Abstract:In this design, a security drum sieve in the production of quartz sand is designed in detail. The security drum sieve is composed with sieve roll drum ,main frame truss, parts of transmission and control system.Through the original data analysis, comparison and evaluation program on the analysis of the data, the overall design of the safety drum sieve is calculated. On this basis, the structure size of the trommel sieve，the shaft size,shaft coupling, decelerator is illustrated and calculated in detail. Description the design is based on what is the principles and how to design.The model possess advantages what simple in structure, the use of maintenance-friendly, high efficiency of sieving.
