Description
Product Description
The various stages of the cement production process include crushing, pre-homogenization of raw materials, homogenization of raw materials, preheating and decomposition, firing, cement grinding and packaging.
Cement equipment mainly includes cement rotary kiln, cyclone preheater and grate cooler. As the main equipment for calcining cement clinker, cement rotary kiln is widely used in cement, metallurgy and chemical industry. It consists of cylinder, supporting device, supporting device with baffle wheel, transmission device, movable kiln head, kiln tail sealing device and combustion device, etc. It is characterized by simple structure, reliable operation and easy control of production process. Grate cooler is a kind of quenching type cooler, by blowing cold air to quench the clinker laying in layers on the grate plate to achieve the purpose of lowering the temperature.
The various stages of the cement production process include crushing, pre-homogenization of raw materials, homogenization of raw materials, preheating and decomposition, firing, cement grinding and packaging.
Cement production line is a line of equipment composed of a series of equipment to produce cement. It mainly includes the processes of crushing and pre-homogenization, homogenization of raw material preparation, preheat decomposition, firing of cement clinker and cement grinding and packaging.
Cement production line is a line of equipment composed of a series of equipment to produce cement. It mainly includes the processes of crushing and pre-homogenization, homogenization of raw material preparation, preheat decomposition, firing of cement clinker and cement grinding and packaging.
In the cement production line, at least 3 tons of materials (including all kinds of raw materials, fuel, clinker, mix, gypsum) are ground for every 1 ton of silicate cement produced. Statistics show that dry process cement production line grinding operations need to consume power accounts for about 60% of the power of the whole plant, of which raw material grinding accounted for more than 30%, coal grinding accounted for about 3%, cement grinding accounted for about 40%. Therefore, a reasonable choice of grinding equipment and process flow, optimize process parameters, correct operation and control of the operating system to ensure product quality, reduce energy consumption is of great significance.
Among the cement production methods, the silicate type cement process is representative. It is mainly based on limestone and clay as the main raw materials, after crushing, batching, grinding made of raw materials, and then into the cement kiln calcined mature materials, and finally add an appropriate amount of gypsum (sometimes also mixed with mixed materials or additives) and grinding and become.

Working Flow
Cement production equipment can be categorized into dry cement production line (including semi-dry method) and wet cement production line (including semi-wet method) according to the different methods of raw material preparation.
The advantage of dry production is low heat consumption (e.g., the heat consumption of clinker in dry kiln with preheater is 3,140-3,768 J/kg), but the disadvantage is that the composition of raw material is not easy to be uniform, the workshop dust is more, and the electricity consumption is higher.
Wet production has the advantages of simple operation, easy control of raw material composition, good product quality, convenient slurry transportation and less dust in the workshop, etc., but the heat consumption is higher (the heat consumption of clinker is usually 5234 ~ 6490 J / kg).

Dry Process | Wet Process |
1. Mixing of raw material in dry state in blenders. | 1. Mixing of Raw materials in wash mill with 35 to 50% water. |
2. The dry materials exiting the mill are called “kiln feed”. | 2. Materials exiting the mill are called “slurry” and have flowability characteristics. |
3. Fuel consumption is low i.e., 100 kg of coal per tonne of cement produced | 3. Fuel consumption is high i.e., 350 kg of coal per tonne of cement produced |
4. Cost of production is less. | 4. Cost of production is high |
5. Capital cost is high due to blenders. | 5. Capital cost (Cost of establishment) is comparatively less |
6. Size of the kiln needed for manufacturing of cement is smaller. | 6. Size of the kiln needed for manufacturing of cement is bigger. |
7. Difficult to control mixing of Raw materials, so it is difficult to obtain a better homogeneous material. | 7. Raw material can be mixed easily, so a better homogeneous material can be obtained |
