That is a good question, from memory it was not that fast. i would have thought it was in the order of 2-3 revs per second or 1-200 per minute.
Be careful putting too much power in, the chassis is not that strong. They need a constant feed so the rollers are not touching, but not too much to strain the machine.
Ours used to run off an electric motor I am sure it was no more than 5hp and could have been a lot less
Was 60 years ago so memory is not that great.
Ours cracked the frame and we bought an Alvan Blanch mill mixer
I think you have a plate mill, not a roller mill. We had a Bentall XRSE roller mill with ornate castings that died of fatigue. It replaced a dirty MH hammer mill and was superceded by a yellow Bamford bruiser unit.
There is a similar crusher here . Bamford 4C is on it . Hasn't worked since the 1980s , when I bought a Fraser 7 " roller .
The pulley on ours was on the end of the shaft , on the outside of the flywheel . Originally it was driven by the belt pulley on a Fordson E27N TVO . In latter years it was driven by pto belt pulley on a Fordson Dexta . Belt pulley speed was not measured in rpm but in feet per min .
