Audited Supplier The stone roller is the main component of the pressing device. There are many types of stone rollers.The natural granite stone roller 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 roller has a smooth surface, but has many small pores and is breathable. The performance is good, 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.Wulong Rock Roll is the world's highest granite rock roll. This rock roll is formed by a pure natural magma erupted by a volcano.The manufactured paper has high tensile strength and high surface smoothness, and is favored by users all over the country. The service life of large-diameter stone rollers is as long as 15-20 years. Especially for high-grade tissue paper, writing paper, xerographic paper, cigarette paper, cow cardboard, and value-added tax invoice paper.
Because of the great difference between the ultimate strength of granite under tension and compression, the stone roller usually adopts a prestressed structure. The granite roller body is tightly pressed on the steel mandrel with nuts and washers with left and right threads respectively . This structure can reduce the tensile stress in the granite roller body. If the pre-compression stress is large enough, the stone roller body can only be subjected to compressive stress.
