Product Description

Granite stone roller

1: Description

The natural granite press roll is an important part for dewatering on the paper machine. It has the characteristics of smooth surface, high hardness, high strength, and resistance to acid and alkali. The surface of the granite roll is smooth, but there are many small micro holes , Good air permeability, so wet paper is easy to fall off, which is especially conducive to paper receiving operation. It is widely used in various paper machines.

Manufacturing Standards:

Shell in seamless carbon steel pipe or steel rolling plate Cast iron hubs Alloy steel shaft Cast iron bearing housings Grease lubrication Covers in rubber, polyurethane, chrome layer, hard metal coatings

Three: matters needing attention

It is advisable to store it indoors to avoid roller cracks due to temperature changes in the open air, especially in cold regions.

Pay attention to protect the roller surface when loading the truck to prevent injuries and scratches.

Granite is a non-homogeneous material. It should be balanced in force during use to avoid vibration and tension.

During use, the temperature rise of the bearings at both ends does not exceed 40 degrees, to avoid the large temperature difference between the inside and outside of the roller caused by the excessive temperature, which may cause cracks on the roller surface or cause the core shaft and the roller to loosen and affect the use, especially the copper shaft or Babbitt shaft.

The linear pressure should not exceed 60KN / M (60Kgf / cm) when used under pressure.

 

The granite crushing roller end face is marked with a rotation arrow and must not be inverted during installation.

Application:
Stone Roll is used for quickly dewatering the press section of paper machine and adds the physical properties of paper.Material is natural marble roll body, carbon steel shaft head, and surface polishing treatment.
