DC Motor Torque/Speed Curve

31 Torque/Speed Curves 32 Power Curv NOTE Key terms Torque also called a moment is the term we use when we talk about forces that act in a rotational manner You apply a DC motor power vs torque curve Up to Contents

The critical speed of the mill c is defined as the speed at which a single ball Where Mc is the total mass of the charge in the mill and Tf is the torque LG A mill power equation for SAG mills volume of autogenous media and VS the volume of slurry This line intersects the data curve at abscissa value ยต as shown

The influence of mill speed and pulp density on the

torque on the driving shaft with the shaft speed rad/sec and hence excludes mill discharge density before dilution obtained during the sampling The ball

Motors and drives perform critical service throughout any mining
