Air flow screening machine

Horizontal airflow sieving machine is a high-precision screening equipment for mesh screening of fine powder. It is widely used in chemical, pharmaceutical, food, papermaking, metallurgy, building materials, rubber, machinery and other industries. It can continuously screen powdery materials with a fineness range of 80-500 mesh, and the screen mesh can be replaced at will. The air flow screening machine (air flow screen) has high screening efficiency, large output, accurate fineness, and no over-diameter mixing phenomenon. The screen is vertically installed without load and has a long service life. It can adapt to a wide range of fineness. It has a fully enclosed structure and no dust overflow. Dispersed, low noise, low energy consumption, continuous operation, and easy maintenance.

Horizontal air flow screen, the mesh is cylindrical and is placed inside the machine body. After the material passes through the screw conveyor system, it is mixed with the air flow and atomized into the mesh cylinder; the material is subject to centrifugal force and cyclone propulsion force at the same time through the wind wheel blades in the mesh cylinder. , so that the material is sprayed through the mesh and discharged from the fine material discharge port, and the material that cannot pass through the mesh is discharged from the coarse material discharge port along the wall of the mesh cylinder.

Features：

1. The air flow screening machine has high screening efficiency: it can reach more than 95%;

2. The output per unit is 5-10 times or higher than that of the vibrating screen;

3. Suitable for a wide range of fineness: powdery materials of 80-530 mesh can be quickly screened

4. The product has high precision and no super mixing phenomenon;

5. The air flow screening machine screen is installed vertically, is not load-bearing, and has a long service life;

6. The screening process is carried out under a negative pressure semi-circulation state, without dust pollution;

7. It can be used with various mills and air ducts connected to the grid;

8. Low noise, low power consumption, continuous operation, and reduced maintenance.

Application

Mesh number range: 80-530 mesh for screening and grading powdery materials of various shapes for 120-180 mesh light calcium, 300 mesh heavy calcium, 500 mesh iron oxide black, iron oxide red, 400 mesh active calcium, 300 mesh hawthorn powder, Used for screening materials such as 180-270 mesh quartz powder, 320-500 mesh zinc powder, 120-160 mesh Chinese medicine powder, etc.

Applicable materials are as follows: graphite powder, resin powder, Chinese medicine powder, paint, fly ash, talc powder, industrial drugs, cosmetics, fire extinguishing agents, plastic powder, clay, abrasives, aluminum powder, glass powder, refractory materials, starch, milk powder , metallurgical powder, electromagnetic materials, copper powder, carbon black, activated carbon, light calcium carbonate, iron ore, etc.

working principle:

The screen mesh of the horizontal airflow screening machine is cylindrical and is placed in the body of the cyclone screen. The screened materials are mixed with the air flow through the screw conveyor system, materialized and then enter the mesh cylinder. The materials then pass through the wind wheel blades in the mesh cylinder and are subjected to Centrifugal force and cyclone propulsion can cause the material to be sprayed through the mesh and then discharged from the fine material discharge port, while the material that cannot pass through the mesh is discharged from the coarse material discharge port along the wall of the mesh cylinder.
