Kiln Feeding Cement Plant Optimization

Kiln feed metering: Almost all modern cement plants have adopted an indirect weighing system like solid flow meter, rota-scale etc. with a dosing gate as a pre-feeder to feed kiln within a tolerance range of ± 2 %. However standalone volumetric system (like screw feeder) and gravimetric system (like weigh feeder) feedings are still existing in

Homogenization (BLENDING) Cement Plant Optimization

For cement plants of small capacities where preblending by staking-reclaiming was not a necessity, batch type blending (Air merge-turbulent blending) to achieve a blending ratio of 10-1 was enough to produce a consistent kiln feed. However, as the plant capacities grew bigger and bigger, Batch type silos to contain a buffer stock of 2-3 days

Cement manufacturing components of a cement plant

Cement 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.
