Breakthrough in Clinker Grinding

grinding seeks to reduce materials from roughly one meter cubes of blasted stone to a size where at least 80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The

CLINKER GRINDING IN CEMENT PRODUCTION

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.

Clinker Grinding. Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter - grinding in mills.

Cement clinker - Wikipedia

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Cement mill - Wikipedia

The hardness of clinker is important for the energy cost of the grinding process. It depends both on the clinker's mineral composition and its thermal history. The easiest-ground clinker mineral is alite , so high-alite clinkers reduce grinding costs, although they are more expensive to make in the kiln.
