The cement powder separator has simple configuration and low cost, and can greatly increase the output of the mill. This product has a reasonable internal structure and good powder selection effect. It can improve the product quality of the grinding system after the implementation of new standards and lead a new trend of technological innovation of powder separators. So how does he work?
Cement powder separator, working principle of cement powder separator
Working principle of cement powder separator:
When the cement mill is working, the high-speed motor drives the vertical transmission shaft to rotate through the transmission device. The material enters the powder selection chamber through the feed port on the upper part of the powder selection chamber, and then passes through the upper and lower cones set on the medium-coarse powder collection cone. The powder guide tube makes the powder discharge plate rotate with the vertical transmission shaft. The material is affected by the inertial centrifugal force and the bulk material is evenly dispersed. Under the action of the high-speed airflow from the external fan entering the powder selection chamber through the air outlet, the coarse particles in the material are affected by the inertial centrifugal force. And throw it towards the wall of the powder selection chamber. After the collision, it loses kinetic energy and slides along the wall and falls on the coarse powder collection cone. The remaining particles are blown up and curled by the wind. When passing through the fan blade operating area, some of the coarse powder particles are thrown to the wall of the powder selection chamber. After the collision, It loses kinetic energy and slides along the blade surface, and is collected in the coarse powder collection cone.
After the medium-thickness powder passes through the fan blades, it continues to rise upward through the guide vanes under the action of the rising airflow and enters the secondary powder selection area. Under the action of the strong and stable plane vortex formed by the cage rotor, the air containing dust will throw the medium-coarse powder to the vertical guide vanes by centrifugal force, causing it to lose kinetic energy, enter the medium-coarse powder collection cone, and be discharged from the medium-coarse powder pipe. The fine powder enters the interior of the cage rotor through the cage rotor, enters the low-resistance cyclone separator with the circulating air, and then slides into the fine powder collection cone to become the finished product.
