The table roll is a traditional dehydration part of the net, and also plays a role in supporting the net.It is a kind of thin-walled tube roller, which is made of seamless steel pipe, copper pipe or aluminum pipe. Rubber is also hung on the surface of the roll to improve its wear resistance and corrosion resistance, to facilitate the dehydration of pulp and to reduce the wear of the forming net.
Application
Dewatering and support wire mesh
Requirement
Light weight, flexible transmission and enough rigidity.
Features
The table roll is a kind of common thin-walled steel pipe roll. The surface of the roll body is coated with rubber, which is conducive to the dehydration of slurry, anti-corrosion and reducing the wear of copper mesh. Glass fiber reinforced plastic is also used to reduce weight.
1.The table roll is a kind of common thin-walled steel pipe roll. The surface of the roll body is coated with rubber, which is conducive to the dehydration of slurry, anti-corrosion and reducing the wear of copper mesh. Glass fiber reinforced plastic is also used to reduce weight.
2.The roller diameter mainly depends on the required dewatering capacity, which is generally 80-325mm. The higher the speed and the larger the width, the larger the diameter of the roller.
3.In structure, it is required that the roller should be light in weight, flexible in rotation and have enough rigidity.
4.In the paper machine with very low speed, especially when using sticky pulp with slow dehydration, the arrangement of the roll is first dense and then sparse, so that the pulp will be dehydrated more immediately after being put on the net, so that the paper sheet can be initially formed quickly and the occurrence of re flocculation can be avoided.
5.In the paper machine with high speed, the arrangement of the roll is usually in the way of first thinning and then densification or first thinning middle density and then thinning. The main purpose is to keep the pulp stable at the initial stage of the web surfing and avoid the excessive loss of fine fibers and fillers.
Groove table roll
When the speed is high, the groove table roller is often used to replace the top roller. In this way, the dehydration can be relaxed and the paper sheet can be evenly formed. It is generally considered that the wider the groove is, the lower the dewatering capacity is. The dewatering capacity of the grooved roller is only 1 / 2 - 1 / 10 of that of the ordinary roller.
