Clinker size and cement grinding GCP Applied Technologies

Feb 10, 2021 An assessment of clinker “hardness” (for example by simply dropping 60-90mm balls from 1m height onto the larger clinker pieces) and the percentage 25mm are useful guides to 1st chamber ball charge selection and specifically the percentage at 90mm.


Feb 21, 2019 Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.

Analysis of the grinding behaviour of various Portland

The feed charge was prepared by pre-grinding the particulate material in the test ball mill. ... and the addition of higher percentages of clinker substitutes. ... carried out at 26 cement clinker ...

Dry Grinding Ball Load Calculation

Jul 03, 2017 The conclusion was reached that cement-grinding mills with 18 percent ball volume were doing poorly if they were of the overflow type. If they were of the low-pulp-level type, and the low-pulp-level devices keep the clinker charge low in accord with manufacturers’ claims, the efficiency was not impaired because of the small volume of balls.

Effect of chemical composition of clinker on grinding

Keywords: Clinker; Grinding; Fineness About 30% of the energy required to produce one ton of ity, whereas a high C2S content reduces grindability. The cement is consumed in grinding. It is a significant percent- more liquid phase there is, the lower is the grindability of age of the total cost of cement.

Physical Chemical and Electrical Analysis of Dust

dust generated from the first grinding process for the raw material and the second grinding process for the cement clinker in the cement plant. The results of elementary chemical analysis are expressed in weight percent of oxides. The raw material dust of the first grind-ing process primarily consisted of CaO (41.77), SiO2 (11.72%), Al2O3

Energy and exergy analyses for a cement ball mill of a new

May 01, 2020 It seems if the amount of ball charge increases, the clinker grinding improves through the mill because the total effective contact surface of balls increases; In addition, modifying the ball charge pattern of compartment 2 in order to increase the average surface of balls, can improve the cement CBM’s grind-ability.
