Cement Clinker Quality Control During Clinker

During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.

Chromium behavior during cement-production

2011-7-15  Behavior of chromium during cement-production processes. Formation of new chromium compounds in clinker with chromium oxidation states of +3, +4.6, +5, and +6. Addition of chromium altered the composition of the clinker phases, setting time, and compressive strength of hydrated mixes. Cr 3+ and Cr 6 were leached during leaching tests, whereas other species remained in the mortar.

Parametric Studies of Cement Production Processes

Cement production processes involve complex chemical and physical reactions during the conversion of raw materials to the final product. Moreover, the clinker burning process, which has a decisive influence on energy consumption and the cost of cement production, involves the combustion reaction of fossil fuel and a complex heat exchange between solids from raw materials and hot combustion gases [ 2,3 ].

Cement Clinker Quality Control During Clinker

In the clinker production of dry process, the calcined clinker is quenched in a grated cooler or a rotary cooler after being discharged from the kiln. Because there are two processes of liquid phase condensation and mineral intersection in the clinker cooling process, the cooling process will have a certain degree of impact on the clinker quality.
