These grinding mills installed on three Cementos Moctezuma sites have accumulated over 1 500 000 hours of operation to the end of 2022. Furthermore, the mills cope with the latest cement quality requirements and new types of cement recipes to reduce carbon footprint of the plant.
The grinding model wins out over the clinker producing one in this scenario. In the wider picture in August 2019 Cemento Cruz Azul ordered two petcoke grinding mills from Germany's Loesche and Austria's Unitherm Cemcon said it had been awarded the supply of an MAS DT burner to an unnamed cement plant.
For ball mills, it is more efficient to reduce the size of large particles prior to the mill, using physical means such as a hammer crusher, pre-grinder, or a roll press. Fine clinker is less of an issue in a ball mill, since the material simply passes through to the second chamber for fine grinding, although this can reduce the impact of the ...
