摘要: 研究了搅拌磨和球磨磨矿产品的粒度特性及其磨矿过程中的比生产率、能耗情况.结果表明:搅拌磨磨矿产品较为均匀,球磨磨矿产品中微细粒和粗颗粒的质量分数较高;分别采用直线和指数曲线拟合搅拌磨和球磨时不同入磨粒度和比生产率的关系,随着入磨粒度的下降,球磨的比生产率下降较搅拌磨明显;采用Walker等提出的关系式,拟合入磨粒度与能量消耗的关系,搅拌磨的耗能增长速率远小于球磨的增长速率.搅拌磨相对于球磨在细磨和超细磨过程中具有明显的优势.

关键词: 搅拌磨, 球磨, 粒度, 比生产率, 能耗

Abstract: The particle size characteristics, specific productivity rate and energy consumption were studied in the grinding process of stirred mill and ball mill. The results showed that the product of stirred mill was more uniform than that of ball mill, and the mass fractions of fine grain and coarse particle of ball mill are higher than that of stirred mill. The straight line and exponential curve were respectively used to fit the relationships between different grinding particle size and specific productivity under stirred mill and ball mill, and the specific production rate of ball mill decreases obviously with the decrease of mill feed size. The equation formula proposed by Walker et al was used to fit the relationship between mill feed size and energy consumption, and the energy consumption growth rate of the stirred mill is much smaller than that of ball mill. Stirred mill has obvious advantages over ball mill in the process of fine grinding and ultra-fine grinding.

Key words: stirred mill, ball mill, grain size, specific production rate, energy consumption
