精确及可比较的分析很大程度大取决于样品的精确处理。只有对样品来源具有代表性的样品才能确保测试结果的效度。旋转管式分样仪确保了选取的样品的代表性及分析的可重复性。 PT200旋转管式分样仪是处理无尘样品和大体积样品减量的前提。它适用于粉末和颗粒材料的处理。 通过调节分样缝的宽度，可控制分样比例及所分得的样品量。

作用原理
需进行分样的样品由进样漏斗进入，通过进样仪的插槽而进入到旋转管式分样仪内。通过上部圆锥内以恒定转速（50转/分钟）转动的转动管，所有进样料流能够均一地分布于底锥的分样圆周上。可更换的底锥带有1个、2个或者3个分样缝，对其可进行不受级数限制的缝宽设置。旋转管每转动一圈就有相应分样比例的样品进入到样品接收容器中。剩余样品被收集到底部的弃置样品接收容器中。

New Solutions for Cement and Concrete
The cement and concrete industry is one of the key pillars of the global construction sector. Without cement, there would be no stable buildings, roads, or bridges: it is the binding agent of modern infrastructure. Every year, billions of tons of cement are produced worldwide to meet the growing demand for housing, transportation networks, and industrial facilities. The industry is characterized by stringent quality requirements, complex chemical processes, and continuous development toward more sustainable and energy‑efficient material technologies.
No Representative Analysis Results without Correct Sample Division
Faultless and reproducible analysis results are closely linked to an accurate sample handling. Only a sample representative of the initial material can provide meaningful results. Rotating dividers and rotating tube dividers are an important means to ensure the representativeness of a sample and thus the reproducibility of the analysis.
