常见的测定采矿场出场原矿水分的方法有以下几种;(一)采用随机抽样法取出整车原矿样,用地中衡称重,然后在由一整套破碎、筛分、取样、计量和选别设备组成的工艺流程中,进行加工和缩分,得到干矿重量和各种小样。这种方法需要有一个完备的原矿取样、加工系统,其规模相当于一个小型甚至中型选矿厂,只有少数大型矿山才能办到。(二)采用随机抽样法取出整车原矿样,用地中衡或台秤称出湿净重,然后全部烘干,再称出干净重,二者相减即为水分。此法一般矿山都能办 There are several common methods to determine the raw water content of the mining field. (1) The original sample of the whole vehicle is taken out by random sampling method, the balance of the soil is weighed, and then the total amount of water is measured by a set of crushing, screening, sampling, Equipment composed of the process, the processing and shrinkage, dry weight and a variety of sample. This method requires a complete raw ore sampling and processing system, the size of a small or medium-sized beneficiation plant, only a few large mines can do. (B) the use of random sampling method to remove the original vehicle prototype, the scale of the site weighs or scales weighing wet weight, and then all dried, then weighed clean weight, the two subtraction is the water. This method can generally do mine
