The job at Carborundum Universal, Kolkata was to re-do the whole plant with latest technologies and fully automatize it. We have provided several VFDs to the plant for all the AC motors involved in the whole plant, commissioned and programmed it. We have also provided PLC and HMI to automize and for ease of operation for the operators. The company makes sand paper.
Before the Operators had to operate 5 motors in one machine and synchronize all the motor to achieve the same speed in meters per minutes. And now they just have to give an input to say at what speed the whole machine should work. All the synchronizations of the motors are now done automatically. In one of the machine there are 7 motors now and all are synchronized automatically with the help of PLC.
