Fly ash dryer repair process axial movement adjustment: According to the working principle of the dryer and the structural characteristics and production experience in the maintenance of the dryer, fly ash dryer to ensure long-term safe operation of machinery and equipment, the key is adjust the roller. Maintenance dryer linear axis; so that the cylinder can normally be reciprocated in the axial direction, so that the gear wheel does not turn or remain stationary for a short little movement by force, so that each gear wheel, roller bear barrel more evenly body load. Adjustment method: observation wheel with the relative position of the idler is still in the middle position; brick molding machine gear wheel force and rotation. Roller adjustment should be based on the rotation direction of the cylinder, adjust the centerline of the idler take towards one direction while skew roller, and the formation of tiny cylinder centerline angle (usually not more than 0.5 °, in order to avoid ground profiled roller ) produces spiral upward thrust, channeling it with the barrel up and down the power balance, so that the cylinder running in a relatively stable position, which is in the tire, ran back and forth freely between the lower gear wheel. Heat and mass transfer properties of fly ash dryer equipment is: For pure convection drying constant drying phase, the surface temperature of the material is wet air wet bulb temperature. Heat transfer coefficient and mass transfer coefficient constant drying phase temperature state phase side is constant. In the falling rate drying stage, the drying rate of the dryer controlled by the internal conditions, the drying rate decreases, the material temperature rising, so the heat transfer coefficient and mass transfer coefficient of gas is changing. For fluidized bed, spouted bed, rotary drum dryers and other bulk materials used in dryer dryer, because the actual interfacial area involved in heat and mass transfer should not be accurately calculated, sometimes using the volumes that pass coefficient calculation more convenient, to ensure that the overall volume transfer coefficient can be measured by the method OK.
