Rotor stator temperature

[Johno1]

we are spraying shotcrete in Australia with a D8-2 rotor stator and it seems to be getting very hot, could anyone tell me what is an expected temp range for r+s in general please? (we are spraying about 6 tonne per day)

The D8-2 is for a 380-400rpm machine, friction causes the heat obviously, aggregate sharpness creates friction, if the R+S is a twister it's pre set pump pressure is tight, try one with adjustable jacket and set to 8-10 bar is my best guess.

Thanks very much, appreciate the advice

Just what I was thinking.

I guess it's hot in Australia mate

No, we are 200 - 300 m underground
