Pulverizer

The utility model discloses a pulverizer, including the frame, powder motor, crushing case, the powder motor is installed in the frame be provided with the defeated motor of expecting in the frame, defeated material motor is connected screw feeder and is constructed with the material transport extremely smash the case, defeated material motor is connected with the PLC controller by the control of variable frequency speed governing(VFSG) ware before the variable frequency speed governing(VFSG) ware, be connected with electric current acquisition sensor on the powder motor, electric current acquisition sensor with the PLC controller is connected, is sent the rotational speed of the defeated material motor of digital signal control variable frequency speed governing(VFSG) ware control by the PLC controller. The utility model discloses energy -conserving automatically regulated carries the speed of material, and the electric current that makes the pulverizer motor is reasonable interval the floating of one, and the feed is stable, and the powder motor is the excess load not. Pulverizer neither can dally, also bad motor of will not card dead roasting. Output highest like this, the energy consumption is minimum.
