Additional Information Of Cement Production Line

Preheating and Decomposition

Preheating and Decomposition

Instead of part function of rotary kiln, the raw material preheating and parts of decomposition is completed by preheater to shorten the length of kiln. At the same time, it makes gas materials heat exchange process in accumulation state in the stove move to preheater in inner state of suspension to make raw material with exhaust hot gas fully mixing. This increases the contact area between gas and raw material, heat transfer speed gets fast, heat exchange efficiency is high, can realize the purposes of improving production efficiency and reducing the heat consumption.

Pyroprocessing

When it finishes the preheating and decomposition of the raw material, next procedure is putting raw material into rotary kiln to burn into clinker.

The carbonate further quickly decomposes and in a series of solid phase reaction in rotary kiln and it generates minerals of cement clinker. With material temperature rise, the minerals will become liquid and generate large amount clinker. After clinker is burned, the temperature begins to reduce. Finally the cement clinker cooling machine cools the clinker discharged by rotary kiln to the temperature which downstream cooling conveying, stores and cement mill can bear. At the same time it recovers the sensible heat of clinker, and improves the thermal efficiency of system and clinker quality.

Cement Grinding

Cement grinding is the last process of cement manufacture, and it is the process that consumes most electric. Its main function is grinding cement clinker (and gelling agent, performance adjusting materials, etc) to the appropriate granularity, form certain particle gradation, and increase its hydration area, accelerate hydration speed, to satisfy the slurry condensation and hardening requirements.

Packing and Distribution

The cement can be distributed in package and bulk. Now national standard requests that bulk must achieve 70% above, so it is a big trend to develop bulk cement in domestic.

Henan Hongxing Mining Machinery Co., Ltd. is one of the most famous cement production line manufacturers and suppliers. Welcome to visit Hongxing Company.
