General
As the rubber roll mills are manually operated the time to stop the rolles is of utmost importance.
Stopping of the roll can be calculated according to following:
φ | Stop angle | ° |
n | Speed | rpm |
Jmachine | Moment of inertia machine | kg\u2022m2 |
Jmotor | Moment of inertia motor | kg\u2022m2 |
Ts | Specific torque | Nm/bar |
Δp | Pressure over motor | bar |
ts | Response time hydraulic valve | s |
φ = (π\u2022 n2 \u2022(Jmachine + Jmotor)/(10 \u2022 Ts \u2022 Δp)) + 6 \u2022 n \u2022ts
Example:
CB400 typical application for a rubber roll mill
n = 15 rpm
Jmachine = 350 kgm2
Jmotor = 18.3 kgm2
φ = (π\u2022152\u2022(350+18.3)/(10\u2022400\u2022350))+6\u202215\u20220.15=13.7°
