This is actually the second time my clients request me

why the wet pan mill paint rollers so costly almost the whole set.

I simply explain it and state that for that wet pan mill ready-mixed concrete batching plant,the paint rollers is an essential parts.

As you may know,the wet pan mill structure is straightforward,

just includes primary frame,paint rollers sicoma twin shaft mixer mobile concrete mixing plant,pan,basin and motor.

Primary frame is welded of steel plate and it is easy to get it done,

motor is all about $1000-1500 changes with energy

For that wet pan mill,

second costly parts is pan,about $1500-2000,

therefore it clear to see why the paint rollers are high cost,

Yet another point,

our wet pan mill paint rollers are constructed with whitened iron alloy

which material are extremely strong,put on-fighting off and also have lengthy service existence.
