Parametric Design and Performance Characteristic of Isometric Curved Bar Plate Based on SEL and SSL

Curved bar plate is common used in the pulp refining, but its design method is rather vague due it complex shape. A design method of isometric curved bar plate using two main parameters, the starting point and bar angle of central curve, was proposed in this paper and the calculation of characterization parameters of specific edge load (SEL) and specific surface load (SSL) was described. Isometric curved bar plates designed by two methods, one with fixed starting point and various bar angles and another with fixed bar angle and various starting points, were analyzed by characterization parameters of SEL and SSL. It would be expected to design isometric curved bar plate by the first method and the SEL would be a useful refining intensity to measure it in actual refining, however, the refining characteristics of different isometric curved bar plates should be further studied. The study on the design of isometric curved bar plate would be conductive to the research of curved bar plate and rapid design of it. KCI Citation Count: 0
