Paper Machine Blind Hole Press Roll Rubber Coated

Blind Hole Press Roll Basis Information

A large number of holes with a certain depth are drilled on the surface of the pressure roller. The depth of the holes is best to use two or three different sizes of depths and the same arrangement. The bottom of the holes is not connected to the atmosphere or vacuum, so it is called a blind hole.

The pressing form consisting of blind hole press rolls is called blind hole press. Blind press roller is also hung rubber or polyurethane on the iron roller core. Blind holes with a diameter of 2mm and a depth of 12~15mm are drilled on the rubberized surface. Blind holes of different depths and two rows of alternate rows can also be drilled.

The opening rate of the blind hole press roller is about 25%~30%, and the hole volume is about 5 times larger than that of the groove press roller, so it can accommodate more Squeeze water.

The solid part of the blind hole pressure roller is not as easy to damage as the groove pressure roller, so the roller can be covered with a softer layer of about 70~90 Shore hardness. As a result, one is to reduce the wear of the felt, and the other is to provide a wider nip, which is beneficial to increase the pressure of the nip line. Compared with the grooved grooved roller with a groove depth of 2.5mm, the blind hole with a depth of 15mm can be ground many times more than the grooved roller before re-coating.

Blind Hole Press Roll Function

Dewatering in the press section, the main function of the press section is to dewater the fiber mat by means of mechanical pressure. The dry content is increased in the presses before the paper web is transferred to the dryer section. The higher the increase in dry content out of the press section, the less drying energy is needed. This makes the paper manufacturing process more efficient and cost effective. This is reason enough to make the dewatering of the paper web as efficient and effective as possible.
