By bearing 16 and fixing seat 15, so that driven shaft 13 is limited in rotation in main body 1, thus make driven shaft 13 in rotation,
It will not shake, cement be poured into main body 1 by feed inlet 3, cement is fallen on impeller 14 and teeter column 19, passes through impeller
14 rotation, cement rotate in main body 1 under the drive of impeller 14, to make to collide and occur between cement and cement
Broken, when impeller 14 is in rotation, one interlaced state of formation, makes cement between impeller 14 and fixed teeter column 19
It is crushed again, when cement falls into the lower section of main body 1, the gap formed between teeth 20 and teeth 20, again by cement
It squeezes, to keep the degree of grinding of cement more careful, the cement after crushing then passes through filter plate 21, falls into discharge port 6, leads to
Spiral layers 7 are crossed, so that cement when falling, is that rotation is fallen, so that the speed of cement whereabouts is reduced, so that cement and storage
Impact force between device becomes smaller, when motor 10 work when encounter pound hit or hit when, protecting frame 22 will protect motor 10
Shield, so that reducing motor 10 probability damaged occurs, while by heat release hole 23, so that the heat that motor 10 generates dissipates outward
Hair, by observation panel 24 so that the working condition inside main body 1 is understood, the component inside main body 1 when something goes wrong,
Motor 10 is closed, belt 12 is removed from driven shaft 13, then bolt 5 is back-outed out of threaded hole 4, so that top cover 2 and master
Body 1 is no longer fixed, and top cover 2 is taken away from main body 1, so that driven shaft 13 and impeller 14 take out from main body 1, while by mounting plate
18 are taken out from main body 1 by card slot 17, consequently facilitating the maintenance of pulverizer, the content category that is not described in detail in this specification
The prior art well known to professional and technical personnel in the field.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
