Detailed study of 125/60 TPH Aggregate crushing Sand Plant using plethora of machinery

This paper elucidates the control mechanism employed for the speed control of three phase induction motors used in a sand manufacturing unit. Moreover, this plant uses three phase induction motors for its various operations and has a production rate of around 125-160 tons of sand per hour. These motors use variable frequency drives (VFD) which are based on programmable logic controllers (PLC). The paper expounds the operation of the plant in-depth, the drawbacks of using aforementioned method of speed control and the need for choosing other speed control strategies so as to improve the speed control of induction motors and thus increases the output of the plant.
