introduction：As you know，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。]（Here mainly refers to rolling bearings）It is an indispensable basic component in contemporary machinery and equipment。Although its rise is less than a hundred years old，But because it is related to the national economy and peoples livelihood，All countries in the world spare no effort to develop their own bearing industry，Using advanced modern science and technology，

introduction：At present，More and more complex parts in the world are processed by composite machine tools。I recently visited the International Manufacturing Technology Exhibition held in Chicago, USA，It is found that the compound machining machine tool has become an important direction in the development of machine tools。Because the composite machining machine highlights that the workpiece completes most or all processing procedures in a single loading，Thus achieving a reduction in machine tools and fixtures，No handling and storage between processes，Improve workpiece machining accuracy，The purpose of shortening the processing cycle and saving the working area。 Several composite machining machines on display at the Chicago International Manufacturing Show，It basically represents the future development of the worlds machine tools

introduction：summarize： The material is fed into the stirring dryer by the screw conveyor，The hot air enters the dryer from the tangential direction of the feeding end and contacts the crushed material for initial drying，Under the dual action of stirring and air flow，The material moves backward and is continuously raised and crushed by the mixing claw，And exchange heat and mass with hot air。In this part，The material that is crushed to a small enough size dries first and flows away with the air flow，Relatively large material particles have high water content，Stay for a while longer，therefore，Stir dry parts even into them300~500℃Hot wind of，The material temperature will not be high。Behind the mixer dryer，The material is lifted by the double action of sheet and air flow
