摘要
介绍了一种新型振动破碎机的结构与工作原理,对破碎机主要工作参数(主轴转速、振幅、板辊间隙与颗粒直径)的影响与选择范围进行分析。同时基于振动破碎能耗检测装置,以板辊式振动破碎试验机对各主要工作参数进行正交试验,以破碎分维数与破碎能耗作为因素指标,对试验结果进行破碎效果与破碎能耗的极差分析,得到最佳破碎效果下最优试验方案:主轴转速为25 r/min,振幅为6 mm,板辊间隙为24 mm,颗粒直径为24 mm;最低破碎能量消耗下的最优试验方案:主轴转速为8 r/min,振幅为2 mm,板辊间隙为16 mm,颗粒直径为30 mm。结果表明,振动破碎试验所得其工作优化参数,为振动破碎设备的结构优化与振动破碎设备的节能降耗提供数据支持。
The paper analyzes that the influence and range of selection for several main working parameters （spindle speed, amplitude, plate cylinder gap, particle diameter）on the crusher, and the structure, working principle of a new type of crusher vibration have been introduced. The range analysis crushing effect and fragmentation energy based on vibration broken energy consumption detection device, with plate roll crusher vibrating test machine for the main operating parameters of orthogonal experiment, to break the fractal dimension and fragmentation energy as a factor index. The results show that optimal test program under the best crushing effect is： spindle speed for 25 r/min, amplitude for 6mm, nip plate for 24 mm, particle diameter 24 mm ; The program under the lowest energy consumption broken is ： spindle speed for 8 r/min, 16 mm, particle diameter for 30 mm. A object function is provide data support structural optimization and energy saving. amplitude for 2 mm, optimal test nip plate for for vibration crushing equipment
