Cement - representative sample preparation is important
To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products has to be determined. At each stage of the production, samples have to be taken, processed and analysed to ensure quality control without gaps. Retsch offers a range of instruments that are used for sample preparation during the complete production process, from the quarrying of the raw materials to the final product. The typical sample preparation process involves preliminary size reduction, sample division and fine size reduction before the sample can be submitted to further analyses....
Comparative investigations on spinning rifflers
The influence of the degree of mixing of the material and the influence of the operating data of the apparatus were investigated in two spinning rifflers.
The Representative Sample Preparation of Waste
Now that a certain environmental awareness has developed in the population over the past few years, our efforts are geared not only to avoiding waste, but also to reducing the mountains of waste which still arise by means of raw material recovery and the reintroduction of secondary raw materials into the industrial cycle.
Vergleichende Betrachtung zweier Rotationsprobenteiler-Prinzipien
Zur Qualitätssicherung und Steuerung einer Produktion beschränkt man sich auf die Untersuchung von Teilmengen (Analysenmengen). Ziel der Probenteilung muß es daher sein, die in der Gesamtmenge eines zu untersuchenden Stoffes heterogen verteilten Eigenschaften repräsentativ in den einzelnen Teil- oder Analysenmengen wiederzufinden.
