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°

Warning signs
In this manual you will find the following signs which indicate a potential hazard, which can or will cause personal injury or substantial property damage. Depending on the probability if the hazard, and how serious the injury or property damage could be, there are three levels if classification.
Warning sign (warning triangle) | Draws attention to the hazard |
Signal word | Identifies the degree of hazard |
Type of risk | Specifies the type or source of the hazard |
Consequences | Describes the consequences of non-compliance |
Precautions | Specifies how the hazard can be prevented |
Warning sign, signal word | Meaning |
 | Indicates a dangerous situation which will cause death or severe personal injuries if not avoided. |
 | Indicates a dangerous situation which may cause death or severe personal injuries if not avoided. |
 | Indicates a dangerous situation which may cause minor or medium personal injuries if not avoided. |
 | Material damage: the product or its environment could be damaged. |
