1. Crushing and Pre-homogenization.
(1) Concrete Crushing. 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.
(2) Pre-homogenization of raw materials. Pre-equalization
technology is to use the scientific stacker reclaimer 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 concrete 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.
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. Concrete 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 ball 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
concrete packaging. It's important to intact the chemical and physical
properties of the concrete for a longer period of time.
With its high quality products such as , , , , , Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
