Powder Machine MFJ40

Product Details:

When the powder machine is working, the materials entering the grinding area of the grinding disc are crushed by the impact column, and under the action of the suction of the induced draft fan, they go up and down along the two sides of the return circle and enter the separation area to be sprayed out from the material outlet through the fan separator. Due to the high-speed rotation of the fan blade separator, the centrifugal force generated hinders the passage of materials. When the particles are larger, the resistance is greater, and the material cannot pass through, and is forced to rotate back to the grinding disc to be crushed again. Only when the particles reach a certain fineness and the suction force of the induced wind is greater than the resistance of the fan separator, the material can be ejected from the pulverizer. Increasing the air volume of the induced draft fan and reducing the rotating speed of the fan blade separator can reduce the resistance of the material to go out and make the particle size larger. On the contrary, the particle size becomes smaller. Under the condition of constant wind pressure and fan blade separator speed, the mixture of material and air is evenly distributed in the separation area. Therefore, the material discharged from the pulverizer has a relatively concentrated particle size distribution.
