剖析了美国P－K公司V型真空干燥制粒机的主要机械设计和独特的性能，分析了在美国P－K公司试验室制取的混合料的性能，力图从理论和实践两个方面来验证该类设备在我国硬质合金行业上使用的可行性．从而为硬质含金行业制粉工序的更新改造提供可靠依据。以达到缩短制投工序工艺流程、改善生产环境、降低生产成本、提高产品质量的目的，促进我国硬质含金行业的发展。
The main mechanical design and unique performance of the P-K V-type vacuum drying granulator in the United States were analyzed. The properties of the mixture prepared in the laboratory of P-K Company in the United States were analyzed. The two aspects of theory and practice Verify the feasibility of using this type of equipment in China’s cemented carbide industry. Thus providing a reliable basis for the renovation and reconstruction of the flour milling process in the hard gold industry. In order to shorten the process of manufacturing process, improve the production environment, reduce production costs and improve product quality, and promote the development of China’s hard gold-bearing industries.
