The efficiency can influent the fracturing operation directly. The HYPERLINK app:ds:operating \t operating HYPERLINK app:ds:principle \t principle of sand?conveyor is that sands can be sent to mixed sand tank car with its HYPERLINK app:ds:physical%20properties \t _self physical properties.According to the performance needed parameters, The purpose of this thesis is that how to confirm the HYPERLINK app:ds:spiral \t _self spiral HYPERLINK app:ds:diameter \t _self diamete and HYPERLINK app:ds:diameter%20of%20axle \t _self diameter of axle, and then conduct the HYPERLINK app:ds:design%20calculation \t _self design and calculation of the structural parameters of sand?conveyor, with the help of the needed parameters. The next step is to design screw shaft, HYPERLINK app:ds:screw \t screw HYPERLINK app:ds:blade \t blade, structure, connecting flange, holder, screw axis,front and back side structure, selecting the working life of bearing. Tester can optimize HYPERLINK app:ds:flanged%20shaft \t _self flanged shaft and the sealing and lubrication of HYPERLINK app:ds:bearing \t _self bearing, in order to sa
