A Liquid Resistance Starter (LRS) sometimes referred to as an electrolytic starter or rotor starter supplies power necessary to drive large motors by employing an electrolytic resistance utilising moving electrodes in an electrolyte solution. Liquid Resistance Starters are designed for controlled starting and speed control of large motors
Liquid Resistance provide high starting resistance to rotor circuit, cutting the resistance sleeplessly synchronizing with Motor Acceleration to very low or negligible value near Full Load speed. This gives a high Starting Torque and very smooth start. The above figure shows the comparisons of Grid Resistance Start and Liquid Resistance Start.
31.07.2003· I've got a 500kW, 6.6kV slip ring induction motor, which uses a liquid starter to bring it up to speed and is then switched to synchronous operation. The starter has movable plates rather than relieing on heating to change the resistance. When starting the motor the operator monitors the stator current and manually controls the starter, keeping the stator current just below the motor protection
The secondary starter you are mentioning is commonly referred to as a vapormatic starter.It is based on the difference in resistivity between a liquid electrolyte and its vapour. The passage of the starting rotor current causes partial vaporisation of the electrolyte and thereby adjusting the resistance and starting torque to optimum values. During the acceleration of the motor to rated speed, the thermal
Cryogenic grinding is a process where thermally sensitive and elastic substances are successfully processed by cooling with liquid nitrogen. The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile

Planetary ball mills. A planetary ball mill consists of at least one grinding jar, which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars according to a fixed ratio. The grinding balls in the grinding jars are subjected to superimposed rotational movements. The jars are moved around their own axis and, in the opposite
