Solid, high-quality pellets are an important precondition for reliable and meaningful XRF analysis. With the PP 40, RETSCH offers a pellet press which presses a wide range of materials such as slag, ores, minerals and cement to strong pellets with a smooth surface. The PP 40 features an individual pressure force regulation in the range of 50 to 400 kN. Besides controlling the pressure force, it also determines build-up, maintenance and release of force during pressing. This reduces the inner tensions of the sample and ensures that even difficult materials are pressed perfectly.
