METHOD FOR VOLTAGE REGULATION OF A CRUSHING MOTOR TO OPTIMIZE THE CRUSHING POWER OF A CRUSHING SCREW AND THE DURABILITY OF THE CRUSHING MOTOR

摘要

PURPOSE: A method for voltage regulation of a crushing motor is provided to properly control the CT(Current Transform) voltage of a crushing motor according to different adhesion degrees of materials during drying and crushing processes. CONSTITUTION: A method for voltage regulation of a crushing motor comprises the steps of: setting the initial CT voltage as a first voltage(S100), operating a crushing motor for a predetermined time in response to the control of a controller(S120), determining whether the number of jamming of the crushing motor is equal to or greater than N(S130), determining whether the duration of N-time jamming is equal to or less than an hour(S140), increasing the CT voltage to a second voltage in case of N-time jamming of an hour or less(S150), and increasing the CT voltage to a third voltage in case of N-time jamming over an hour(S155).
