ball mill soft starter frequency drive manufacturer Grasping strong production capability, advanced research strength and excellent service, Shanghai ball mill soft starter frequency drive supplier create the value and bring values to all of customers.
Torque delivered would be around 1.6 x Full load torque, very typical for a ball mill or sag mill as Chris mentioned. Correct measurement in the rotor current can be done with the likes of hall effect transducers or even shunts but not clamp-on ammeters unless they use hall affect or similar technology.
The difference between VFD and Soft Starter. If the motor works at full load all the time (means no need to vary the speed), then soft starter is your selection. In other case, say the ball mill works at 80% load, then choose the VFD, the saving energy will pay back to the VFD cost in future operation. View More
The difference with Soft Starter vs Variable Frequency Drive (VFD) is the method of starting employed. A soft starter reduces voltage, not Hertz, and as such the starting torque at 2-3 Hz is next to nothing. The soft starter is essentially robbing the motor of voltage at all points between 0 and 59 Hz, peak (Line) voltage met at 60 Hz.

Oct 05, 2015· The disadvantage of the soft starter technology compared to the frequency converter is that it is unable to control the speed and is unsuitable for applications requiring speed control. When starting loads with high inertial torque, for example in ball mills, it is easily applicable and has to be selected at a higher power level.
Implementing the AC variable frequency drive technology from Benshaw will provide reliable motor control, along with financial savings and improved asset protection. The reliability of Benshaw's drive technology leads to increased production and greater uptime by reducing maintenance downtime. - Download Ball Mill Positioning Brochure

Hard start of mill motor, throwing ball charge Most mills are designed with a soft starter arrangement; a typical mill starter system could include a Liquid Resistor Soft Starter (LRS) or Variable Frequency Drive (VFD), or it could be a clutch. Regardless of the system used, .
Variable frequency drive for Chinaware ball mill It is commonly said that it is hard to perform energy saving reconstruction to the Chinaware ball mill. However, this machine always contributes at least 80% of the factory's total power consumption.
CCVs are used for driving mine hoists, rolling mill main motors, ball mills for ore processing, cement kilns, ship propulsion systems, slip power recovery wound-rotor induction motors (i.e., Scherbius drives) and aircraft 400 Hz power generation. The variable-frequency output of a cycloconverter can be reduced essentially to zero.

The plant has totally reconstructed 37 Chinaware ball mills with 37 sets of Gozuk variable frequency drives. Take one of its 40T Chinaware ball mill as an example: the power of this machine's motor is 132KW, and actual working power is 115KW. This machine works 18 .
2) Base on the motor power, current and load characteristic to choose the soft starter. Generally, the soft starter capacity slightly larger than the motor operation current capacity, and increase a step power for some heavy loads, such as: crusher, ball mill, hoist, long belts, mixers, fans, etc.
