提高粉状物料造球效果的技术措施是基于对微造球机理的认识。假定了基于第一中心和第二中心的两种微造球机理。为了描述和解释原料粒度结构组成对微造球机理的影响,定义了两个新参数,即N1和N2两个比率,并介绍了关于N1、N2重要性的的试验结果和相关技术措施。 Technical measures to improve the pelleting effect of powdery materials are based on the understanding of the mechanism of micro-pelletizing. Two kinds of micro-pelleting mechanisms based on the first center and the second center are assumed. In order to describe and explain the influence of particle size structure on the microsphere-making mechanism, two new parameters, N1 and N2, were defined. The test results and related technical measures about the importance of N1 and N2 were introduced.
