The slurry grade analyzer uses X-ray fluorescence analysis technology for online detection of multiple slurries and various elements. This device overcomes traditional online detection methods by employing patented technology: Tablet-like inspection technology, which allows for the analysis of “dry materials” and eliminates the influence of slurry concentration and mineral particle size on detection accuracy. Throughout the detection process, there is no mutual interference between different slurry channels. Additionally, the system features a customized sampling and return design based on actual site conditions, making it more suitable for complex and harsh industrial environments.
