Rotary Kiln for Cement Production Plants

We provide the full range service including design, manufacturing, installation for new type dry method cement production line with capacity from 50t/d to 3000t/d.

Process of Cement Production Plant:
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.

2. Raw Material Preparation
Mining of limestone requires the use of drilling and blasting techniques. 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.
We adopts advanced technology and equipment to improve the efficiency, technical level, advanced design, ensure the economical investment for the cement production line.
