1、 Product Introduction:
Produced by Wuxi Hushan Energy saving Technology Co., LtdHVX-The series of sand and gravel dewatering machines adopt non powered static technologyVA classifier composed of a shape selection machine and a fine powder collector, characterized by being composed of a fan, a coarse and medium sand dispersing and sorting device, and a fine powder collector; It is a static classifier that is completely dispersed by gravity and sorted by wind power. This device has a simple structure, sturdy components with a long service life, low air volume, and low pressure loss. The fineness of the finished product can be controlled by adjusting the air speed, and it is widely used for stone powder grading on highways. It can be used to separate non viscous and low moisture materials. In addition to being used in roller grinding systems, it can also be used in coarse grinding or other powder selection process lines.
2、 Construction and working principle:
The cyclone separator is located around the sorting chamber, and its inlet is connected to the upper part of the sorting chamber through a pipeline. The outlet of the cyclone separator is connected to the inlet of the fan through a pipeline. The outlet of the cyclone separator for collecting fine powder is located at its lower end; Non powered staticVThe shape selection machine consists of a feeding deviceVIt consists of a dispersing and separating device, a coarse sand discharge port, and a medium fine sand discharge port,VThe upper part of the shape selection machine is equipped with a feed inlet and a uniform fabric sealing device, with one end as the air inlet and the other end as the air outlet. The dispersing device is set from top to bottom in sequenceVInside the shaped tube and located on one side of the air inlet, the grading device is sequentially arranged from top to bottom inside the loose packing tube and located on one side of the air outlet. A feeding channel is formed between the dispersing device and the grading device,VThe bottom end of the channel of the shaped tube is equipped with a coarse sand discharge portVThe separation device of the shaped tube is equipped with a medium fine sand discharge port at the lower part of one side to collect and classify the medium fine sand;VThe inlet of the shaped tube is connected to the outlet of the circulating fan through a connecting tube,VThe air outlet of the shaped tube is connected to the fine powder collection device through a transition pipe-The inlet channel of the cyclone separator is connected.
Enter static stateVThe material of the shape classifier is fed into the upper feeding port, and the mixture is evenly dispersed and falls through the buffer of the material blocking and uniform distribution device. It enters the middle dispersing and grading shell, and in the grading area, the material particles flow through the dispersing grid inside the middle dispersing and grading shell and the grading device under the dual action of wind and gravity of the material particles. They are then discharged from the outlet of the air outlet shell. Due to the effects of airflow and gravity, fine powder is discharged from the air outlet and collected by a cyclone separator (or bag filter). Medium fine sand powder falls and is discharged through the middle medium fine sand powder discharge port (this port can be left open according to user requirements). Coarse powder is directly discharged throughVThe coarse powder is discharged from the discharge port of the shaped tube. Sorting relies on wind power to complete, and the fineness and material carrying capacity of the classifier are controlled by adjusting the air volume of the fan (frequency conversion adjustment).VThe particle size sorted by the static classifier is generally smaller than0.2Mm, and the particle fineness can be changed by adjusting the air volume and blade direction.
3、 Performance characteristics:
There are no rotating parts inside, mainly composed of grid plates arranged in a ladder shape. The materials to be sorted flow in a trapezoidal shape on a set of steps, and there is sorting airflow passing through the steps. The airflow separates fine powder from the material and transports it to the fine powder outlet. By adjusting the sorting airflow, the particle size distribution and flow rate of coarse and fine powder can be adjusted. Improved the stability of the powder selection machine, and the structure of the powder selection machine is simple, easy to install and maintain, with minimal wear and maintenance. Practical use has shown that the grading efficiency of this classifier is high, the fineness adjustment is convenient, the service life is long, and the performance is stable and reliable.
