Water pump—Using the soft stop function, the water hammer of the pump is relieved when it stops, saving the cost of system maintenance. Ball mill-use voltage ramp to start, reduce the wear of gear torque, reduce maintenance workload, save time and money. Fan-reduce belt wear and mechanical impact, saving maintenance costs.
Besides of the motor soft starting, VFD also can control the motor speed, to save energy. Cost: VFD's cost may be as high as triple as the 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 ...
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls,flint pebbles ...
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. In overhead crane controls, setting a soft start to begin traversal motions with a capacity load on the crane or trolley can result in a 'jack rabbit' starting jump when the crane is unloaded.

Ball milling is a type of grinder used to grind materials into fine powder. Ball mills rotate around a horizontal axis, partially filled with the coarse salt to be ground plus the grinding medium. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages.
Effect of Ball Size and Properties on Mill Grinding Capacity Current ball milling theory suggests that grinding capacity is influenced by the size of balls charged to the mill. In selecting the appropriate ball charge, the first objective is to determine that ball size which will grind the coarse particles most efficiently. This size should be the largest ball size charged to the mill. The ...

As I said in my earlier post that, starting toque requirement of ball mill application is high about 70-80%, so soft starters are not appropriate, as it is basically used for reducing excessive torque during starting. In ball mill the starter is required which gives sustained higher torque during it's operation.
