Grinding aid or grinding additives refer to substances which when mixed into the mill contents cause an increase in rate of size reduction [1]. These terms are very common in cement industries where it is used to increase the throughput to the mill. Grinding aid also affect the cement
TAVERO#174; grinding aids make life easier for busy cement producers. Our grinding aids are designed to increase mill output without increasing costs, while saving energy and reducing CO 2 emissions. Improved cement flowability reduces the effort for handling and transporting cement.

MasterCem cement additives amplify grinding efficiency, resulting in a higher mill throughput and lower the clinker factor, with an overall reduction in CO2 emissions. Our performance enhancers modify and elevate cements properties, improving its strength,
Cement grinding aid composition (22) (43) (57) A grinding aid composition for improving the efficiency of cement grinding. The grinding aid composition comprises: an alkanolamine compound that is a primary alkanolamine compound, a secondary alkanolamine compound, or a mixture thereof; and a glycol.
A cement mix according to the invention comprises: the grinding aid composition as described above, cement clinker, gypsum, and optionally one or more fillers such as flyash, bagasseash, fumed silica, limestone, construction debris, etc.
#0183;#32;Grinding aid is a chemical agent used to make it easier to grind and mix cement. The grinding aid began to gain popularity in the mid20th century as a reliable tool for cement processing. Its effectiveness and reputation for reliability lie in its ability to reduce surface tension between cement particles brought on by the stress of the grinding process.
