Cement clinker

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres ( in) to 25 millimetres ( in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilie materials such as clay during the cement kiln stage.

Addressing the Unwanted Impacts of Grinding Aids

Cement additives are mainly dosed onto the clinker belt close to the inlet of the mill. Frequently, the clinker is hot and parts of the cement additive evaporate (as can be seen in Figure 1). Therefore, good ventilation must collect the evaporating gases and/or respiratory protective equipment should be used.
