Described hammer leaf is rectangle laminated structure, and the central annular of described rectangle laminated structure is non-quenching district, Remaining area is outer shroud quenching district, and after the heat treatment of two ends, hardness reaches HRC 56-62.

Described main shaft uses ring-type lathe grinding to be that diameter is incremented by the stepped shaft formed successively.

Described sieve uses quality steel plate brake forming, and its arc is suitable with upper machine body radian, in steel plate Punching the most at equal intervals on face, forms sieve aperture.

The end of described main shaft is additionally provided with pulley assemblies, described pulley assemblies include belt wheel, bolt, sealing ring, Bearing, bearing (ball) cover, be pasted with sealing ring, and be bolted between bearing and bearing (ball) cover, bearing End sleeve is provided with belt wheel, and is bolted.

The two sides symmetry of described belt wheel is respectively equipped with an annular groove, and its central authorities are provided with the logical of a band convex groove Hole, its foreign steamer edge is from top to bottom sequentially provided with some projections, is groove between adjacent two projections.

It is additionally provided with screw-down type grease cup on described rack sleeve.

This utility model provides a kind of compact conformation, simple in construction, easy to operate roughage mill, Setting former and later two rotors in this pulverizer, annular is provided with some hammer leaf groups, has some hammer leaves in each hammer leaf group, Production efficiency is high, it is possible to material carries out layering effectively and pulverizes, can produce repeatedly shear action simultaneously, Thus reach to improve yield, improve the uniformity, prevent the purpose of stifled sieve.
