Comparison between grinding of cement clinker with and without grinding aid (after Fuerstenau, 1990) Figure 1 shows the typical comparison between grinding of cement clinker with and without a grinding aid in a laboratory mill. As discussed in the literature [1,2,4], there was significant effect of using grinding aid in cement grinding.

The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.

Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary ...

The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in real-scale grinding plants. In fact, laboratory-grinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement …

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 ...

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...

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.
