to conventional grinding plants. But on the other hand, standalone grinding plants are strongly dependent on locally sourced raw materials, as well as clinker, which is subject to extensive transport and multiple trans-shipments. This may result in variable quality, seasonal moisture content, and more dusty and fine clinker.

We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thouh of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.

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.
