Data on Clinker and Cement Production. The task of entering the data on clinker and cement production is related to a mass balance which should be determined on at plant level. The following plant mass balance diagram will help you to obtain the requested values as required for correct calculations.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
The clinker manufacturing process. The clinker manufacturing process starts with the extraction of the raw meal from the homogenization silo to insure that the raw meal is stable and homogenized in order to produce consistent clinker quality.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln fee...
