We can provide you with various brands of Vertical mill roller/Grinding roller , also can customize and produce according to your working conditions

The most material of grinding roller is high Chrome,add the surfacing welding can extend lifetime and reduce costs and improve efficiency.Surfacing welding include Welding wire hard facing and Alloy studs inlaid surfacing welding.

Welding wire surfacing grinding roller improves the wear resistance and service life by surfacing wear-resistant welding wire on the surface of the roller body.

The Alloy studs inlaid surfacing welding vertical grinding roller is designed according to the working conditions and the wear resistance curve of the product. In the wear area, the powder metallurgy technology and surfacing technology are combined, and the special welding materials are used to form the inlay welding structure and metallurgical combination, improve the wear resistance and service life of the product, and achieve the regenerative repair to improve the service life of the product. This type of roller is suitable for extremely severe working conditions and can ｒｅｐｌａｃｅ the ceramic roller and other products on the current market.

We can not only provide users with reliable wear-resistant spare parts for vertical grinding and casting, but also have a professional surfacing team with excellent technology and rich experience. They can be operated on-line and off-line, and can provide users with satisfactory secondary welding.

Ceramic metal composite

Feature:

1. Possessing the characteristics of ceramics and metals

Ceramic alloy composite products combine the characteristics of ceramics and alloys. They have both the wear resistance of ceramics and the mechanical properties of alloys, and are not easy to break or fall off.

2. Surface honeycomb structure

Due to the different properties of ceramics and alloys, the height difference of the surface is caused, thus forming a honeycomb structure. This structure increases the friction force and effective contact area of the surface, which helps to improve the grinding or crushing efficiency.

3. Extend the service life of equipment

The hardness of the wear-resistant part matrix is ≥60HRC, and the wear resistance is good.

The working surface is reinforced with ceramic particles with a hardness of 1900-2100HV, which makes the surface have excellent wear resistance, thereby greatly improving the service life of the equipment. Under normal conditions, it can reach 2~3 times that of ordinary materials.

High chromium iron

Feature:

We use proper alloying and and related technological measures to make the blow bars’ surface hardness reaches more than 58HRC , during the process of wearing will maintain high hardness and high wear resistance.

Technology process

In blow bars’ working part we use the technique of directional solidification to make Cr7C3 type carbide is perpendicular to the part.The macro-hardness and micro hardness of carbide can be improved without reducing thoghness.

Application

Suitable for making wearable spare parts with lower impact load and simpler shape.

1：There are no exact corresponing value between rockwell hardness(HRC) and brine hardness(HB),so ,this two kind of hardness value can be inspend used 。 2：The hardness in the 40%deepness of casting section should be lower than 92% hardness of surface.

Medium alloy steel

Feature

The alloy structure cast steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloy elements on the basis of ordinary carbon steel.

Process technology

According to the different elements added, with appropriate smelting and heat treatment process to obtain high strength, high toughness, high wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other related special properties.

Scope of application

It is suitable for producing the wear-resisting spare parts with good mechanical strength and good toughness that are required for various working conditions, and the main steel structure castings with the required dynamic load.
