Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Manufacturing Process of Ordinary Portland Cement (OPC)

The raw mixture prepared is heated in large rotary kiln up to about 1400-1450 °C. A series of chemical reaction occurs as the temperature rises. The peak temperature is maintained so that the material does not contain sinter products. Sintering is the process of melting the mass of the material.

OPERATIONS STRATEGIES FOR VERTICAL SHAFT LIME KILNS

The calcimatic kiln or rotary hearth kiln is a circular kiln with a slowly revolving doughnut- shaped hearth. In fluidized bed kilns finely divided limestone is brought into contact with hot combustion air in a turbulent zone usually above a perforated grate. An emerging process is the parallel flow regenerative(PR) lime kiln ( Parson 1988).

kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter. Wet process and long dry process pyroprocessing systems consist solely of the simple rotary kiln.
