Granite Stone Roll 

The Stone Roll is an important part of the paper machine for pressing and dewatering. It has the characteristics of smooth surface, high hardness, high strength, acid and alkali resistance. The granite roll surface is smooth, but there are many small pores. Good air permeability, so the wet paper is easy to fall off, which is especially beneficial to the paper splicing operation, and is widely used in various paper machines.

 

Breast Roll

Usually, the breast roll is the first roller on the paper machine, which is the beginning of the wire table. One of its functions is to support the formed wire. The forming net changes direction on the breast roll, and after passing through the breast roll, the non working face of the forming net becomes the working face. In many cases, the breast roll is also a dehydrated part of the net table, and the pulp on the breast roll can remove part or most of the water.

 

Couch Roll

The vacuum couch roll on the fourdrinier paper machine is located at the place where the web of the forming fabric is removed, which is the end point of the working stroke section of the forming fabric. At the same time, it is an active roller wrapped by the forming fabric to drive the forming fabric to move.
In the cylinder paper machine, it refers to a pair of extruding and dewatering elements formed by the cylinder mould or the net drum, and the web paper layer is taken away by the wet felt.

 

Groove Press Roll

The structure of groove press roll is stone roller and rubber roller. The spiral grooves with width of 0.5-0.6 mm, depth of 1.0-3.5 mm and groove distance of about 3.0-3.6 mm are cut out on the rubber layer of the cot with alloy steel knife.
Compared with ordinary press, grooved press is easy to dehydrate, the linear pressure is lower and the thickness of rubber layer is increased. Therefore, the middle height of the roller can be reduced to avoid the high and uneven water content on both sides of the paper, resulting in the rib channel.
