Grinding aids for high performance cements

2018-3-29  Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development. In this paper we present a typical example of full investigation about the possibility of producing high early strength type I cement, using an appropriate cement

Best energy consumption International Cement Review

2015-2-16  Cement grinding For cement grinding, the technology development away from ball mills has taken a different route. The development of roller presses in the 1980s took advantage of the benefits of higher-pressure grinding and many presses were retrofitted to ball mills as pregrinders.

SINTEF REPORT

2015-8-29  grinding is responsible for around 40% of the total energy usage during cement production [21]. Therefore intergrinding is a potential way of saving considerable amount of energy since some mineral admixtures have a clear positive influence on the grindability of clinker.

2006-2-1  1.. IntroductionSchönert (1979) has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. Compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls (HPGR) (Schönert and Knobloch, 1984).The first commercial application of HPGR was in 1985 and its success
