摘　　要：目前瓜尔胶生产线中的筛分设备在现实生产的使用中,大量粒度合格物料无法及时透筛,之后反复粉碎,造成大量粒度小于0.038 mm的胶粉,影响整体产品质量。为解决该问题,对普通旋振筛的结构和工作原理进行了深入分析,并在其基础上研发出新型的高效旋振筛。对新型高效旋振筛的工作能力进行了试验测试。结果表明,新型高效旋振筛的筛上物中细粒级含量比普通旋振筛低近30%左右,筛分效率也比普通旋振筛高。When the screening equipment of the guar gum production line is in operation, there are a larg number of material particles which are small enough but can＇ t get through the screen cloth in time. These materials will then be shattered repeatedly to make a lot of materials with particle sizes smaller than 0. 038 ram, therefore the quality of the products is influenced. To solve this problem, a study of the structure and operating principle of the circular vibratory screener is done. A new and high-efficient circular vibratory screener is designed, base on the structure of ordinary circular vibratory screener. The capability of the new circular vibratory screener is tested by experiments. The experiment results show that the percentage of smaller particle size material on the screen surface of the new circular vibratory screener is almost 30% lower, and the screening efficiency of the new one is higher than the ordinary one.
