Simplified process of cement production:

 

Raw materials extraction (mining) → crushing→ raw materials storage and pre-homogenization (ball mill) →raw material homogenization and storage, calcinations (raw material enter into rotary kiln after pre-heater in cyclone tube, calcinated to clinker) → cement grinding (mix other chemical material according to cement quality to grind) → cement storage and transportation

 

1. Crushing

In this process, most of raw material should be crushed, such as limestone, clay, iron ore and coal. Limestone is the largest amount of raw materials in cement production line, so it is very important in cement production line.

 

2. Pro-homogenization

Raw material pro-homogenization is making the raw material yard with storage and pro-homogenization function by applying scientific stacker technology.

 

 

3. Raw material preparation

In cement production process, to produce 1 ton of Portland cement must grind at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials, gypsum). According to statistics, grinding operations in the dry-process cement production line need to consume power accounts for about 60% of the whole plant power, of which 30% of raw material grinding, more than about 3% of coal mill, cement grinding about 40%. Therefore, a reasonable choice grinding equipment and processes, optimizing the process parameters, proper operation and controlling operation system is of great significance.

 

 

4. Raw material pro-homogenization

The system of raw material pro-homogenization plays a raw meal of raw ingredients stability of pit entry last gatekeepers.

 

 

5. Preheat & decomposition

Raw material preheating and decomposition is completed by preheater, which can improve the kiln system productivity and reduce heat consumption of clinker Purposes.

 

6. The burning of cement clinker

Raw material is carried out into the rotary kiln clinker for completion after preheating in the preheater and pre-decomposition

 

7. Cement grinding

Cement grinding is the last process of cement production line, also the most power consuming process. Its main function is to grind the cement clinker (and gelling agent, performance tuning materials, etc.) into the appropriate size and a certain particle size distribution, which is for increasing the size of its hydration, accelerating the hydration rate and meeting the coagulation, hardening requirements.
