Clinker. Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is released (also known as process emissions). A substantial amount of heat is needed to start and sustain the chemical ...

Fuel is combusted to produce heat for the clinker production process; coal is the traditional fuel used in China's cement industry. The raw coal from the stockyard is crushed in a hammer crusher and fed to the coal mill. The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator.

How Does Clinker Cooler Reduce Cement Production Energy Consumption

How Does Clinker Cooler Reduce Cement Production Energy Consumption

The main power consumption of a clinker cooler is its cooling fans. It usually takes m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to m 3, the air consumption efficiency will be 15% lower than that of other cement ...

What is a Clinker? | Coal Bins Chimneys | Forum

This clinker is about 18" long and 8" wide. It was created by burning highash, low AFT bituminous coal. AFT is ash fusion temperature, or the temperature that the ash will become liquid and flow and stick together. It doesn't show real well in the photo, but there are lots of areas that look like melted glass.
