This R&D project will focus on microwave-assisted drying for nanosize particles. On the previous phase,**satisfactory results were obtained for microwave-assisted drying using multi-mode system at lab scale. For this**R&D project application of single-mode microwave system will be investigated and the performance of**single-mode and multi-mode systems will be compared.**Also detail technical analysis will be done on the operational parameters of microwave-assisted drying with**respect to technical requirements and specifications of an industrial microwave system. For this purpose, the**technical feedback of an industrial microwave manufacturer will be concerned. Besides, an investigation will**be carried out on microwave-assisted drying of raw material before ball milling. For ball milling operation a**minimum amount of moisture is needed, and microwave system can be used instead of conventional drying**systems.**Argex Titanium Incorporated, is developing a novel technology for producing titanium dioxide pigment**including preheating and dewatering. Therefore, low power microwave-assisted heating can be used for**preheating and dewatering. The main advantage of microwave treatment is selective heating due to material**type and size. In addition, reduction in energy consumption and process time would increase profit for pigment**production.

该研发项目将重点关注纳米颗粒的微波辅助干燥。在前一阶段，**使用多模式系统在实验室规模的微波辅助干燥中获得了令人满意的结果。对于这个**研发项目，将研究单模微波系统的应用，并对**单模和多模系统的性能进行比较。**还将对微波的工作参数进行详细的技术分析。符合工业微波系统的技术要求和规格的辅助干燥。为此，会关注工业微波炉制造商的**技术反馈。此外，还将对球磨前原料的微波辅助干燥进行研究。对于球磨操作，需要**少量的水分，可以使用微波系统代替传统的干燥**系统。**Argex Titanium Incorporated 正在开发一种生产二氧化钛颜料的新技术**，包括预热和脱水。因此，可采用低功率微波辅助加热进行**预热和脱水。微波处理的主要优点是根据材料**类型和尺寸进行选择性加热。此外，能源消耗和加工时间的减少将增加颜料**生产的利润。
