Figure 3.1 Typical Mimic sample of the Raw Mill Section 4. ENERGY SCENARIO 4.1 Electrical Energy System The cement plant receives electricity supply from the Captive Power Plant (CPP) (12 MW) and DG sets. It is distributed to various sections of the plant. An energy meter is installed on 110 kV feeder incomer, which records
In the diagram above of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At A, the raw meal largely decarbonates at B, the temperature is 1000 C - 1200 C and intermediate compounds are forming and at C, the burning zone, clinker nodules and the final clinker minerals form.
Mar 01, 2018 A Norwegian cement plant producing about 1.3 million tons of cement per year was used as a case study. A mass and energy balance was made for the raw meal department, and process data available from the plant process database as well as manually measured gas flow rates were used to calculate the available heat.
The ATOX coal mill is suited for various installation types, whether inert or non-inert, and direct or indirect firing systems. An inert system designed for indirect firing is the most common solution for cement plants. Equipped with the high-efficiency RAKM dynamic separator, the ATOX coal mill will grind any type of coal to the required
Regardless of the specific purpose of a feed plant, material flow follows a basic pattern (see Figure 1). 2. RECEIVING. The first operation in the feed processing plant involves the receiving of raw materials into the plant premises. Feed ingredients arrive in sacks, or other small containers, and in bulk.

the wet process, the raw materials are ground, mixed, and fed into the kiln in their dry state in the dry process (Avami and Sattari, 2007). Table 2.3 presents the energy requirement for operational equipments in a typical process, while Figure 2.3 illustrates a
The raw mix is fed into a circular storage unit called a raw mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a raw mill bin called the raw mix bin for grinding. The other raw materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore.
As the per-flow diagram of the wet process of cement manufacturing, the rotary kiln is an essential and important component of a cement manufacturing factory. 6.
