Economics of Cement Grinding Aids

Economics of Cement Grinding Aids

The cost of cement grinding aid depends on the type of grinding aid and its content. Taking ordinary grinding aid with a dosage of 0.02% as an example, it will increase the cost of cement by 1.5 to 2.5 yuan per ton. However, in general, the power consumption per ton of cement grinding and the reduction of equipment maintenance costs will eventually offset the cost of grinding aids, or even exceed the cost increase brought by the use of grinding aids. The increase in cement production can increase sales and meet peak customer demand. In addition, there may be further benefits that can be obtained from changes in the cement composition (eg higher levels of limestone, slag, pozzolanic substances and fly ash when the quality is improved).

Therefore, the use of cement grinding aids can often bring high economic benefits. If the transportation cost is a large part of the cost of sales, the use of grinding aids can easily improve the "caking" phenomenon of the cement, which can reduce the transportation cost.

Therefore, the use of cement additives can reduce the transportation cost of cement, as well as the production cost of cement.

  in conclusion

1. The use of cement grinding aids can bring many benefits, including increased storage capacity by increasing bulk density, reducing "caking" phenomenon, and improving cement fluidity.
2. The "agglomeration" of cement corresponds to the compacted state, which is mainly caused by mechanical extrusion and mutual attraction between particles. The Cement Caking Index can be effectively assessed by laboratory test methods.
3. The fluidity corresponds to the non-compacted state. Cement grinding aids reduce the mutual attraction between particles and keep the cement particles in a dry dispersion state.
4. The cost of sales of cement depends on the time it takes for trucks, trains and ships to load and unload goods. The use of cement grinding aids can reduce loading and unloading during the entire transportation process, thereby reducing the total cost of sales. In some cases, transportation cost savings alone can compensate for the use of grinding aids.
