BT-2800 Dynamic Image Granularity and Shape Analysis System Introduction
The BT-2800 dynamic image particle size analysis system is a dynamic particle size analysis system using sheath flow technology. It consists of a microscope, a sheath flow sample cell, a micro pump, an imported camera, and a stirring dispersion system. Its working process is to put the sample into a beaker to make a suspension with a certain concentration. After the sample is dispersed through a stirrer and a disperser, the sample is extracted with a micro pump and injected into the sheath flow sample cell. At the same time, the sheath The liquid pump also injects sheath fluid (usually pure water) into the sheath flow sample cell and wraps the sample flow in the middle. The two flow through the sample cell together. During the flow, the camera continuously captures particle images through the microscope and transmits them to the computer. The analysis was performed in order to obtain the particle size and shape parameters.
Unlike the static image particle size analyzer, which captures stationary particles on a slide, the BT-2800 takes particle images in the state of particle flow. This is the origin of the dynamic image particle size analysis system. The advantages of this system are as follows: First, automatic sampling is achieved through a micro-pump and agitation and dispersion system, which not only simplifies operation, but also reduces the influence of human factors and improves accuracy. The second is to be able to shoot continuously and differently. Each sample can shoot tens of thousands, hundreds of thousands, or even hundreds of thousands of particles. The analysis of so many particles ensures that the samples are representative and the results are accurate. The third is to use edge recognition technology for image processing, which can process 1 to 20,000 particles per minute. At such an image processing speed, the image and granular shape data of each particle can be displayed on the screen in real time while shooting, and the analysis can be obtained. As a result, the shooting ended and the results came out at the same time.
The analysis items of BT-2800 include two categories: particle size and particle shape. The particle size analysis items include the particle size of each particle, the largest particle, the typical value, the content in a specific interval, the content less than or greater than a certain particle size, the particle size distribution data and distribution. Curve, etc. Granularity analysis includes the roundness, aspect ratio, convexity, ellipticity ratio, and solid volume of each particle. At the same time, the distribution data and curve of each particle shape parameter can be obtained.
BT-2800 has the characteristics of clear imaging, fast analysis speed, simple operation and accurate and reliable results. The main application fields are technical research, applied research and quality control in the fields of artificial diamond, silicon carbide abrasives, wollastonite, fibers, spherical aluminum powder, spherical graphite powder and other areas to provide a high-precision analysis method. Features
With sheath flow technology, particles are lined up through the focal plane of the telecentric lens to ensure that each particle is imaged clearly and overcomes the phenomenon of image blur due to defocus.
The use of a telecentric lens and a high-speed CCD avoids image distortion and smearing, making the analysis results accurate and reliable.
Using multi-threading and edge recognition technology, it can process 10,000 particles per minute. The shooting speed is synchronized with the image processing speed, which ensures the representativeness of image analysis. Technical Parameters
