Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.

A certain cement plant had undergone a problem in the roller in which the treads were subjected to frequent wear. The plant was inspected, their log book was verified, and the complete procedure of welding was checked. Crack was formed on the roller mill's base material because of being subjected to high subsurface thermal stress.
Grinding Aids are used in the cement mill (Ball Mill, Vertical Roller Mill, HoroMill) to increase the productivity, save electrical energy and/or to increase the fineness and improve defined cement properties, e.g. powder flowability. A typical example is SikaGrind®-400.
The cement rotary kiln. When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln. We are AGICO, a professional cement equipment manufacturer and cement plant contractor.
