【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.
[Abstract]:The particle size characteristics, specific productivity and energy consumption of agitated and ball milling grinding products were studied. The results show that the mineral products of agitation mill are more uniform, and the mass fraction of fine particles and coarse particles in grinding products of ball mill is higher, and the relationship between particle size and specific productivity of agitation mill and ball mill is fitted by linear and exponential curves, respectively. The specific productivity of the ball mill decreases more obviously than that of the agitated mill with the decrease of the particle size of the ball mill, and the energy consumption growth rate of the mixing mill is much lower than that of the ball mill by using the relation formula proposed by Walker et al to fit the relationship between the particle size of the ball mill and the energy consumption. Agitating mill has obvious advantages over ball mill in fine grinding and ultrafine grinding.
