求翻译：本部主要有定齿外圈、定齿内圈及动齿圈组成疏磨区域，浆料由主轴轴心线方向进浆，径向上方出浆口出浆。通过主轴进给机构使其做轴向移动（最大移动量为小于7mm），以调节定、动齿圈间隙，在开机时，其间隙为大于1mm，正常运行时不得小于0.50mm为适，在机壳下部设有排污孔，以备停机时清除剩浆及污物之用。是什么意思？

Headquarters are set outer teeth, inner tooth fixed ring gear and moving component wear sparse areas, the spindle axis line direction of the slurry into the slurry, the slurry above the mouth of the radial pulp.
