转速对高速斜盘分级机分级效率的影响

重点介绍高速斜盘分级机在中国黄金集团中原矿业有限公司进行的分级试验,并对高速斜盘分级机的分级原理进行阐述,试验过程中通过调节转速,考察了高速斜盘分级机各产品的产率及粒度变化,分析了转速对高速斜盘分级机内部离心力场以及分级效果的影响,测定不同转速下底流产品及溢流产品的品位变化。试验结果表明,转速对高速斜盘分级机分级效率有显著影响,提高转速,分级效率升高,但转速过高,分级效率会降低;高速斜盘分级机的分级粒径低至10μm以下,细粒级矿物10μm分级具有可行性;高速斜盘分级机在分级过程中兼具有脱泥的特点,可以实现连续作业,解决了当前泥质矿物影响浮选指标的技术难题。

Effect of Speed on Efficiency of High-speed Inclined Plate Classifier

This paper focuses on grading test of high-speed inclined plate classifier in zhongyuan mining co, LTD of china gold group, and expound the classification principle. By adjusting speed in the process of test, examined the change of productivity and grain size of high-speed inclined plate classifier products, analyzed the effect of speed on the centrifugal force field of high-speed inclined plate classifier and efficiency, measured the grade change of overflow and underflow in different speed. Experimental results show that the speed have a significant impact on grading efficiency of high-speed inclined plate classifier, increased speed will improve the grading efficiency in a certain extent , but too high will reduce the grading efficiency; the grading size of high-speed inclined plate classifier low below 0.010mm, 0.010mm classification become a feasible of fine minerals; high-speed inclined plate classifier has the characteristic of desliming in the process of classification, can achieve continuous operation, solved the technical problems of the current shale influenced the flotation index.
