SZZ系列自定中心振动筛工作原理
Working principles
自定中心筛的皮带轮几何中心与轴孔中心不同心，二者偏离一个偏心距a，a布置在皮带轮轮几何中心与偏心重块相对的一侧。当偏心质量向上运动时，离心惯性力向上，由于运动滞后于激振力180°相位角，故此时筛子向下运动。装在筛箱上的轴当然也向下运动。此时皮轮几何中心位于轴的上方a处，当偏心质量向下及筛箱向上运动时，轴向上运动，而皮带轮几何中心又位于轴的下方a处。所以，固定于筛箱上的轴是随筛箱一起运动的。
Since the fixed center screen pulley geometric center and the shaft hole center different heart, both from an eccentricity. A, a decorate in the center of the pulley wheel geometry and eccentric block is relative to the side.When eccentric quality upward movement, centrifugal force up, due to the movement lag the exciting force 180 ° phase Angle, therefore the sieve downward movement.In a sieve box on the shaft, of course, also downward movement.The skin round geometric center located at the top of the shaft of a place, when the eccentric quality downward and upward movement screen box, shaft upward movement, and pulley geometric center is located in the axis of a place below.So, is fixed on the screen box axis motion with screen box.

SZZ系列自SZZ系列自定中心振动筛技术参数表
Parameters
注：表中处理量是依据松散密度0.9t/m3的煤，按上层筛面最大和最小筛孔进行干式分级给定的，物料中小于筛孔尺寸之半的颗粒含量占40%，大于筛孔尺寸的颗粒含量占25%，筛分效率为90%。表中凡重量低于2t的筛机最大拆分件均没列出。
Note: The capacity is based on loose density of 0.9 t/m3 of the coal, according to the minimum and maximum mesh on the upper screen surface dry classification given, material in less than half of mesh size of particles content accounted for 40%, is greater than the screen hole size of particle concentration 25%, screening efficiency is 90%.All that weight in the table below 2 t the biggest screen resolution are not listed.
