How to Reduce Wear Rate on Mill Hopper?

02/16/2013 3:38 AM

Hi Guys,

We have a PUG mill agitating Nickel powder and the hopper is wearing out quite rapidly due to abrasive nature of powder. Can you guys suggest if some surface hardening will be helpful? The hopper is Mild Steel and the other option is change the material with stainless steel...

Any suggestion will be appreciated

Have hopper built out of AR 500 plate. We are having a simular issue and I just ordered the new one and it will be built of AR 500. There are lower grades of AR without as much abrasion resistance but all are better than mild steel.

You might get away with lining exsisting hopper with it.

Lining the hopper with UHMW-PE might work. (Sometimes elastomers are more resistant to abrasion than are hard materials.)
