Verder Scientific: Solutions for the cement industry

Published by
World Cement,

To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products needs to be determined. At each stage of production, samples are taken, processed and analyzed to ensure quality control without gaps. CARBOLITE GERO, ELTRA, RETSCH and RETSCH Technology offer high-quality solutions for heat treatment, elemental analysis, sample preparation and particle sizing of a vast range of products in the cement industry.

CARBOLITE GERO: Heat treatment

CARBOLITE GERO offers a range of furnaces for quality assurance of raw materials and process testing. The AAF 1100 °C Ashing Furnaces and CWF 1200 °C or 1300 °C General Purpose Furnaces are ideally suited for 'loss on ignition tests'. For combustibility testing the RHF Furnace (1600 °C) is the perfect choice.  

ELTRA: Elemental analysis

With its offering of combustion analysers using resistance or induction furnaces or both, ELTRA covers a wide range of applications for C and S determination in organic and inorganic samples. Thermogravimetric analysers for LOI testing are also part of the product portfolio.

RETSCH: Size reduction and particle size analysis

RETSCH provides size reduction and sieving equipment designed for sample preparation and characterisation of solids: Jaw crushers for crushing and disc or ball mills for pulverising samples; pellet presses for producing smooth tablets for XRF analysis; air jet sieve for standard-compliant grain size analysis.

RETSCH TECHNOLOGY: Particle characterisation

RETSCH Technology is the leading manufacturer of image analysers for measuring particle size and particle shape of bulk materials. The CAMSIZER systems use Dynamic Image Analysis to produce precise and reproducible results in real time.
