本文所叙述的粒度测量方法是一种分离方式的方法,它适用于连续工作的测量装置。该装置中,使用横向气流配置,相等于颗粒下落速度的气流驱动试样连续进入测量装置(每小时几公斤)。在测量区域中,颗粒大小顺序排列,在一定的点上,总是可能出现同样大小的颗粒,用移动式的吸收测量装置,测量该区域内具有颗粒的数量。电子计数器把测量信号转换成密度曲线和分布曲线对于测量颗粒分布所需的时间大约10秒。虽然是几次探测周期的累计,但不确切地说,可以获得较大范围。本装置可测量如5到150微米或10到300微米小颗粒范围。
The particle size measurement method described herein is a method of separation that is suitable for continuous operation of measuring devices. In this device, a stream of particles equal to the falling velocity of the particles is used to drive the sample continuously into the measuring device (a few kilograms per hour) using a cross-flow configuration. In the measurement area, the particle sizes are arranged in order. At certain points, it is always possible to see particles of the same size. With a mobile absorption measuring device, the number of particles in the area is measured. The electronic counter converts the measurement signal into a density curve and a distribution curve for about 10 seconds to measure the particle distribution. Although several times the cumulative detection cycle, but not exactly, you can get a larger range. The device can measure small particles such as 5 to 150 microns or 10 to 300 microns.
