How to choose concrete mixer？
The concrete mixer has the characteristics of large working pressure, large flow, high production efficiency, convenient operation, safe and reliable, flexible movement, compact structure and depressive maintenance. In construction, it is used for horizontal and vertical conveying of mortar or large area spraying.
In highway road maintenance, grout filling for cement pavement collapse. In the prestressed component engineering, it is used for mortar injection expansion and the like. In the water project, due to the reinforcement of the dam. It is used for grouting and slope protection in national defense and civil air defense projects and mine tunnel construction. Used in coal-fired power plants to transport pulverized coal mortar. In the chemical and paper industries, slurry raw materials and waste materials are transported. Used in the maintenance of blast furnaces and other equipment in the metallurgy, steel and other industries. There are too many types and types of mixing stations on the market, so how should users choose?
The mixer has two types of circulating operation and continuous operation according to the operation mode.
The three processes of feeding, stirring and unloading in the circulating operation mode are carried out at regular intervals, that is, mixed in portions.
Since the various materials of the mixing are accurately weighed, the mixing quality is good. Most of these types of work are used.
The above three processes of the continuous operation type are continuously performed in a long cylinder. Although the productivity is higher than that of the cycle type, the mixing ratio of the materials and the stirring time are difficult to control, so the stirring quality is poor. Use less.
According to the stirring method, there are two kinds of self-falling stirring and forced stirring. The self-propelled mixer puts the mixture in a rotating mixing drum. As the drum rotates, the blades in the drum raise the mixture to a certain height and then freely scatter by its own weight. This is done repeatedly, until it is evenly mixed. This type of mixer is generally mixed with plastic and semi-plastic concrete. The forced agitator is a stirring drum that is not stirred by the blades that are evenly placed on the rotating shaft in the drum. The mixer has good mixing quality and high production efficiency; however, the power consumption is large and the blades are worn quickly. Generally suitable for mixing dry hard concrete.
The mixer can also be divided into fixed type and mobile type according to the device. . According to the discharging method, it is divided into two types: tilting type and non-tip type. The tilting type is dumped by the stirring drum, and the dumping is reversed by the stirring drum.
According to the mixing capacity, the concrete mixer can be divided into three types (mixing capacity 1000~3000L), medium type (discharging capacity 300~500L) and small three types of mixers.
The customer can choose the concrete mixer according to the size of the project and the material of the mixture.
