bond grinding of clinker

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

Preparation of Cement Clinkers r oire

The clinker is ground with gypsum to a fine powder and becomes cement. This fine powder then reacts with water to bond together other components such as sand and aggregates. A properly prepared cross-section of a clinker can reveal a variety of information when examined under the microscope. • Shape and size of phases • Homogeneity of the mix

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.
