It begins with a brief history of the mixer grinder, originating from Herbert Johnson's invention in 1908. It then discusses key parts of the mixer grinder like the motor, blades, and jars. The working principle is that the motor converts electricity to mechanical energy using a coil and magnetic field to rotate the blades at high speed.
