The Theoretical Analysis of Cylinder Screening Machine Based on the Method of Mogensen Screening and the Design of Intelligent PLC Control

摘要

The process of the single particle through screening is researched theoretically with Mogensen screening principle. The screened particles are divided into "particle easy to screen" and "particle difficult to screen" according to the relative size and shape. Systematically analyze the factors that affect the efficiency of cylinder screening machine - the characteristics of materials' dimension, shape features, the movement of sieve, and sieve surface obliquity, in order to realize the nuts and kinds of nuts to be graded effectively according to the size and shape. PLC intelligent control is adopted into cylinder screening machine, through the real-time detection of the speed of the cylinder at all levels and the chain transfer between the cylinders, to logically estimate the possible faults in the screening process, improving the degree of automation and reliability and safety of the equipment operation.
