On Figure 2, homogenizing silo technology from company IBAU can be seen. In this technology, only a batch of material is homogenized at a time and drawn from the silo. ... For example, for a raw meal silo in a cement plant, the aeration may start and stop according to kiln feed bin level while raw meal silos are feeding the rotary kiln. On ...
Consistency in raw material is vital for the production of cement with reliable characteristics. As the process of cement production has developed, so has the preparation and storage of the blend of materials used to produce clinker. This paper will discuss some of the history of how raw material has been produced, stored, and transported to the kiln. …
Homogenizing Silo. Let us say there are five different raw materials, A, B, C, D and E. According to the blending strategy, let us assume A, B and C are proportioned and …
There are two basic homogenizing processes for dry raw meal i.e. Batch process and continuous process. In the batch process, at least two pairs of double deck silos, each consisting of a blending silo at the top and a storage silo below are used. Sequence of operation of the silo i.e. filling, blending and storing is made independently.

composition of the feed to the kiln raw meal. The first parameter is regulated during grinding of the raw meal. Variation of the second parameter is related to deviations of the raw meal quality at the mill outlet and mixing ratio of the homogenizing silo. 2.1 Raw meal production A simplified flow sheet of a closed raw meal grind-
process as well as for raw meal storage. The feeding of the silo takes place via a novel type of parallel distributor (1) ensuring a controlled build-up of the different material layers. Homogenizing of the raw meal is achieved by causing the layers of dif-ferent CaCO 3 content (2) to flow together by funneling (3) flows and thus merging with ...
Re: raw meal silos. Hey; Generally; silo or aerated gravity silo systems are designed according to these three concepts: 1- As inverted cone silos. 2- As central chamber silos. 3- As multiple-outlet silos. 1- The inverted cone concept: The inverted cone silo represents the pure concept of the aerated gravity silo.

Well-proven homogenizing and storage system 2 How it works 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 rates from a number of outlets in the silo bottom. The CF system, including suitable kiln

and the raw meal composition. In Figure 1 a typical flow chart of raw meal production is shown. Figure 1. Flow chart of raw meal production . In the closed circuit process demonstrated, the raw materials' feeding is performed via three weight feeders, firstly feeding a crusher. The crusher outlet goes to the recycle elevator and from there it
The raw meal collected by the two cyclones is transported to the raw meal homogenization silo (CF silo, or controlled flow silo) by and air slide and elevator. 5. Raw Meal Homogenizing and kiln feeding System Kiln feeding system is mainly comprised of CF-silo and LOW (loss of weight) unit .CF-silo is for raw meal storage and homogenizing.
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. Your productivity relies on a process that handles product flow capably, reliably and efficiently.

Raw Meal Homogenizing Silo. IBAU Raw Material Homogenization Silo . 1 Brief introduction The IBAU silo uses continuous even technology of Germany IBAU company, and is equipped with a mixing silo outside IBAU silo. A big cone is designed in the middle bottom of IBAU silo, so raw material inside silo can be transferred to silo wall from the …
2. Good homogenizing effect Working Principles: The working principle is the raw materials in the top of silo are scattered evenly by eight chutes, and during different periods, the raw material are scattered sideways. The inflatable system on the bottom of silo is designed accords with fluidity of the raw material aerated.
sampling of raw meal ex raw mill. chemical analysis of total sample: main elements LSF. split sample into sub-samples: < 32 mm fraction 32 – 90 mm fraction > 90 mm fraction. chemical analysis of sub-samples: main elements LSF. calculate separation factor (SF): LSF<32mm/LSFtot. Þ range of not critical raw meals: 0.8 < SF < 1.2.
Homogenizing of raw meal is always done in The silo system may be : Continuous Multi-Stage Silo Areation Unit The air and energy requirements for the homogenization of the raw mix depend on : Variations in the composition of the raw mix entering the blending silo Desired quality set point of the fully blended product
