随着粉体的应用范围扩大,对粉体的要求也越来越高,为满足粉体工业的需要,持别是对热敏﹑热塑物料微粉碎的需要,笔者主持和参与了一种适合热敏﹑热塑物料的微粉碎机组的研制工作。该机组利用冲击粉碎原理,粉碎机内无筛板筛网,采用机外分级,在无任何辅助冷却的条件下,实现了低温升的目的。经生产试验取得了非常满意的效果。本文重点介绍了研制的目的,机组的主要结构﹑特点,设计参数和性能指标,以及机组的应用范围。从试验和生产实践的结果来看,该机组对热敏﹑热塑物料的粉碎效果,具有其他设备无可替代的优点。 With the expansion of the application of the powder, the requirements for the powder are also getting higher and higher. In order to meet the needs of the powder industry, the need for fine grinding of the thermosensitive and thermoplastic materials is met. The author presided over and participated in a For thermal ﹑ thermoplastic materials mill crusher research and development work. The unit uses the principle of impact crushing, grinder no screen sieve, the use of machine classification, without any auxiliary cooling conditions, to achieve the purpose of low temperature rise. After the production test has been very satisfied with the results. This article focuses on the purpose of development, the main structure of the unit features, design parameters and performance indicators, as well as the application of the unit. From the test and production practice results, the unit of thermal ﹑ thermoplastic material crushing effect, with other equipment irreplaceable advantages.
