I thought that U had asked this before and U got an answer???

Please refer previous threads.

Try Soudage and Vautid.

Hardfacing is crhomium carbides.

Why do U have a problem. U will always get wear??

Normally, hardfacing is done when:

power consumtion rises dramatically as the liners wear > loss of rate

wear rate is high and can not make kiln campaigns

I presume that U are also talking to magotteaux re liner materials etc.

I will let U do the homework

Thanks

The mill is being used for grinding of limestone mainly at a rate of 215 tonnes per hour. I would be thankful if anyone can tell me which type (composition) of hardfacing to use to reduce the wear rate. It will be of great help if the information regarding the company that does the hardfacing or the composition and process of hardfacing can be elaborated.

Also I would be thankful if any one can suggest me the new ways of maintenance of Vertical roller mills.

thanks in advance

Flux Cored Wires

(Brand: KX )

The Flux Cored Wire is used to restore parts exposed to difficult temperature and deformation conditions under cyclic and thermal effect. First of all, these parts are the hot and cold cutting knives, rollers, bandages, equipment for production of rings and bearings. It is also used for flux surfacing of metal forms, crystallizer rollers and other parts that occasionally come into contact with liquid metal (cast iron and aluminum alloys), surfacing of plungers of powerful hydraulic presses, exposed to abrasion wear and corrosion, surfacing of cylinders and other components of tube mill machinery and section rolling equipment, impellers, bushings, discs, mine lining sheets etc. ■
