Described main frame comprises casing, main shaft, rotor element and rectangular teeth liner plate; Rotor element is pulverized cutterhead by fan impeller, following draught fan impeller, first, second, third, fourth and is formed; Rotor element by flat key, be bolted on the main shaft, rotor element is vertically placed, bearing fixing is mixed on top chock in top; The bottom is joined lower bearing and is fixed on the step; Upper and lower bearing block is connected with casing with bolt, and the rectangular teeth liner plate, and is pulverized between cutterhead and kept less clearance in interior with bolt;

Also be provided with reflux on the main frame, the charging aperture of reflux communicates with fan impeller below, and the discharging opening of feeding back device communicates with inlet plenum.

Inlet plenum one end communicates with scroll feeder, and an end leads to main frame and communicates with following draught fan impeller top, and communicates with the discharging opening of reflux.

Cooling water coil is installed in the support, the machine oil that the cooling that is used for circulating is lubricated bearing.

The beneficial effect of the utility model is:

1, can be through the blade on the adjusting cutterhead and the fineness of the gap adjustment product between the rectangular teeth interior lining panel;

2, can be through regulating the rotating speed control product fineness of rotor;

3, this eedle is pulverized the efficient height to cellulose, and specific energy consumption is little, has excellent effects of energy saving and emission reduction;

4, temperature rise is low, does not influence cellulosic chemical property, can pulverize heat sensitive material;

5, possess drying effect, can effectively reduce material moisture, reduce humidity.

Description of drawings:
