cement co2 emissions 2021
From 2015 to 2020, the global clinker-to-cement ratio is estimated to have increased at an average of 1.6% per year, reaching an estimated 0.72 in 2020; this rise was the main reason for the increase in direct CO2 intensity of cement production over the period. Dezeen has also pledged to become a net-zero business by 2025.

Grinding Ratio for Evaluating Grinding Wheel Performance
The length ac (δx) represents the volume of metal removed and the length be (δy) represents the volume of wear of tool and so the grinding ratio will be as follows: Volume of metal removed / Volume of wear of tool = δx / δy ADVERTISEMENTS: The grinding ratio normally varies from 75 to 125. The greater the grinding ratio the better wheel is.

CLINKER GRINDING UNIT PROCESS
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.
