Blind hole press roll is suitable for the pressing process of paper dewatering and pressing. It has a large number of tiny blind holes on its surface. Its special design can effectively remove more water from the paper during the pressing process and maintain the quality and uniformity of the paper surface, reducing damage to the paper.
The blind hole structure can effectively absorb water during pressing. When the blind hole press roll contacts the paper surface, it absorbs its water and then discharges it by gravity or suction, reducing the water content of the paper and reducing the drying burden. Based on the blind hole design, the press roll will not leave obvious marks on the paper surface, ensuring that the paper is flat and can apply pressure evenly. It absorbs water through the holes, reducing the damage to the paper caused by excessive pressing. Compared with traditional pressing, it can effectively reduce the breakage of paper, which is particularly important when producing thinner paper grades.
(1) Efficient dehydration
(2) Make the moisture of wet paper uniform and reduce the blanket marks on the paper surface
Good wear resistance and stable hardness.
