振动筛可用机械方法或电力脉冲方法获得筛分动作,一般分为:偏心传动的振动筛、带不平衡重的振动筛、共振筛和电磁振动筛(图1——4) 各种振动筛的振幅可取0.38—25.4毫米(1/64—1时);物料沿筛面运动的速度可取3.04 8—24.4米/分(10—80呎/分);振动频率可取500—600周/分;筛分机的运动轨跡可以是圆、椭圆或直线。振动筛生产能力的确定鲍乌曼(V·A·Bauman)对下列因素进行了研究:振动的振幅和频率、筛面和筛孔的尺寸和形状、给料中筛下物的百分数、通过筛孔的筛下物的百分数、给料中含水 Vibrating screen Mechanical or electrical pulse screening method can be used to obtain screening action, are generally divided into: eccentric vibrating screen, vibrating screen with unbalanced weight, resonant screen and electromagnetic vibrating screen (Figure 1-4) The amplitude should be 0.38-25.4 mm (1 / 64-1); the speed of the material along the screen surface should be 3.04 8-24.4 m / min (10-80 ft / min); the vibration frequency should be 500-600 wpm; Extensions can be circular, elliptical or straight. Vibration sieve production capacity determination VA Bauman studied the following factors: vibration amplitude and frequency, the size and shape of the sieve and sieve, the percentage of sieve material in the feed, through the sieve The percentage of under-sieve material, water in the feed
