BT-2900 dry image particle size and shape analysis system mainly applies to the analysis fields of particle size and particle shape of coarse and granular material. It adopts advanced hardware technology including electromagnetic vibration feeding system, high light LED array light source, imported high speed CCD, little phrase difference telecentric lens, etc. During the process of free falling of particles, shoot particle images which pass the lens randomly. Meanwhile, software quickly recognizes and processes particles, and screen displays images, particle size and particle shape data for each particle in real time. As it adopts high-speed CCD that can reach 100 frame/min, thousands of particles can be shot and processed per minute, and image process software can recognize and extract adhesive particles automatically. These technologies improve analysis speed, precision and accuracy of particle image greatly.
