Our service:

1. Before sales, we will fully understand the customer's working conditions and recommend the most appropriate material selection to the customer.

2. Provide customers with drawings based on their machine models, spare parts dimensions, etc. 

3. After sales, we will continue to pay attention to the usage of the product and provide timely help.

If you need detailed technical information of the product or cannot find the product you need on the website, please email us(info@lyzhili.com), because we are a customized factory for roller press spare parts.

It is suitable for medium and fine crushing of materials with medium hardness such as limestone, slag, coke, coal and other materials in cement, chemical, electric power, metallurgy, building materials, refractory materials and other industrial sectors.

The roller sleeve can be replaced and surfacing repaired according to the customer's usage, so that customers can use the scrapped rollers again with the most economical and effective products and services. At the same time, new rollers can be made according to the customer's drawing requirements to provide strong support for meeting the customer's production needs.

Introduction to the production process of rollers and roller sleeves:

1. The new roller or roller sleeve is made of 35crmo or 42crmo steel forgings, and the thickness of the roller sleeve is not less than 220㎜ or the same as the original roller sleeve thickness.

2. The forged workpiece is quenched and tempered and flaw detected.

3. Machining rollers and roller sleeves to the composite drawing size requirements.

4. A 20㎜ thickness is reserved on the surface of the new roller and roller sleeve workpiece for surfacing.

The material of the roller press extrusion roller is 42CrMo and 35CrMo, which can be made according to the specific requirements of customers.

The base of the cladding roller is made of forged low alloy steel with high strength and good toughness. Then the surface of the base is cladding, and the circumferential insulation cladding is adopted circle by circle and layer by layer. The cladding roller surface patterns include one-line pattern, diamond pattern, circumferential wave pattern, herringbone pattern, etc. The roller sleeve has high surface hardness, wear resistance, appropriate inner hole hardness, convenient processing and inlaying, low cost, low price and long service life.

Introduction to the extrusion roller surfacing process:

1. Remove the residual hard layer and cracks on the roller surface. Use carbon arc air gouging to thoroughly clean the surfacing area of the roller surface, clean the residual hard layer, cracks, dust, rust, etc., and polish it to reveal the metallic luster.

2. Surfacing welding base layer. Use ZD1 welding wire for surfacing. Through the welding of the bottom layer, the uneven roller surface forms a relatively flat outer cylindrical surface, which is convenient for the welding of the buffer layer and the wear-resistant layer.

3. Use ZD2 welding wire to weld the buffer layer. ZD2 welding wire is a high-strength, medium-hardness surfacing material with good fatigue resistance and bonding, and at the same time has certain wear resistance, which plays a good bridge role between the roller body and the wear-resistant layer. Good buffer layer material selection and welding are important prerequisites for ensuring the safe and effective operation of the wear-resistant layer.

4. Use ZD3 welding wire to weld the wear-resistant layer. Pay attention to measuring the roller body size and roundness during welding, and weld until the roller body reaches the required size.

5. Finally, weld the wear-resistant horizontal bars. After the wear-resistant layer is welded, use ZD310 welding wire to weld the horizontal bars.
