There are several kinds of mesh grooves for small papermaking machinery and equipment


What is the mesh slot of a small paper machine? The groove structure of a circular net paper machine is usually made of wood. The main part of the groove ring is sometimes lined with metal (usually stainless steel) and sometimes with plastic material. The so-called groove ring refers to the annular gap between the surface of the cage and the semi-circle. The groove ring must be carefully constructed and its shape must be symmetrical and smooth.


Network slots come in many forms. The longest service time is downstream slot and countercurrent slot. At present, movable arc plate mesh trough, dry mesh trough, rotary forming machine and drum vacuum forming machine are widely used in China, while pumped circular mesh is used in advanced paper machine.


The structure of grid groove has a great influence on the yield and quality of paper. All kinds of reticulation have certain characteristics. These characteristics may be beneficial to the production of one kind of paper, but may not be important to another. The mesh groove should be designed or selected according to the specific production requirements. The General requirements for the design of the groove structure are: the fibers in the groove are evenly dispersed without caking; the slurry in the groove has uniform flow speed in width; the channels of the groove are smooth and straight, and the rotation angle should be smooth to prevent the slurry from sinking; and it is easy to clean and maintain.
