Analysis Of Pressure Operation Of Raymond Mill

2017-04-12 11:07:20

The air blower will encourage people to raymond mill, the air flow is material, powder, raised suspension shaft roller suspension movement, movement of the blades, the wind screen pipe resistance, pressure gradually by the positive pressure turn negative. Mixed airflow raised powder particle and gas into people's Congress cyclone separator, powder by cyclone separator is separated into the bin, to further reduce the airflow pressure, airflow powder particle separated by a blower to encourage people to Raymond mill, circulating air flow in closed system.

The air flow in the circulation system around the pressure is different, is always changing, Raymond Mill powder system air volume and wind pressure are shown in Table 3 - 2, running throughout the pressure distribution in Figure factors inside the mill wind pressure are:

  • 1. mill material at the bottom of layer thickness;
  • 2. feeding amount size;
  • 3. the grinding speed;
  • 4. analysis of rotational speed and blade angle machine.

The so-called zero pressure level, it is the air pressure in the system is zero pressure boundary points. Loop flow system in a total of two zero today, one in the blowers, air negative pressure by turn positive pressure interface, blower pressure is basically stable. Another zero interface in Raymond mill, air stream to a positive pressure to negative pressure interface.
