【摘要】：试验旨在确定本锤片式饲料粉碎机筛片孔径、主轴转速和喂入量对粉碎后饲料几何平均粒度的影响关系及其成因。根据GB/T 17890—2008选用内蒙古包头地区种植的黄玉米,采用3因素五水平正交试验法,按试验要求分别选用4目、8目、14目、18目、30目孔径筛网,通过变频器设置1 600、1 900、2 200、2 500、2 800 r/min主轴转速,称取5、5.5、6、6.5、7 kg喂入量玉米,设计共25组试验,每组3个重复。试验所考察3个因素均对几何平均粒度影响显著(P0.05),其中筛片孔径对几何平均粒度影响较主轴转速和喂入量对饲料几何平均粒度影响明显。结果提示,在本试验设置范围内随着筛片孔径、主轴转速和喂入量的增大,几何平均粒度呈增大趋势。
[Abstract]:The purpose of the experiment was to determine the influence of the sieve aperture, spindle speed and feed quantity on the geometric average particle size of the feed after crushing and the causes of the influence. According to the GB/T 17890-2008, yellow corn was selected from Baotou area, Inner Mongolia. By using three factors and five levels orthogonal test method, 4 mesh 8 mesh 14 mesh 14 mesh and 18 mesh 30 mesh aperture screen were selected according to the test requirements. The main shaft speed of 1 600 Ma 1 900 2 200 Ma 2 500 t 2 800 r / min was set up by frequency converter, and the corn was fed with 5. 5. 5% 6. 6. 5 kg corn, and 25 groups of experiments were designed. The effect of three factors on the geometric mean particle size was significant (P 0.05). The effect of sieve aperture on geometric mean particle size was more obvious than that of spindle speed and feed rate on feed geometric mean particle size. The results showed that the effect of sieve aperture on geometric mean particle size of feed was more significant than that of spindle speed and feed rate. The geometric mean particle size increases with the increase of sieve aperture, spindle speed and feed rate.
