Granite press roll | Stone roll for paper machine

1. Introduction Natural granite press roller is an important part of pressing and dehydrating on papermaking machines. It has a smooth surface, hardness, strength, and acid and alkali resistance. The granite roller surface is smooth, but there are many tiny micropores, and the air permeability is good, so the wet paper is easy to fall off, which is particularly conducive to paper splicing operations and is widely used in various papermaking machines. 2. Main parameters *Specifications: diameter 300-1250mm, length 1-5 meters. *Model: 787, 1092, 2880, 1575, 1600, 1760, 1880, 2100, 2362, 2400, 2640, 3150, 3600, 3800, 4500. *Compressive strength more than 98.07MPa; Hardness HV more than 300; *Tensile strength more than 5MPa; *Elastic modulus more than 0.4X1000000kg/cm2.
