Nov 30, 2016 Stacking raw materials/fuels and reclaiming them is an essential part of cement industry. Stacking of raw material is done in order to have sufficient raw material to feed the plant during any unforeseen supply stoppage. Also, stacking and reclaiming is done in specific pattern to blend the material and ensure uniformity in material for stable ...
The raw meal is in the form of a dry powder, is heated and burnt in a pre-heater, kiln and then cooled in an air cooling system to form a semi-finished product, known as a clinker. Clinker (95%) is cooled by air and subsequently ground with gypsum (5%) to form Ordinary Portland ement (OP).

The lime saturation factor (LSF) is a ratio of CaO to other oxides, it is used to control the proportion of cement raw meal. In the operation of the cement kiln, the thermal system of the kiln can be affected by the fluctuation of LSF. The high saturation ratio will make the raw meal difficult to burn to clinker.
