Abstract: Scatter grading device is the new blank cake which is published at the beginning of the 90's hits the divergence to choose the equipment, the aggregate cake to scatter with the size grading in a body, with the extruder necessary use, it may eliminate the disadvantageous influence extrusion grinder edge funnel and opens in when the engine off process and the normal work the big pellet which fully extrudes to the following grinding system has not been produced, which obtains the effect of the large scale production increase energy conservation. Scatter grading device carry on using the centrifugal impact crash principle to the material scatters, to disperse the shape realization graduation using the inertia and the aerodynamics principle.
In order to improve the grinding process system extrusion production, will more grinding work moved to the ground by extrusion scattered for loop, improve the grain size and material into the grinding mill sex, the subject of cement griding system design in grinding follow-up equipments scattered extrusion sorting machine. The whole machine by whole grade machine scattered compact design method, reduce the occupy space, and improve the efficiency of the scattered and classification. According to the classification of the machine work requires scattered, the process of the high concentration of principle, determined the classification of the whole machine scattered transmission scheme, the application of optimization methods set the speed of the rotor disc and scattered, calculating the system of sport and dynamic parameters determined the transmission. The choice of the motor, with the design of the shaft, wheel shaft structure design, the intensity, key link choice calculation, rolling bearing type selection, bearing life code calculation, the choice of the coupling calculation. On the basis of this project was the design improvement, will double drive apart, so the design of optimized shaft, improve the stability of the system.
