during grinding process, which is deeply influenced by the presence of the active components (alkanolamines and glycols) of cement additive, or better of Grinding Aids (GA). INTRODUCTION The introduction of GA, started more than 50 years ago, has as ultimate task the prevention of cement particle re-agglomeration during and after milling ...
A grinding aid prevents this agglomeration to improves the grinding efficiency. The aid is generally added to the clinker at a fixed rate from 0.01% to 0.03% before entering to a finishing mill. As a result the grinding improves by 4% to 6% per 0.01% addition of aid. The aid also improved the dispersibility and fluidability of cement (powder ...
Grinding aids enhance the grinding and separating efficiency which leads to an increased production rate. Additionally, the resulting lower content of over ground particles meets the characteristics of a more favorable particle size distribution with better cement quality.
The use of grinding aids in cement had an unforeseen and unusual effect on testing in cement plants. During the 1930s the typical test for fineness was 325-mesh sieve fineness. Since the fineness of cement with grinding aids was so different, the use of the Wagner test was instituted by the grinding aid producers to demonstrate the effect on ...
Grinding aids are common cement additives, and can consist of several different types of compounds such as alkanolamines, glycols or phenolic compounds. These are used to increase the throughput of cement clinker in the grinding mill. Generally, the concentration range of grinding aids added is from 50 to 500 ppm. After the grinding
