At present, the domestic various screening machine generally exists in the productivity and the screening efficiency is low, has seriously affected the enterprises production. There are two ways to solve this problem: the use of screening new probabilistic selection and thickness selection and new screening machine. Investigation of the powdered material related physical and chemical properties (such as material composition, size distribution, viscosity, pressure and problems of the operating system, etc.), to determine the solution. Through the production process of powdered material characteristics is analyzed, and comprehensive consideration of production technology and technical requirements and safety prevention and some other factors, to design roller screening machine. According to the principle of kinematics, dynamics and screening of sieving machine screening function, the rolling of the sieving machine various agencies has carried on the detailed analysis and calculation of kinematics and dynamics, determine the gear, motor, coupling and sprocket, etc. The specific parameters. Rolling sieving machine generally consists
