Rotary Kiln Calcination Process

Rotary kiln means rotary calcining kiln. Commonly used in building materials equipment. Rotary kiln can be divided into: lime rotary kiln, cement rotary kiln, metallurgical chemical kiln, lime rotary kiln, limestone rotary kiln and so on according to different material types. The rotary kiln is a commonly used equipment in industrial production. Widely used in: chemical industry, metallurgy, building materials, ceramics, cement and so on. Analysis of the whole process from raw materials to finished products.

Rotary kiln calcination process:

1. Preparation of raw materials: the first raw materials are screened, usually used: clay, limestone, cement, quicklime, iron ore powder and so on. First of all, the raw materials for crushing, crushing, grinding and other processes. It is convenient for subsequent calcination and roasting.

2. Dosing and mixing: According to the needs of different customers. According to a certain proportion of raw materials for the preparation of ingredients. Immediately after the mixing equipment to fully configure and mix the raw materials. So that the calcination performance can reach the best.

3. Make into powder: the mixed materials through the crushing and grinding system. Then through the broken, drying, grinding and other processes. So as to make the powder that meets the requirements.

4. rotary kiln roasting: equipped with good powder through the rotary kiln for high-temperature calcination. Under the condition of high temperature and oxygen-free and oxygen-poor atmosphere. Chemical reaction occurs. Minerals are produced. The temperature and atmosphere of the rotary kiln during this calcination process are crucial for the production of the finished product.

5. clinker cooling: the calcined material clinker passes through a cooling system. The quality and properties of the clinker are guaranteed by the use of cold working devices. This guarantees the quality and performance of the clinker.

6. transport and storage: the cooled material is transported to the storage system for storage.

7. Finished product and packaging: the finished product is tested by a monitoring system. To ensure its quality and performance. Then it passes through the packaging system. Thus it is easy to transport and use.

The rotary kiln calcination process flows from raw material to finished product. The whole production line is also equipped with dust collection system and exhaust gas treatment system. Ensure that the waste gas generated during the whole process is treated and discharged according to the standard. Prevent pollution to the surrounding environment.
