control to the dust formed at grinding of clinker

The cooled clinker is a kind of granular material with different particle size. They will be ground in the grinding mill to reach the qualified fineness of cement product. During the grinding, 2-3% gypsum powder is added as retarder so that when cement contacts with water, its …

Environmental Guidelines for Cement Manufacturing

than 0.2 kilograms (kg) of dust per metric ton (kg/t) of clinker using dust recovery systems. NOx emissions should be controlled by the use of proper kiln design, low NOx burners and use of an optimum level of excess air. The NOx emissions from a dry kiln with preheater and precalciner is typically 1.5 kg/t of clinker

Some measures to improve the grindability of clinker in a

Feb 05, 2021 As can be seen from Table 2, the clinker grinding time remained high in 2015 compared with the same period in 2014, on the premise that the clinker powder was ground to 350 10m /kg. After adjusting the raw material fineness control target, the grinding time in 2016 has been on a downward trend and gradually recovered to about 32min.

What is the manufacturing process of Portland Cement

It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2-3% percent of GYPSUM. Several types of Portland cement are available. The most common, called ordinary Portland cement (OPC), …

Production process and main equipment of cement plant

The production process of cement is simply two grinding and one sintering, that is, raw materials are mined, crushed, ground and mixed to produce raw materials. Raw materials are fired at 1450 ~ C high temperature to produce clinker. Clinker is crushed and ground together with gypsum or other mixed materials to become cement. Due to the difference between dry and wet raw meal preparation, the ...
