On the plus side
Phase one of Russian construction company Atomstrojkomplex’s new cement facility in Yekaterinburg is a grinding unit, for which Intercem Engineering will provide its high-efficiency ICS plus 145 separator. Developed in house, the high-performance separator has been designed for increased efficiency and higher cement fineness. By Intercem Engineering, Germany. Separator circuit with the...
Belite-based low-carbon clinker cements
While 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 belit...
Measuring opacity and particulate matter
With 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 avai...
Krasnoyarsk’s burner exchange
The 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 proje...
The noise about fans
Fans 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...
Connected manufacturing
The 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...
Sustainable lubrication
Open-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 iss...
Boosting AF rates with flame thermography
Over 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...
China steps into the lime light
As the urbanisation rate in China increases and the government legislates for a more sustainable society, the use of lime is set to expand. This is expected to lead to the modernisation and consolidation of the count...
Novel no-cement refractories
For the areas in cement plants impacted by high wear or corrosion, refractory specialists have developed new no-cement refractory materials based on electrochemical bonding. A 25 per cent silicon carbide material has...
Efficient grinding meets reduced CO2 emissions
While cement plants have made sound progress in terms of reducing CO 2 emissions from fuel consumption, progress relating to such emissions from electricity consumption has been slower. VDZ looks at a key power cons...
External circulation technology for VRM raw meal grinding
The pressure differential of a traditional vertical roller mill (VRM) system for raw meal grinding is high, with the fan accounting for about 45 per cent of power consumption. Sinoma International Engineering has dev...
Countdown for Bardon
As part of LafargeHolcim’s Capital Markets Day in 2018, guests enjoyed a site visit to Europe’s largest aggregates quarry at Bardon Hill, east of Coalville, Leicestershire, UK. Owned by LafargeHolcim subsidiary Aggre...
The digital quarry
Quarries often give the impression that they have been forgotten in capital investment projects, having bypassed technological changes for several years. However, the quarry is where production starts and here, moder...
Processing depth for AFs
In his paper ‘A new approach to burning alternative fuels’, delivered at the Cemtech Europe 2018 conference in Istanbul, Turkey, Oral Turesay of KHD Humboldt Wedag introduced the concept of ‘processing depth’. His th...
Portland cement, lime and alkali-activated binders
Following on from last month’s discussion regarding the production of alternatives to Portland cement clinker, Arthur Harrisson takes a closer look at alkali-activated binders. Fly ash needs to be activated to...
