Concrete is pulverized with the mixture of limestone, clay, and iron ore powder in proportion. At this time the mixture is called raw materials. Followed by calcination, the general temperature is of 1450 degrees. After calcination, the product is called clinker. Then according to a certain percentage, the clinker is mixed with gypsum. The mixture is then grinded to the required fineness. Here you have produced concrete. This is only a general description. Here you can learn about the whole process in detail.
In the process of new dry concrete 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.
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.Henan Hongxing portable mining equipment, rod grinder will be your best choice.

(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.
