Abstract
The utility model discloses an improved ring hammer of a ring-hammer type crusher, comprising a hammer body and a round through hole of the hammer body. The outlines of the end faces of the hammer body are regular polygons, and the center of the inscribed circle or the circumscribed circle of each regular polygon is concentric to the round through hole. Because the outlines of the end faces of the ring hammer of the ring-hammer type crusher are regular polygons, the contact area between the ring-hammer hammering face and a material is enlarged, the service life of the ring hammer is prolonged and the crushing effect is enhanced.
Description
Technical field
The utility model relates to a kind of ring hammer that is used for ring hammer crusher.
Background technology
Ring hammer crusher is a kind of impact rotor formula disintegrating machine that has the ring hammer, after material enters disintegrating machine, at first be subjected to fragmentation with the ring hammering blow effect of rotor high-speed rotation, pulverized material obtains kinetic energy from the ring hammer simultaneously, rushes at crushing shell at a high speed, is subjected to broken for the second time, fall on the sieve plate then, be subjected to encircling shearing, extruding, the grinding of hammer, and the mutual collision between material and the material is further broken, and sees through the sieve aperture discharge.The ring hammer mostly is circular at present, is called top fuller again.Its outer ring surface is the line contact as the scope of attack when its bump material, because contact area is little, crushing effect is bad, the wearing and tearing easily of ring hammer.
Summary of the invention
The utility model provides a kind of improved ring hammer crusher ring hammer at the deficiency that prior art exists, and changes circular outer ring surface into regular polygon, is the face contact when its bump material.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of improved ring hammer crusher ring hammer, comprise hammer body and circle open-work thereof, the end profile of described hammer body is a regular polygon, and the inscribed circle of described regular polygon or the circumscribed circle center of circle are concentric with the circle open-work.
Further, the limit number of described regular polygon is at least six.
The beneficial effects of the utility model are, because the ring hammer tip facial contour of ring hammer crusher is a regular polygon, have increased the contact area of the ring hammer scope of attack and material, can prolong the service life of ring hammer, strengthen crushing effect.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Accompanying drawing is the utility model structural representation.
The specific embodiment
As shown in the figure, a kind of improved ring hammer crusher ring hammer, comprise hammer body 1 and circle open-work 2 thereof, in order to increase the contact area of the ring hammer scope of attack and material, the end profile of hammer body is designed to regular polygon, the inscribed circle of described regular polygon or the circumscribed circle center of circle are concentric with the circle open-work, and the limit number of described regular polygon is at least six.Described round open-work 2 be used for ring hammer crusher hammer dish on bearing pin hinged.The utility model can be cast and form, and also can forge to form.
Claims (2)
1. an improved ring hammer crusher ring hammer comprises hammer body and circle open-work thereof, and it is characterized in that: the end profile of described hammer body is a regular polygon, and the inscribed circle of described regular polygon or the circumscribed circle center of circle are concentric with the circle open-work.
2. a kind of improved ring hammer crusher ring hammer according to claim 1, it is characterized in that: the limit number of described regular polygon is at least six.
