The cement industry’s energy challenge

03 November 2021, Published under Cement News

With global cement demand expected to rise by as much as a quarter by 2050, the industry faces a range of challenges to produce in a more sustainable way. One aspect is to reduce its energy input to reflect tighter emissions legislation. By Fabio Mielli and Juliano de Goes Arantes, Rockwell Automation, USA. Green construction and decarbonisation is expected to impact the way cement plants manage their energy consumption Worldwide trends such as increasing population numbers and ...

Energy saving with separate fine grinding

13 October 2020, Published under Cement News

Separate grinding and subsequent blending is a commonly used practice in the cement industry, enabling the lowering of the specific electric energy demand by using highly efficient comminution techniques. While ball mills are not the most energy-efficient mills, VDZ’s research has shown that in some cases ultrafine grinding by means of a stirred media mill combines the advantages of a ball mill with low overall specific energy demand. By J Knappert, S Seemann and PM Fleiger, VDZ, Germany. ...

Argos awarded Energy Star certification

20 September 2018, Published under Cement News

Cementos Argos announced it was awarded Energy Star certification by the US Environment Protection Agency for the third-consecutive year. The certification was awarded as a result of the company’s performance in terms of energy use at its Harleyville (SC), Newberry (FL) and Roberta (AL). The facilities fall within the 25 per cent top works with the best energy performance.

Coal classification

07 November 2016, Published under Cement News

Dr Clark understands that the accepted ways of classifying different types of coal have led to complications when plant personnel have been required to estimate the specific thermal energy consumption of cement kilns. The accepted ways of coal classification are not always useful in estimating the volume of this fuel required to fire the kiln Cement manufacturing is a capital-intensive industry where control of costs is paramount. To recover the capital investment required to...

Cementos Argos

29 March 2016, Published under Cement News

Cementos Argos has announced measures to help reduce its energy consumption as part of the Colombian government’s energy-saving drive. By supplying excess energy from its plants to the national grid and limiting the use of its mills during peak hours, the cement producer hopes to save the equivalent of the consumption of around 100,000 homes each day and almost 130,000 homes during peak hours. This could contribute close to 10 per cent of the energy-saving goals set by the government. The...

Best energy consumption

16 February 2015, Published under Cement News

When it comes to achieving the best energy consumption, what are the key factors a cement producer needs to address? In this article, extracted from the newly published Cement Plant Environmental Handbook (Second Edition), Lawrie Evans presents a masterclass in understanding and optimising cement plant energy consumption. By Lawrie Evans, EmCem Ltd, UK. Figure 1: electrical energy (MWh) index across 14 countries, 2013 As control of sources, generation, distribution and consumpti...

Sustaining European cement

02 June 2014, Published under Cement News

The current economic recession is providing the European cement industry with a challenging business environment. Resource and energy efficiency, carbon sequestration and reuse, low-carbon cement and downstream initiatives all provide opportunities for creating a cement sector that is more sustainable, both in terms of the environment as well as costs. In an interview with the European cement association, CEMBUREAU, ICR talked with CEO Koen Coppenholle and his team about the challenges ahead...

Behind the numbers

30 July 2012, Published under Cement News

The Cement Sustainability Initiative’s “Getting the numbers right” project has seen the creation of a sizeable and influential database on cement plant emissions and energy consumption, which has just been updated with 2010 data. Phil Kerton of CPK Consultancy, UK, takes a first look at some of the interesting values and trends that can be extracted from this important resource. It is the sixth year that the Cement Sustainability Initiative publishes data on cement industry CO2 emissi...
