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.'
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.
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. According to the raw materials different particles and hardness, there are several suitable crushers which can be used in the crushing.
(2) Pre-homogenization of raw materials. Pre-equalization technology is to use the scientific stacker reclaimed technology to realize the initial homogenization of raw materials, so that raw materials yard has the functions of storage and homogenization at the same time during the process of the retention of raw materials.
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
ultrafine mills 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 claimer.
