Effect of Grinding Aids in Compressive strength and setting time Grinding Aid will increase Compressive strength of the cement differently according to the time a laboratory test is performed and generally around 5% increase but the actual mechanism of grinding aids in the cement is not clear and may be due to fine grinding of the clinker
Effect of grinding aids on closed circuit cement grinding As introduced before grinding aids are sprayed in the mill or added on the clinker with dosages usually ranging from 100 200 g up to 2 3 kg per ton of cement Once a grinding aid is added during cement manufacturing the main effect is the reduction of separator reject more

OPERATION AND CONDITION OF THE GRINDING CIRCUIT IN ORDER TO IDENTIFY AREAS OF IMPROVEMENT PREVENT PROBLEMS AND TAKE STRATEGIC DECISIONS The Mapei TAG Technical Assistance Group team is made up of professionals able to perform Mills Audit in order to help customers to optimize the milling operations with the
same dosage of grinding aid the Mapei Dosing Lance promotes its dispersion and consequently its efficacy in enhancing performance Conclusion The Mapei Dosing Lance is designed to help to optimise the dosage of grinding aids in VRMs to produce cement Its design prevents any loss of grinding aid caused by the stripping phenomenon inside the
For example in cement grinding mills these additives increase production by 10% to 15% and reduce the amount of energy required for the grinding process by 8% to 12% The additives also improve cement properties such as mechanical strength and flow rate and reduce wear on components in the grinding units The optimum dosage of Mapei
4 The optimum gypsum can be very different if a grinding aid is used duri ng cement production This allows interesting results to be obtained in terms of higher compressive strengths and better pe rformances References [1] Climate Change Cement and the EU Cembureau publication Available at the URL
MAPEI laboratories that withstand the temperatures and mechanical stresses typical of the cement grinding process in ball mills or vertical mills It should be noted however that the acrylic polymers used in most concrete admixtures would deteriorate during the cement grinding process losing much of their effectiveness
