一. Dahan brand vertical airflow screen machine Features:
1. High screening efficiency: it can reach more than 95%.
2. The output  wasmore  5-10 times than vibration screen.
3. Adaptation range: 80-530mm powder can be efficiently screening.
4. Product fineness is accurate, no super mixed-level phenomenon.
5. Screen mounted vertically, not weight-bearing, long life.
6. Screening program is runningin the negative half-cycle state, no dust pollution.
7. Low noise, low power consumption, continuous operation, reduced maintenance.
8. Vertical airflow powder materials have mesh filter grading, its high screening efficiency, large output, automatic feed nesting, continuous operation, no pollution, making it difficult in the past with a variety of high-shaker fineness precision screening operations become easy.
9. Vertical airflow sieve is suitable for all kinds of powder material. Its screening efficiency is high, large output, automatic feed discharging, continuous operation, no pollution. It makes the jod is easy.
10. After light calcium on 120-180 mesh, 300 mesh TSP, active calcium 400 mesh and 300 mesh hawthorn powder, 320-500 mesh zinc powder, 500 mesh black iron oxide, iron oxide red, 120-160 mesh in powder, 180- sieved using a 270 mesh quartz powder material, the measured output per hour per square meter screen area were about a ton, while the measured screening efficiency above 95%, the dust content of less than 10mg / m3.
