Preheating the raw materials and decomposing partly

Preheating the raw materials and decomposing partly in pre-heater, which reduce the works of rotary kiln, can shorten the length of rotary kiln. After a series of physical process in the shorter rotary kiln, the energy consumption of this system improve the efficiency and reduce consumption.
(1) Dispersing materials. 80% heat transfer process happens in the entrance pipeline. The raw materials fed in pre-heater, meeting the high speed updraft, move up with the airflow and get dispersed.
(2) Gas-Solids Separation. When the airflow enters into cyclone muff with powder, it has to spiral and move down meanwhile. Finally, it arrives to the end of the cone then upwards and discharges from vent pipe.
(3) Predecomposition. The appearance of predecomposition is a leap of concrete burning technology. This process is featured with quality, efficiency and low consumption, etc.
5. The burning of concrete clinker.
Raw materials will be preheating and pre-decomposition in the cyclone preheater and then carried out into the rotary kiln for clinker burning. After the clinker burning, the temperature starts to fall. Finally with the concrete clinker cooler, the temperature of high-temperature clinker discharged from the rotary kiln will be cooled to the temperature which is suitable to downstream transport, store, and concrete. At the same time, the sensible heat of high-temperature clinker will be recycled, which improves the thermal efficiency and clinker quality of the system.
6. Grinding.
Grinding is the last process of concrete produce and also is the most current consuming working procedure. Concrete clinker get grinded into the right size. The smaller the particle size is, the better the final concrete is. There are many grinding machines suitable to grind the concrete clinker, such as ultrafine mill, vertical mill, high pressure suspension grinding machine and Raymond mill, etc. We will choose suitable grinding machine for you according to your requirements. With reliable quality and Certification authority, you can trust us.
7. Concrete Packaging.
What you should pay attention to after producing concrete is ultrafine mill Hire packaging. Its important to intact the chemical and physical properties of the concrete for a longer period of time.
