最近几年,越来越需要开发一种能共效率更高的磨矿工艺。现已采用搅拌式球磨机(SAM—SalaAgitatedMill)进行了细磨试验.搅拌是用一个安装有伸出枢栓(由整体的碳化钨制成)的垂直转子进行的.磨矿介质尺寸(圆柱形体)、矿浆浓度、转子速度、介质水平和能量输入被认为是影响细店最主要的参数。本文讨论了这些参数对细磨磁铁矿石的影响.试验结果表明,在给定条件下(矿浆浓度、能量陷入和转子速度),采用3mm钢球,其能量效串要比8mm国柱形钢棒高约30%。把矿浆浓度、唐矿介质水平和转子速度具体地适当回合,可使塔矿效能达到最佳优.在每吨物料能量输入相同的条件下,以三种不同的矿浆浓度,把搅拌式球磨机与传统球磨机进行了比较。比较结果表明,在两种磨机均处于最佳效能时,搅拌式球磨机的细磨效能要高于传统球磨机30%~40%.
In recent years, there is an increasing need to develop a grinding process that can be more efficiently performed. Has been used in the mixing ball mill (SAM-SalaAgitatedMill) fine grinding test. Stirring is carried out with a vertical rotor fitted with a projecting peg (made of monolithic tungsten carbide). Grinding medium size (cylindrical body), pulp concentration, rotor speed, medium level and energy input are considered the most important parameters affecting the fine shop. This article discusses the effect these parameters have on finely ground magnetite. The experimental results show that for a given condition (slurry concentration, energy entrapment and rotor speed), a 3 mm steel ball is used, whose energy efficiency is about 30% higher than that of an 8 mm steel cylindrical bar. The pulp concentration, Tang mine media level and rotor speed specifically appropriate round, can make the best tower tower excellent performance. With the same energy input per tonne of material, agitator ball mills were compared with conventional ball mills at three different pulp concentrations. The comparison results show that the fine grinding efficiency of the agitated ball mill is 30% ~ 40% higher than that of the traditional ball mill when the two kinds of mills are in the best performance.
