Overview of Cement Production Line:

The birth of cement production lines has become another emerging equipment in the mining machinery industry. With its rigorous structure and efficient performance, it has become the main choice for many manufacturers in mining applications. As a major production enterprise of cement production line, Songshan Heavy Industry has developed its own theory after years of research and summary, ensuring the rational utilization of materials and the qualification of production products.

Equipment composition of cement production line:

The entire cement production equipment consists of a crusher, a powder mill, drying, calcination, a series of cement production machines, an E-type crusher, a raw material mill, a rotary kiln, etc.

Process flow of cement production line:

1. Crushing and pre homogenization
(1) Crushing - In the process of cement production, most raw materials need to be crushed, such as limestone, clay, iron ore, and coal. Limestone is the largest raw material used in cement production, with a larger particle size and higher hardness after mining. Therefore, the crushing of limestone plays an important role in material crushing in cement plants.
(2) Pre homogenization of raw materials - Pre homogenization technology is the use of scientific stacking and retrieval techniques during the storage and retrieval of raw materials to achieve preliminary homogenization of raw materials, enabling the raw material yard to have both storage and homogenization functions.
2. Raw material preparation
In the process of cement production, for every ton of Portland cement produced, at least 3 tons of materials (including various raw materials, fuels, clinker, mixtures, and gypsum) need to be ground. According to statistics, the power consumption of the dry cement production line grinding operation accounts for more than 60% of the total power consumption of the plant, of which raw material grinding accounts for more than 30%, coal grinding accounts for about 3%, and cement grinding accounts for about 40%. Therefore, reasonable selection of grinding equipment and process flow, optimization of process parameters, correct operation, and control of operating systems are of great significance for ensuring product quality and reducing energy consumption.
3. Raw material homogenization
In the production process of new dry process cement, stabilizing the composition of raw materials entering the pit is a prerequisite for stabilizing the thermal system of clinker burning, and the raw material homogenization system plays the final check role in stabilizing the composition of raw materials entering the pit.
4. Preheating decomposition
Preheating and partial decomposition of raw materials are completed by preheaters, replacing some of the functions of rotary kilns, to shorten the length of the kiln. At the same time, the gas material heat exchange process is carried out in a stacked state inside the kiln, and moved to a suspended state inside the preheater, so that the raw materials can be fully mixed with the hot gases discharged from the kiln, increasing the gas material contact area, fast heat transfer speed, high heat exchange efficiency, and improving the production of the kiln system.
5. Burning of cement clinker
After the raw material is preheated and pre decomposed in the cyclone preheater, the next process is to enter the rotary kiln for clinker burning.
6. Cement grinding
Cement grinding is the final process in cement manufacturing and also the most power consuming process. Its main function is to grind cement clinker (as well as gelling agents, performance adjusting materials, etc.) to the appropriate particle size (expressed in fineness, specific surface area, etc.), form a certain particle size distribution, increase its hydration area, accelerate the hydration rate, and meet the requirements of cement slurry setting and hardening.
7. Cement packaging
Cement can be shipped in two ways: bagged and bulk.
