Belite-based low-carbon clinker cements10 March 2020, Published under Cement NewsWhile Portland cement is expected to remain the most-used cement type in concrete production, alternative cements are gaining importance. This has seen the continued development of alternative clinkers, such as belite-based low-carbon clinkers with a belite content of more than 40 per cent, in China over the last two decades. By Tongbo Sui, Sinoma Research Institute, China, Hao Sui, Monash University, Australia, and Bin Wang, Sinoma Research Institute, China. Clinker used in the produ... |
Measuring opacity and particulate matter25 February 2020, Published under Cement NewsWith cement production being a potential source of several hazardous air pollutants (HAPs) that are subject to strict regulations to protect human health and the wider environment, AMETEK Land talks technologies available for the monitoring of smoke and dust emissions from the process. By Derek Stuart, AMETEK Land, UK. Figure 1: interactions between light and particles Among the most obvious of hazardous air pollutants (HAPs), as it is readily visible by eye, is particulate matt... |
Krasnoyarsk’s burner exchange24 February 2020, Published under Cement NewsThe burner system of Line 5 at the Krasnoyarsk cement plant in Siberia has been retrofitted from a direct-firing to a state-of-the-art indirect-firing system, courtesy of KHD Humboldt Wedag. The burner exchange project, primarily implemented to meet tighter emission regulations, yields further potential benefits for this wet-process plant.

The noise about fans11 February 2020, Published under Cement NewsFans are widely used to move air in a range of industries, including the cement industry. However, if not suitably insulated they can give rise to noise issues and impact the wellbeing of cement plant staff and local residents. In this article, Halifax Fan looks at noise levels from fans and how to reduce their impact. By Dr John Irons, Halifax Fan, UK, and Jessie Jia, Halifax Fan, China. Two sinter cooling fans located close to each other with ducting Sound is fluctuating air p... |
Connected manufacturing20 January 2020, Published under Cement NewsThe abundant and growing quantity of operational data and events collected in real time opens the door for improvements across the cement manufacturing process instead of only in specific areas. Operational data from existing devices and sensors that support automation and control systems can help increase asset availability, reduce energy costs and improve process efficiency. However, this is just the start of the potential offered to the industry by new technologies based on operational da... |
Sustainable lubrication14 January 2020, Published under Cement NewsOpen-gear drives of kilns and ball mills are often exposed to harsh operating conditions. While considerable advances have been made in terms of the design and manufacture of drives, tooth flank damage remains an issue due to excessive wear or material fatigue. Correct lubricant selection and application play a vital role in addressing the problem. By Werner Gschwandtner and Hermann Siebert, Klüber Lubrication Austria GmbH, Austria.

Boosting AF rates with flame thermography06 November 2019, Published under Cement NewsOver the past 30 years the cement industry has witnessed an increasing use of alternative fuels (AF), but the amount that can be fired in the main burner is limited by different process factors. To optimise AF firing in the main burner, VDZ has conducted several research projects with the aid of flame thermography. The know-how gained has been used to support producers seeking higher AF substitution rates, including a European plant that reached 100 per cent in the main burner without compro... |
