It extracts raw meal at different rates from several outlets in the silo bottom and mixes the stream from these outlets. The CF silo’s extraction system is governed by a programmable control unit.

Raw meal silo level measurement and point level

Before being burned in the rotary kiln, the material from the blending bed and the aggregates are ground to a fine raw meal in large mills. The powdery material is then transported to the silo by a pneumatic conveyor system. Reliable monitoring of the level is essential for optimal raw material storage.

Homogenization (BLENDING) Cement Plant Optimization

Homogenization (BLENDING) In preparing raw meal, raw materials like limestone, clay and iron ore are proportioned and fed to raw mill, where these raw materials are ground and well mixed. However, this mixing is not enough to produce clinker of uniform quality. For stable kiln operation and to obtain uniform quality of clinker it is necessary

2016-1-20  A mixed material, having a humidity rate of 2.82%, moves from the material silos into the raw mill. The kiln exit gases are conditioned in the gas conditioning tower to leave at 528.15 K, for pre-heating and drying the feed to the raw mill. In the mill, the mixed and dried materials exit as raw meal with a humidity rate of 0.48%, after grinding.

Re: Raw meal to clinker ratio Page 2 of 5

In a kiln which is being fed with raw meal at 350t/h and has a 'raw meal to clinker ratio' of 1.55 (calculated without respect to bypass), the actual amount of clinker produced with say 10t/h bypass dust removal will be;-(350 / 1.55) 10 = 215.8t. Therefore the 'raw meal to clinker factor' ,allowing for removal of this bypass dust, will be;-
