Background technology
At present, China still has many cement production enterprises using ball mill grinding raw material, because the energy consumption of ball mill grinding raw material is high, therefore reduces into abrasive particle degree, and " many broken few mills " is energy-saving and cost-reducing effective way.But in conventional, fine crushing hammer crusher (seeing China professional standard JB/T3766-2000), because structure falls behind, in order to obtain thinner product, need to be equipped with discharge grate closed disintegrating chamber, and in discharge grate workspace, there is rolling of poor efficiency in material between tup and double-edged fine-toothed comb, grind, both consumed energy excessively, causes again the scraping wearing and tearing of the working medias such as tup, has shortened their working life.Especially, for comparatively moist raw material, be also easy to occur to comb seam obstruction, produce the accident of interrupting.In addition because discharging is thick, therefore cause the energy consumption of follow-up ball mill grinding high, yield poorly.
From the above, in traditional dependence discharge grate control marker size, the fine crushing hammer crusher reversible that certainly will more reasonably cancel discharge grate by structure replaces without double-edged fine-toothed comb hammer mill, but, cancel discharge grate and must ensure that raw mineral materials reaches required marker size Zi the upper end that enters crushed zone to the degree of crushing of crushed zone lower end, if this technical problem can not effectively solve, reversible cannot embody without the advantage of double-edged fine-toothed comb hammer mill so.
Can be seen in the technical information without double-edged fine-toothed comb hammer mill about reversible in disclosed Chinese patent literature, " reversible hammer crusher of large reduction ratio " that for example Granted publication CN2832295Y recommends, it is by regulating the gap length between movable destroyer and tup (tup is located on the hammer dish being fixed on main shaft) to implement to control to broken ore grain size, " without the grid section reversable heavy hammer chrusher " that and for example CN2829882Y provides, this patent scheme has the effect playing the same tune on different musical instruments with aforesaid CN2832295Y, by regulating gap length between counterpunch board lower end and the tup of rotor to control the big or small object of building stones crushed particles, even and if the large building stones of water content also can brokenly process (the Instructions Page 3 12-13 that sees this patent is capable) to it, for another example CN200981006Y disclosed " bidirectional reversible impact breaker " although this patent scheme for broken coal, but its concrete structure is also similar with aforementioned CN2832295Y, by regulating the gap between tup and crushing shell to control discharging-material size (seeing Instructions Page 2 the 12nd row), and then as typically having " reversible hammer crusher of large reduction ratio " as CN202078925Y discloses, this patent scheme is except can be to the gap adjustment between counterpunch board and tup, also rotor structure is done to improvement, except one-level governor motion and two-stage governor motion for counterpunch board is regulated, on central shaft, interval arranges a hammer dish (patent counterweight sheet), and by hammer axle, tup is set on each hammer dish, therefore for first three items patent scheme, crushing effect is promoted, be that the ratio of reduction is large, make broken material without carrying out two-stage fragmentation by two-stage disintegrating apparatus again.But, be discoid and tup and distribute sparse owing to being arranged at one group of hammer dish on central shaft, particularly, after a corresponding tup between adjacent hammer dish, need to cross a hammer dish position and between two adjacent a pair of hammer dishes, configure a tup again, so cause the large and tup limited amount in space, thereby crushing efficiency is exerted an influence, and especially, the granularity of the material after fragmentation is because of compared with can not being directly put to flour mill grinding greatly.In addition, shown in the Figure of description of this CN202078925Y, because the arrangement of epitrochanterian tup is similar to " jaw crusher (the Impact Hammer Crusher) " of German AUBEMA company, therefore exist bulk material to exceed the anxiety of the thickness of single tup, the strike effect that produces thin dense uneven so be subject to the interference of adjacent tup, not only reduce crushing effect, and increased the wearing and tearing of tup end face.
