Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locallyavailable raw materials which make up the bulk of the raw meal.

The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C, where it is transformed into a molten mixture inside the rotating kiln. At the temperature of 1450 °C the minerals in the raw meal undergo chemical reaction to form a new compound known as Clinker, which is the precurser for the production of cement.

• cement is ground much finer than raw meal • the feed to a cement mill is often completely dry and is significantly more difficult to grind than raw materials • requirements to the particle size distribution of the finished product are much more strict when grinding cement than when grinding raw materials

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.

They are used in grinding of cement raw materials (raw meal) ( limestone, clay, iron ore), cement clinker and cement additive materials ( limestone, slag, pozzolan) and coal. Multicompartment ball mills are relatively inefficient at size reduction and have high specific energy consumption (kWh/t).

The main constituents of the raw meal, which is a carefully proportioned mixture of cement raw materials, are lime and silica. Lime is included through calcium carbonatecontaining rocks such as limestone or marl. For silica, on the other hand, the principal source is clay. These are followed by alumina and iron oxide.

May 29, 2018· Monitoring and controlling the grinding grade is an essential factor in maintaining cement quality and production efficiency. This must be done during the grinding process from raw material to raw meal, and also during fine grinding of burnt clinker with additional core components or .

Construction work at the Oaxaca Lagunas plant started in August 2018. Mechanical erection of the raw materials feeding workshop and the FCB Horomill grinding circuit started in July 2019.

The raw materials are analyzed in realtime using crossbelt analyzers and in the plant laboratory, blended in the proper proportion, and then ground even finer. Plants grind the raw materials with heavy, wheeltype rollers that crush the materials into powder against a rotating table. After grinding, the material is known as raw meal and is ...

vertical roller mill for cement grinding is also called raw meal vertical roller mill, and it is the core equipment applied for cement raw meal grinding. It is a new type of high efficiency, energy conservation and environmental protection of grinding equipment, ...

Perfect grinding produces a fine powder termed as raw meal which is preheated and sent to the Kiln. The material is heated to between 1250 – 1300 degrees celcius before being dramatically cooled by burst of air in the cooler. This produces the principal ingredient known as Clinker which is the basic material for cement production.

two separate Cement Production lines can be summarized into the following processes ;as can be seen in the process and Quality flow diagram below; 1. Quarrying and Crushing 2.
