Abstract. White Portland cement can be used such as decorative coatings, masonry regularization as the skin coat, and many other applications mainly due to the Cement production is associated with a considerable environmental load (Nie 2013 ), which first needs to be fully understood before effective measures can be The LCA of portland cement production in China SpringerLink
Abstract. Portland cement is one of the heavy chemical process industries. This chapter is dedicated to address the refractory requirements for a cement The Holcim Portland Precalciner Cement Plant near Florence, Colorado is one of the largest in the United States. It has an annual production capacity of 1.9 million tons of cement and its preheater tower, a 328-ft-tall, Preheater Tower Structural Strengthening

Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates. More than 30 raw materials are known to be used in the manufacture of portland cement, and these materials can be divided into four distinct categories: calcareous, siliceous, argillaceousThe thermal efficiency becomes critical for the heat exchange-controlled steps preceding clinker sintering.

1 Introduction. In 2008, the global cement production stood at 2.8 billion tons, up to 3.4 % from the previous year according to World Bank. After 4 years, China witnessed its cement production up to 2.18 billion tons accounting for more than 60 % of global production according to China Cement Association (CCA 2013 ).the portland cement kiln system. Sulfur in cement kilns is derived from both kiln feed and kiln fuel. The form of the sulfur dictates the location in the kiln where the SO2 generation takes place. Sulfur in the fuel is oxidized in the burning zone or calciner, and is easily removed by reactive lime present in the kiln.Formation and Techniques for Control of Sulfur Dioxide

The typical silicate module of a white cement clinker is 4 to 6 (in contrast to 2.3 3 of grey Portland cement), and its aluminate module is 15-20 (that of grey Portland cement being 1.5 2.5).

Cement production plants with clinker capacities between 700 t/d and 2,000 t/d generally are the best choice for medium-scale cement manufacturers. They are easier to design and build than large cement plants, and have higher economic efficiency than mini cement plants.
