Broken Tooth in Raw Mill SeparatorOne of the plant's raw mill dynamic separators had a broken tooth, but no one knew about it (see images). SAM GUARD reported several issues related to the dynamic separator which were unclear to the team (see alerts list, left). Eventually, due to leakage ring maintenance, it was physically opened, and the broken tooth was identified.
Cement manufacturingCement 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 feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Industrial : Optimization for the Cement Industryand the adjustment of the feed and separator results in reduced variations in cement grade. This has the added benefit of a more consistent product quality. The control strategy is designed to respond to disturbances in the process but still achieve quality consistency. • Increased output. By continually monitoring both the loading of the mill and the balance of material flows through the ...
Raw Mix PreparationRaw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.
cement plantIn the cement production line, producing each 1 ton of Portland Cement need grinding at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials,gypsum).Grinding operation consumes power about 60% of total power in cement plants, raw material grinding takes more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%.
