introduction： Multiple bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The bearing steel used by enterprises is not good enough，Even some inferior bearing steel，This leads to the production of low bearing products，likeKOYObearing[KOYObearing:kOYOBearings are generally required to bear large loads，Often is not

introduction：Working principle Vacuum rake dryer uses steam jacket to indirectly heat materials,And exhaust under high vacuum,It is therefore particularly adapted to high temperature intolerance、Materials that are readily oxidized at high temperatures or that produce powders when dry，And the steam discharged during the drying process must be recovered from the material drying operation。The dried material is added from the top of the shell right in the middle，Under the stirring of the constantly turning rake teeth，When the material is in contact with the shell wall，Constant surface renewal，The dried material is subjected to steam（Or hot water、Heat transfer oil）Indirect heating，But the material moisture gasification，The moisture of the gasification is pumped away in time by the vacuum pump。The material being dried is indirectly affected by the heat carrier
