在闭路流程中使用圆锥破碎机和立式冲击(VSI)破碎机来比较这两种不同破碎设备的破碎效果。闭路流程中的破碎机破碎的最终筛孔尺寸为9mm。生产量、粒度减小和能耗对比结果表明,VSI破碎机能量利用率比圆锥破碎机要高很多,并且产品粒度也更细。与圆锥破碎机相比,VSI破碎产品中小于1mm物料含量为65%,并且能耗更低。根据所选择的能量度量法来评估破碎机为磨矿提供更细物料的好处。该方法表明,VSI破碎机可以为磨矿节省2%～14%的能量,这取决于所使用的能量模型和最终产品的粒度。该评估与在磨矿之前采用VSI破碎机破碎铁矿时节省11.8%的能量相符。
Cone crusher and vertical impact (VSI) crusher were used in the closed circuit to compare the crushing effect of these two different crushing plants. The final screen size broken by the crusher in the closed loop is 9 mm. Production volume, particle size reduction and energy consumption comparison results show that, VSI crusher energy utilization rate is much higher than the cone crusher, and the product size is also finer. Compared to cone crushers, VSI crushed products have a content of less than 1 mm of 65% and lower energy consumption. Evaluate the benefits of the crusher to provide finer material for grinding based on the energy measure chosen. The method shows that VSI crushers save 2% to 14% of energy on grinding, depending on the energy model used and the particle size of the final product. This assessment is in line with the savings of 11.8% when crushing iron ore with a VSI crusher prior to grinding.
