Brazil gives OK to VRM

Published 20 June 2016

Brazilian cement producers, like many others in the sector, have continually sought to improve their operations and advance their output by achieving higher grinding capacities, improved efficiencies, increased clinker substitution and finer product residues. Vertical roller mill technology has played a key part in this development. By Jared Weston, FLSmidth Inc, USA.

The Brazilian cement industry is a frontrunner in terms of producing cement with a low carbon footprint and high energy efficiency. With a long tradition in the production of blended cements, Brazil has a clinker-to-cement ratio below 70 per cent, making it one of the lowest in the world. Production of blended cement with materials such as slag, fly ash, limestone and pozzolan minimises CO2 emissions and energy usage by reducing the fuel combustion and emissions from processing raw materials during clinker production.
