Concrete crusher is usually used in concrete crushing in the construction
waste dealing process. There are several series of concrete crushers during to
the crushing way, such as jaw concrete crushers, cone concrete crushers, impact
concrete crushers, vertical shaft concrete crushers and portable concrete
crushers.Concrete crusher 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. To sum up, the whole process includes 7 steps.
1. Crushing and
Pre-homogenization.(1) concrete crusher . During producing Concrete, most of the
raw materials must be first crushed before being used 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.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.(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.
(3)
Predecomposition. This process is featured with quality, efficiency and low
consumption, etc.5. The burning of concrete clinker.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.7. Concrete Packaging. What
you should pay attention to after producing concrete is Concrete Crusher Hire
packaging. It’s important to intact the chemical and physical properties of the
concrete for a longer period of time.Apart from excellent concrete
crusher, Hongxing Machinery's jaw crusher, impact crusher, cone crusher,
concentrator are also in good quality and advanced technology.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.
