introduction：Lubricating pairNSKbearing[NSKbearing:Seiko Co., LTD（NSK LTD.）Be established in1916years，It is the first manufacturer to design and produce bearings in Japan。NSKThe function of the bearing fit is to makeNSKThe stationary ring and rotating ring of the bearing are respectively the stationary part of the installation part(Usually a bearing seat)And rotating part(Usually an axis)Solidify together，Thus, the basic tasks of transferring the load in the rotating state and defining the position of the moving system relative to the stationary system are realized。]，Especially the fatigue life and friction of rolling bearings、wear、Temperature rise、Vibration and so on have important effects。There is no normal lubrication，

introduction：Working process The granular material is fed continuously and quantitatively by the feeder，The cold air is heated by the heat exchanger and enters the bottom of the fluidized bed，Penetrate the material layer through the distribution plate，Under the joint action of air flow and two high-frequency vibration motors, the material is highly dispersed and fluidized，Form a certain thickness of the fluid layer，Make sufficient heat and mass exchange between the air flow and the material，Rapid drying and dehydration，Due to the effect of vibration and the diffusion of materials，The material flows uniformly and continuously from the feed end to the discharge end of the fluidized bed，Finally, the dry material is discharged through the discharge port，Wet air is discharged from the top of the fluidized bed。
