1.Crushing and pre-averaging

　　(1) Crushing.

　　In the production of cement, most of the raw materials, should be broken up, before used for cement. In these materials are limestone, clay, iron ore, coal, etc.. Lime stones of the most used for the production of cement.

　　When comparatively larger and larger solid particles, limestone crushing the desired size after extraction is important among all of the raw materials. A lot of crusher is used in the splitting of these raw materials, such as jaw crusher, impact crusher, cone crusher, vertical impact crusher shaft, etc. Accordingly, different material raw material, there are several relevant crusher, which can be used in the splitting process.

　　(2) Pre-homogenization of raw materials.

　　The technology of preliminary correction is the use of scientific regenerative technologies for the implementation of the initial homogenisation of raw material, so that the court of raw materials has simultaneously the function of storage and homogenization in the process of saving of raw materials.

　　2. Preparation of raw materials.

　　It will take at least 3 tonnes of materials (including raw materials, fuel, clinker and gypsum and gypsum stone) for production of 1 tonne of cement in the process of production. According to the data, the traditional type of dry cement from clinker consumes more than 60% of the energy of the whole plant. So the choice of crushing machines is very important.

　　3. The averaging of the raw materials.

　　In the process of obtaining cement the new technology of dry method, stability of clinker for the arrival of raw materials is a prerequisite for the entire system. System homogenization of raw materials plays a very important role in ensuring stability of the clinker for the arrival of raw materials.

　　4. The warming and decarbonisation.

　　(1) dispersion of materials.

　　The process of heat transfer on 80% is at the entrance of the pipeline. The raw material is fed into the heater, faced with the increasing flow speed is high, move the air and disperses.

　　(2) Gas-Separation of solids.

　　When the air enters the cyclone coupling with a powder, he must get up and move down until he comes to the end of the cone then up and is discharged through the vent pipe.

　　(3) Preliminary decomposition.

　　The emergence of pre-decomposition is a leap of technology of cement burning. This process is characterized by quality, efficiency and low-consumption, etc.

　　5. The burning of cement clinker.

　　Raw materials after heating and pre-decomposition in the cyclone heater, moves in a rotating kiln clinker. After that, the temperature starts to fall. At last high-temperature cement clinker is removed from the rotary kiln, and will be cooled up to the temperature which is suitable for the transport of transport, storage, and cementing. At the same time, the sensible heat of high-temperature clinker will be processed, in order to improve the thermal efficiency and quality of clinker.

　　6. Fragmentation.

　　Crushing is the last of the cement production process, but also the most time-consuming procedure. Cement clinkers are crushed to the correct size. The smaller the particle size, the better the final cement. There are a lot of crushing machines suitable for grinding of cement clinker, such as a mill, grinding mill, high pressure and Raymond mill, etc.. We will select a suitable machine for you according to your requirements. With reliable quality and certification, you can trust us.

　　7. Packing of cement

　　What you should pay attention after the production of cement, the packaging of cement. Essential to maintain the chemical and physical properties of cement over a long period of time.
