。
