The photo is an on line remanufacturing press roller

 Roller press came to the market since the mid of 1980s.the roller press and the ball mill combined the united grinding system or semi-united grinding system which has used widely in various grinding system.

Roller press has the following advantages:1,less power consumption,increased output. 2.better cement quality 3.less noisy.

Roller press also has it’s disadvantages,it’s biggest disadvantage is severe surface abrasion of the rollers.usually,the roller press runs continualy half an year ,after half a year the wear risistant part will completely worn out .

The master key to guarantee the life of the roller press is remanufacturing the surface of the roller press by overlaying in time,if the overlayed surface maintains well ,which can decrease the stop production time and fully express the advantages of the roller press in grinding syste.

In the past ,usually the cement factory use high chromium cast iron wear resistant strip,after overlayed such kind of resistant strip,the base part is made of iron,on the surface of the base part is carbide,the content of the carbon is more than 3%,the hardness of the overlayed layer is about HRC60.It’s advantage is wear resistant performance is superior.It’s disadvantages are bad combination,bad anti-crack,bad anti-fatigue,it appears crossed crackle flaw when overlayed one layer of such kind of material.

And because of the stress,such kind of roller press easily appear large scope of spalls,that is why we need remanufacture such kind of roller press every month. Meanwhile the cross crackle will affect the base part of the press roller,then the surface base part of the press roller appear defects,then the quality of the press roller is becoming worse and worse till the whole press roller destroyed.

ARC explored a kind of professional welding material to meet the special situation of the roller press,and combine the scientific overlaying procedure,relying on the above two conditon,the press roller can reach a satisfied effect,largely extend the life of the press rollr,decreased the remacufacturing times.
