&nbsp; &nbsp; &nbsp;</span><span style="font-size: 16px;">若TMR搅拌均匀度不合格,则根据影响TMR搅拌均匀度因子评分来提高TMR搅拌均匀度。</span></p> <p style="text-align: justify;"><span style="font-size: 16px;">&nbsp; &nbsp; &nbsp; &nbsp;</span><span style="font-size:16px;">a、检查更换TMR搅拌车刀片。</span><br /> <span style="font-size: 16px;">&nbsp; &nbsp; &nbsp; &nbsp;</span><span style="font-size:16px;">b、TMR搅拌时保证车体水平。</span><br /> <span style="font-size: 16px;">&nbsp; &nbsp; &nbsp; &nbsp;</span><span style="font-size:16px;">c、低质干草在做TMR前需预铡。(如国产燕麦草)</span><br /> <span style="font-size: 16px;">&nbsp; &nbsp; &nbsp; &nbsp;</span><span style="font-size:16px;">d、立式双搅笼TMR搅拌车,从两个搅笼中间位置加料。</span><br /> <span style="font-size: 16px;">&nbsp; &nbsp; &nbsp; &nbsp;</span><span style="font-size:16px;">e、加完最后一个原料后(包括水)搅拌3.5~5min后撒料。</span><br /> <span style="font-size: 16px;">&nbsp;

&nbsp; &nbsp; &nbsp;i、根据TMR搅拌车厂家提供工艺进行设定搅笼转速。<br /> &nbsp; &nbsp; &nbsp; j、立式TMR搅拌车正确使用助切刀(定刀),加干草时推入助切刀,帮助切短干草;所有原料加完搅拌时,拉出助切刀,搅拌均匀。</span></p> <p style="text-align: center;"><span style="font-size:16px;"><img src="http://www.cpmcd.com/uploadfile/2016/0127/20160127120929339.jpg" /></span></p>
