There are two common methods for roller crusher roller maintenance

The two round rollers of the roller crusher rotate mutually, and the ore enters into the space between the two rollers. As a result of the friction force, the ore is brought into the space between the two rollers and crushed. The broken product is discharged from the gap between two rollers under the action of dead weight. The minimum distance between the two rollers is the width of the discharge port, and the maximum particle size of the broken product is determined accordingly. There are two methods commonly used in roller maintenance: in-situ cutting (grinding) machining repair method and in-situ surfacing repair method.

1. Local surfacing welding

In - situ surfacing welding is to fill the worn notch. This method is simple and practical, does not affect the production, and the hardness and wear resistance of the surfacing welding parts are good, the disadvantage is only suitable for good weldability roller (such as cast steel roller). The following matters should be noted when surfacing:

In addition, the method of disassembly and repair can also be used, that is, the roller is completely disassembled with the shaft together, and is installed on the machine after repair by turning.

2, local cutting (grinding) processing method

Local cutting (grinding) method of operation is: in the crusher machine frame, install a special tool rest, its movement track should be parallel to the roller axis. When repair, start the crusher, with a manual feed mechanism (conditional can also use automatic feed mechanism) on the roller cutting. The following points should be noted when applying this method:
