Does not apply to transport perishable, viscous, easy caking materials. Screw feeder make up of trough, spirocheres, bearings and drive components. Spirochete is supported of both ends of bearings and the middle suspension of bearings, divern by the dive. Continuously Variable Transmission is adjusted motor speed by changing the frequency of AC, thus changing the speed. In the speed of the process, with the impact of small, gentle to exchange rate, it is an ideal high-efficiency and high-performance speed control means. It can meet the engineering requirements of the production and can also ruduce workers labor intensity, improve productivity, to achieve material handling process mechanization and automation. The design uses ideas and methods of optimization, through the feeder allows the complete design and calculation of transmission capacity and efficiency of a more reasonable match, transmission performance and transmission capacity of the main parameters of the analysis and use in the production and improvement of practical rationality. Subject to the design research methods of screw conveyor, theoretical analysis combined the performance of the machine to conduct a comprehensive, parameters of in-depth study. According to model selection, design parameters to determine the principles and methods of identification of aircraft for the LS-type screw conveyor. Optimization of spiral blades, combined with the actual completion of work objectives through the calculated use of R-bend helical sounded style blade, to determine the most reasonable fill factor that is feeding quantity, pitch size. With frequency converter or motor, so screw conveyor applications to improve productivity, improve quality, increase the degree of automation equipment.
