Table Roll
Structure: The table roll is made of seamless steel tubes, covered with hard rubber. In order to facilitate the dewatering of slurry, anti-corrosion and reduce the wear and tear of copper mesh. There are also wrapped fiberglass, which is conducive to reducing the weight.
Diameter: Mainly to ensure that the roll body has sufficient rigidity and speed stability, so with the speed of the paper machine and the width of the relevant, the higher the speed, the larger the width, the case of the roll diameter must be larger, but also must be made of dynamic balancing calibration.
Scope of Application:
The table roll is used in low-speed paper machine, when the speed of the paper machine is higher than 300m/min, the pulsating vacuum suction generated by the table roll will interfere with and destroy the fiber layer that has been formed on the web. Instead of the grooved table roller, will reduce some of the pulsating suction. When the speed of 600m/min, no longer use the table roller, and use other dehydration components instead . When the wet paper passes through the table roll, it undergoes two vertical pulse changes, which cause disturbances in the paper stock, which have an important effect on the forming and dewatering of the paper sheet.
a. For low-speed paper machine, this disturbance is relatively gentle, can promote fiber dispersion, reduce fiber flocculation, on the page forming benefits;
b. For high-speed paper machine, the case of roll pulse action produced by the disturbance is too strong, the formation of a strong wash-out effect, the dewatering of paper and forming is not conducive;
Arrangement of case rolls:
Low-speed paper machine: first dense and then sparse.
High-speed paper machine: first sparse and then dense or first sparse in dense and then sparse.
Function: The table roll is to support the forming network, in the process of forming the network, giving the paper layer on the network with a pulsating vacuum suction force, prompting the dehydration of the paper material and produce disturbances, so that the fiber dispersion, to improve the formation of the paper sheet.
Grooved Table Roll
Structure: The same as the ordinary table roller, only the surface of the roller body on the car has a number of parallel ring grooves.
Function: At higher speeds, close to the breast roll of several table rollers are often replaced by grooved rollers. This can make the dehydration moderate, conducive to the uniform molding of the paper. It is generally believed that: the wider the more grooves, the lower the dehydration capacity, groove roll dehydration capacity of only ordinary case roll 1/2-1/10.
