APPARATUS FOR PULVERIZING RAW COAL CAPABLE OF MEASURING THE PARTICLE SIZES OF THE RAW COAL SUPPLIED INTO A PULVERIZER IN REAL TIME

摘要

PURPOSE: An apparatus for pulverizing raw coal is provided to control the revolutions per minute of a motor driving a pulverizer based on the measured particle sizes of the raw coal.;CONSTITUTION: An apparatus for pulverizing raw coal includes a conveyor belt(10), a pulverizer(20), a particle size measuring unit(30), and a controlling unit(40). The conveyor belt transfers raw coal from a linear storage. The pulverizer receives the raw coal from the conveyor belt. The particle size measuring unit is installed at the upper side of the conveyor belt. The controlling unit controls the pulverizing intensity of the pulverizer based on the particle size of the raw coal. A plurality of pulverizing tools(22) is installed at the outer circumference of a hub(21). The hub is driven by a motor.;COPYRIGHT KIPO 2012
