The worthy waste - Indian Cement Review

In case of fly ash based cements it is preferred to have co-grinding of fly ash and clinker. However in case of slag a different practice has proved to be economical and efficient. Slag and clinker are ground separately and then blended together to get the final product. Cause of variation The next challenge is the quality of fly ash.

Very few papers have been published on the inclusion of coal ash in clinker, the main components of which are silica and alumina. According to Kaminskas and Kubiliuté (2010), the composition of coal ash is as follows (in wt %): SiO 2 (35-60%), Al 2 O 3 (15-35%), Fe 2 O 3 (5-20%), CaO (0-10 wt%), and traces of MgO, SO 3 and alkalis.

Introduction to Petroleum Coke - American Energy Alliance

While petcoke is similar to coal, petcoke generates just 0.2 percent of America's electricity, while coal generates nearly 40 percent. Instead, petcoke is usually used as a fuel to make cement, lime, , glass, steel, and fertilizer as well as many other industrial applications. Much of the rest of the petcoke is "calcined petroleum coke."

grinding coal efficiency

Experimental studies with Kentucky bituminous coals have shown that ash content has a significant influence on the coal's grindability. For the Kentucky coals studied, the specific energy consumption in grinding the coal to 10 urn, at which 90 percent liberation of the mineral matter can be achieved, exceeds 400 kwh/ton for high ash-content (> 20%) coals, while less than 100 kwh/ton .
