The detailed processing course of the concrete

The proposed 19-acre center for concrete, steel, yard waste and other materials would have a machine that crushes concrete that would be about 350 feet from Colton Meadow, a complex of 72 recently renovated Lakeland Housing Authority apartments at 1919 10th St. Housing Authority Executive Director Herbert Hernandez called the proposed business an 'uncovered dump.'

1. Crushing and Pre-homogenization.

(1) concrete jaw crusher

During producing Concrete, most of the raw materials must be first crushed before being used to make concrete. Among these raw materials which include lime stone, clay, iron ore and coal, etc. the lime stone is of the greatest usage to make concrete. With comparatively larger particles and higher hardness, crushing the lime stone to required fineness after mining is of relatively important consequence among crushing all those raw materials. There are many crushers used in crushing these raw materials, such as jaw crusher, impact crusher, cone crusher and vertical shaft impact crusher, etc.

2. Raw Material Preparation.

It takes at least 3 ton materials (including raw stuff, fuel, clinker, compound and gypsum) to produce 1 ton Portland concrete during the production. According to figures, the traditional type dry process concrete crushers of clinker consumes more than 60% energy of the whole factory. So the choice of grinding machines is very important.

3. Raw material Homogenization.

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.

4. pre-heater and calciner.

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.

• 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.
• 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.

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.
