现有预粉碎牵引对辊作用于单位幅宽浆粕上的沟槽数量为16~28个,沟顶宽大于25mm,沟底宽大于15mm,沟距(相邻沟顶中点与沟底中点的距离)大于45mm,沟高(沟顶与沟底的垂直距离)大于10mm,辊径(辊最小处的直径)大于135mm,槽角(相邻两个沟槽坡之间的夹角)大于40°。在对辊长度一定时,沟槽间

The number of grooves on the existing unitized pulverized pulp is 16-28, the width of the groove top is larger than 25mm, the width of the groove bottom is larger than 15mm, and the groove pitch (the midpoint between the adjacent groove top and the groove bottom (The distance between the points) is greater than 45mm, the height of the groove (the vertical distance between the groove top and the groove bottom) is larger than 10mm, the diameter of the roll (the minimum diameter of the roll) is greater than 135mm, Greater than 40 °. In a certain length of the roller, the groove between
