对选矿物料和产品的筛分,-200目的细级别都离不开水析。这对于准确估计有用矿物的分布、改善工艺条件、提高回收率都有着重要意义。 水析常用斯托克斯公式。固体颗粒的沉降速度正比于固体密度和颗粒直径的平方,而且和颗粒的形状有极大关系。但对-400目的微细级别,假设形状为球形的物体,在极 Screening of mineral processing materials and products, -200 fine level of purpose are inseparable from the water analysis. This is of great significance for the accurate estimation of the distribution of useful minerals, improvement of process conditions and improvement of recovery rate. Stokes equations commonly used in water analysis. The settling rate of solid particles is proportional to the solid density and the square of the diameter of the particles, and has a great relationship with the shape of the particles. However, the fine level of -400 purpose, assuming the shape of a spherical object, in the very
