The 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.  There are mainly two types of stone rollers as per material difference: the natural granite and imitation stone rubber stone roller. 

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. 

Imitation Stone rubber roller is mixed with special grade synthetic rubber material and nano-grade filling material. It has good paper peeling performance and unconventional wear resistance. It can be used with a scraper and can meet the harsh application environment of high line pressure. The imitation stone rubber roller has high hardness, good paper making and release performance, impact resistance, abrasion resistance, acid and alkali corrosion resistance and high production efficiency. It is an ideal substitute for natural stone roller and has good social and economic benefits.
