Cement Clinker Grinding Station Introduction:
Cement clinker grinding plant (Clinker Grinding Station) acts as an individual production line in the last period of the cement production process. In the finished product period, the cement clinker is ground by adding moderate mixing materials and then transforms to the finished cement (cement Portland).
Cement Clinker Grinding Station Process:
1. Raw Materials
The main raw materials used in the cement manufacturing process are limestone, sand, shale, clay, and iron ore. The main material limestone is usually mined on site while the other minor materials may be mined either on site or in nearby quarries. Another source of raw materials is industrial by-products. The use of by-product materials to replace natural raw materials is a key element in achieving sustainable development.
2. Raw Material Preparation
Mining of limestone requires the use of drilling and blasting techniques. The blasting techniques use the latest technology to insure vibration, dust, and noise emissions are kept at a minimum. Blasting produces materials in a wide range of sizes from approximately 1.5 meters in diameter to small particles less than a few millimeters in diameter.
Material is loaded at the blasting face into trucks for transportation to the crushing plant. Through a series of crushers and screening, the limestone is reduced to a size less than 100 mm .
Depending on size, the minor materials (sand, shale, clay, and iron ore) may or may not be crushed before being stored in separate areas.
3. Crushing And Pre-homogenization.
Most of the raw materials must be first crushed before being used to make cement. These raw materials include limestone, clay, iron ore, coal and etc. Limestone is the largest amount of raw materials to make cement. According to the raw materials' different particles and hardness, there are many crushers used in crushing these raw materials, such as jaw crusher, impact crusher, cone crusher and vertical shaft impact crusher and etc.
4. Raw Material Homogenization.
In the process of new dry cement production, the stability of pit entry clinker raw material component is the premise of the whole system. Raw material homogenization system plays very important role in the stability of pit entry clinker raw material component.
5. Preheater And Calciner
Raw material preheating and decomposition is completed by preheater, which can improve the kiln system productivity and reduce heat consumption of clinker Purposes.
6. Cement Clinker Burning.
Raw material is carried out into the rotary kiln clinker for completion after preheating in the preheater and pre-decomposition.
7. Cement Clinker 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.
8. Cement Packaging.
Cement Clinker Grinding Station Specifications:
Cement Clinker Grinding Station Our Advantages:
1. High Efficiency
Cement grinding plant has high automation level, the operating process will adopt DCS central control system for adjustment, control and alarm in master control room, then the whole plant have less operator and also increase the working efficiency. The batching system have been adopt automatic quantitative feeding and measuring device, which have increase the material batching accuracy and also stablilizing the production’s quality.
2. Saving Energy
Adopting tube mill or vertical roller mill to producing qualify cement according to the raw material’s condition of clients. Producing system have adopt closed circuit to reduce the energy consumption of cement grinding. The single line scale can be from 15tpd to 1500tpd, which have been covered the cement factory’s different manufacture demand.
3. Environmental protection
Cement Clinker Grinding Station Adoption of High efficiency air classifier and pulse type bag filter have created the circumstance for energy saving and energy consumption reduction.
4. High degree of automation
There is no manual operation in the process of mill running, which realizes the automatic control with long-term, stable, effective, makes milling process more stable, realizes fine work of production.
