ESP morphs into bag filter

26 January 2021, Published under Cement News

When electrostatic precipitators are unable to meet tighter emission regulations, it can be more economical to modify them to bag filters rather than replace them with a new bag filter. Gorco SA highlights the key points to consider. By Eduardo Sauto, Gorco SA, Spain. Front view of the new bag filter with internal channel and bag plates Increasingly strict environmental emissions legislation has been a key driver behind the development of advances in gas filtration technology.

Tripling the lifetime of lining

11 January 2021, Published under Cement News

A Vietnamese cement plant has more than tripled the lifetime of the refractory lining in its cooler bull nose by using a precast modular lining from HASLE Refractories. Abrasion and alkali attacks have been reduced significantly, while the solution is also extremely resistant to coating. By HASLE Refractories A/S, Denmark. Figure 1: completed installation of HASLE precast Modular Lining in the cooler bull nose at a cement plant in Vietnam A 5000tpd cement plant in Vietnam, runni...

Keeping an eye on the gears

10 November 2020, Published under Cement News

One of the greatest mechanical challenges in rotary kiln maintenance today is maintaining the efficient operation of girth gear and pinion meshing. Misalignment during production creates uneven and unstable stress concentration on the teeth, resulting in component damage. An early-warning system can inform kiln operators long before the mechanical problem and any damages appear. By Paweł Kędzior, Havec Engineering Co, Poland. Misalignment of the girth gear affects every rotary kiln at...

From WHRPG to EfW

09 November 2020, Published under Cement News

As cement plants search for ways to reduce their carbon footprint, waste heat recovery power generation (WHRPG) systems are becoming more popular. The use of biomass also provides potential as an energy-from-waste (EfW) solution to produce electrical power. Developments in WHRPG and biomass/EfW power generation systems are discussed below, including new technologies for energy saving and environmental load reduction. By Kawasaki Heavy Industries Ltd, Japan. Figure 1: flow of a waste h...

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. ...

Holcim’s ‘ready to use’ belt

Steps to a smart factory

22 September 2020, Published under Cement News

Turkey-based Nuh Çimento has developed a solution for predicting cement strength. The project aims to estimate cement quality as precisely as possible at seven- and 28-day strength with the company’s new algorithm software and by adjusting the complete process accordingly with big data analysis. By Erbil Utku, Nuh Çimento, Turkey. Converting big data to added value: Nuh Çimento, Turkey, develops its ‘Dayanimci’ algorithm software and the ‘Kaptan’ platform for big data analysis ...

Elemental analysis to reduce cement’s carbon footprint

08 September 2020, Published under Cement News

Despite increasing market demand for cement in recent decades, the cement industry is required to reduce its carbon footprint. Elemental analysis can make a key contribution to this drive to lower CO 2 emissions from cement plants worldwide. By Ivo Nemetz, Elementar, Germany. The cement industry is facing the challenge of reducing its CO 2 emissions despite the need for increased cement production As the global cement industry moves forward as a 21st-century enterprise, it ...
