Std. Dev. Of Silo feed / Std. Dev. Of Kiln feed • Automatic continuous samplers are installed at the silo feed point and silo extraction point • Samples are taken and analyzedregularly for monitoring the homogenizing efficiency of the silo and the final homogeneity of the kiln feed which is the most important parameter, to control

After grinding, the powdered raw mix, is stored in a raw meal-silo where blending takes place. Blending is done by injecting compressed air. Generally blending ratio is 1:10. This powder material (Raw meal) is fed to the kiln for burning.

We at FRIGATE has full range of equipment required for efficient & trouble free Silo feeding, Storage & extraction for flat bottom as well as inverted cone silos. Open and Closed Air Slides.

Your productivity relies on a process that handles product flow capably, reliably and efficiently. The Controlled Flow silo provides optimal flow, homogenising efficiency and significant power reduction at low investment cost. It operates continuously and is built to blend, homogenise and store cement raw meal.

The design of modern blending silos isdescribed by Halbleib (2003). Blending silos should be monitored by: blending ratio (s(..,jsr-M,) compressor power {kWh/t of throughput). Blending silos are prone to internal build-up of dead material, particularly if raw meal is wet or aeration defective.

The CF (Controlled Flow) silo is a contin-uously operating system for homogeni-zation and storage of cement raw meal, where the material is extracted simul-taneously at different flow …

equipment Raw meal metering equipment plays an im-portant role in the cement production. Prior to feeding the preheater of the kiln, raw meal ex-tracted from a blending or storage silo is continuous-ly weighed by means of flow meters. Often, a weighing prebin installed on load cells is used. This prebin allows the control of the weighing system

meal preparation [4,5]. Raw meal homogenization occurs during the stage of raw meal preparation and involves a series of steps, including crushing, mixing, and grinding. By continuously mixing during storage and transport, the chemical composition of the raw meal is made uniform, ensuring consistent reactions during calcination and improving ...

Layers of raw meal of varying chemical composition are fed to the silo. The variations in extraction rate/residence time mean that these layers are broken up as they proceed down through the silo. The resulting raw meal product, extracted from the silo during any stage of the extraction sequence, will there-fore be a mixture of raw meal compo-
