On-site Surfacing Repair for FTM Compound Crusher

Compound crusher is a kind of frequently-used machine. To repair the roller drum of compound crusher, there are two ways: on-site cutting repair and on-site surfacing repair. Now, let’s see the latter one. What is on-site surfacing repair? It means to weld the concave with filling materials. This way is simple but practical.

What’s more, it does not influence the production. Hardness and wear resistance of welding parts are relatively good. But, this way is only suitable to those roller drums with good weldability. During the welding process, we need to notice several details. Welding rod should be D256 and D266.

To the welding rod with small diameter, we weld it with small current and in layer. By doing so, we can decrease the thermal stress and protect the welding parts from being seriously deformed or cracked. To ensure the size be qualified, we should often check the welding parts with ruler. Bonding of electric welding machine should be directly put on roller drum, not roller axis.

By doing so, we can protect the bearing and raceway from being burned when current flows away. Compound crusher enjoys the features of simple structure, reliable operation, low manufacturing cost and easy adjustment on particle size. It is mainly used for the secondary or tertiary crushing process.

By concluding the right operational behaviors and regular maintenance points, this paper is worthy to being recognized as good reference. Download the price list directly from our website!
