grinding of clinker tomake cement

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 producedby heating limestone and clay to the pointofliquefactionat about 1400°C-1500°C in the rotary kiln...Growing environmental concerns encourage the cement industry to improve its environmental performance, which in turn renews the interest in clinker grinding efficiency.

The following are several important factors affecting the cement clinker quality. In the process of clinker production, strict control of these factors can ensure the production of high-quality, high-yield clinker. 1. Lime Saturation Factor. The lime saturation factor (LSF) is a ratio of CaO to other oxides, it is used to control the proportion ...What Is Cement Clinker. Cement clinker is a semi-finished product obtained by mixing limestone, clay, and iron raw materials as raw materials in an appropriate proportion, burning to partial or full melting, and cooling. In the cement industry, the main chemical components of the commonly used Portland cement clinker are calcium oxide, silicon ...

The clinker grinding process is the stage where the particles are reduced in size, a combination of impact and abrasion and their efficiency depends on the controls realized on the size of the product, this stage of cement production is the stage with the highest energy consumption of the full process, in addition to being directly related to the properties and final...2grinding clinker replacement materials rev02 grinding clinker replacement materials rev02 grinding of clinker tomake cement2 grinding of clinker replacement materials introduction blended cements have been produced for decades in some countries and in recent years a renewed interest in the production of such cements can be found all over.
