振动研磨机普遍用于样品加工磨样工序。它具有封闭性能好,工作效率高,一次可同时磨细4～10个样品等特点。通过我们多年使用,发现磨样产品粒度合格率与磨样时间、人磨粒度及入磨矿量之间有着一定的关系,对此我们做了一些试验。 (一)磨样产品粒度合格率与磨样时间的关系我们选用硬度中等偏硬、较难磨(即含铁多)的物料作为试样。入磨粒度为1毫米,入磨量先采用100克,磨样时间分别以6分、8分、10分、12分、14分、16分、18分、20分、22分九个时间级进行试
Vibratory grinding machine is generally used for sample processing grinding process. It has a closed performance, high efficiency, can be ground at the same time 4 to 10 samples and so on. Through our years of use, we found that there is a certain relationship between the passing rate of grinding sample and the grinding time, the grinding particle size and the amount of grinding ore, and we have done some experiments. (A) grinding sample size pass rate and the relationship between grinding time We choose the hardness of medium hard, more difficult to mill (ie, iron and more) as a sample of the material. Into the grinding particle size of 1 mm, into the amount of grinding first with 100 grams, grinding time were 6 points, 8 points, 10 points, 12 points, 14 points, 16 points, 18 points, 20 points, 22 points nine time Test
