Abstract
The utility model discloses a double-shaft hammer type impact crusher which comprises a crusher body, and a feeding hole and a discharge opening formed in the crusher body, a hammer head is distributed on a spindle in the crusher body and is connected with a driving motor through the spindle; the crusher body is a vertical circular crusher body; the upper circular crusher body is communicated with the feeding hole to form a snail-shaped feeding hole and comprises an upper spindle and a lower spindle; an upper hammer head and a lower hammer head are distributed on the upper and lower spindles and are respectively arranged in an upper crushing chamber and a lower crushing chamber in the upper and lower circular crusher bodies; the upper spindle and the lower spindle are respectively connected with an upper driving motor and a lower driving motor which are independent of each other. Three-time material impact crushing is finished by adopting a secondary crushing mechanism, so the traditional sieve plate design is omitted. Therefore, the crusher has the advantages of relief blockage prevention and high crushing efficiency, the service life of the hammer head is prolonged by 50 percent, and the energy consumption is reduced by 20 percent. In addition, the traditional sieve plate design part is removed, and the requirement on materials with the moisture content of more than 10 percent is avoided. The crusher is suitable for crushing broken rock, coal gangue, cobble and residual slag in steel works.
Description
Technical field
The utility model relates to a kind of for mine material beater grinder, is a kind of twin shaft hammer impact breaker specifically.
Background technology
For pulverizing the disintegrating machine of mine material, be mostly single rotor hammer mill at present, circle by the tup in motor drive shaft, moisture content is not more than to 10% crushing material, particle after pulverizing, through the sieve plate control material type of material controlling, thereby completes primary fragmentation process.Conventionally the speed of mainshaft is subject to bearing limit velocity restriction (biserial radial bearing is generally not more than 1000 revs/min), causes breaking capacity not reach desirable effect.In addition, due to material controlling sieve plate being installed on single rotor hammer mill, and then after tup wearing and tearing, can cause the distance between tup and sieve plate to increase in process of production, easily cause the very large frictional force of generation between tup, material and sieve plate three, to such an extent as to machinery equipment produces very large power consumption waste.Simultaneously, also because of machinery equipment frictional force is excessive and material blocks up vexed car, overlong time motor overcurrent damages motor circuit.In addition, as the material that moisture content is greater than 10%, also can cause sieve plate gap to block phenomenon, equipment cannot normally be produced.
Summary of the invention
In view of above-mentioned present situation, the utility model provides a kind of twin shaft hammer impact breaker, makes material after tertiary crushing, directly discharge the granularity requiring, and material moisture is not had to particular requirement.Also there is tup service life of raising simultaneously, reduce energy resource consumption.
Technical solution of the present utility model is: a kind of twin shaft hammer impact breaker, comprise body, and the charging and discharging mouth which is provided with, and be positioned on the main shaft of body and be distributed with tup, be connected with drive motors by main shaft; Wherein said body is a upper and lower circular body, after being communicated with charging aperture, upper circular knitting machine body forms the charging aperture of a snail-shaped, there is upper and lower main shaft, on it, be distributed with in the upper and lower crushing chamber that upper and lower tup is arranged on respectively upper and lower circular body, described upper and lower main shaft connects respectively two independently upper and lower drive motors.Therefore, material hits for three times broken by the superior and the subordinate, the granularity ratio of material is improved greatly.Like this, will remove the installation of sieve plate, also just remove the requirement that moisture content is greater than to 10% material from, effectively also solve sieve plate gap and blocked phenomenon to the normal impact of producing of equipment.
During this is novel, the upper and lower circular body in related body is the structure of a split.
In above-mentioned, the combining structure body of described split comprises body seat and organism top case composition.
Further, related organism top case top be hinged for the hydraulic cylinder of opening.The unlatching of organism top case when convenient for maintaining.
The utility model, because having adopted two stage crusher structure, has not only improved the granularity of material fragmentation, but also has removed sieve plate parts, makes the wear problem of its obstruction that has solved the excessive formation viscous material of moisture content to tup.Therefore, reach 50% the service life of not only having improved tup, reaches 20% but also be conducive to reduce energy resource consumption.Be applicable to the fragmentation that fractured rock, gangue, cobble and steel mill left in slag.
Brief description of the drawings
Fig. 1 is this novel schematic diagram;
Fig. 2 is Figure 1A-A cutaway view.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
See a kind of twin shaft hammer impact breaker shown in Fig. 1, Fig. 2, comprise body 11, body 11 described in the present embodiment is upper and lower circular bodies, on circular body, be provided with charging aperture 5 and liner plate 6 described, and lower circular underpart is provided with material mouthfuls 13, wherein go up circular knitting machine body and is communicated with the charging aperture of a snail-shaped of formation afterwards with charging aperture 5.In the upper and lower crushing chamber forming at the upper and lower circular body of described body 11, correspondence is provided with main shaft 9 and lower main axis 3, upper rotor part dish 8 and the lower rotor part dish 10 of distribution are housed on main shaft 9 and lower main axis 3 on described, and be positioned on upper rotor part dish 8 and lower rotor part dish 10 upper ram 7 and the lower ram 2 installed, the upper main shaft 9 of the present embodiment and lower main axis 10 respectively by belt (in figure not mark) with two independently upper and lower drive motors 12 and 1 be connected, also comprise on main shaft 9 and lower main axis 10 stability that stabilizer 4 keeps transmission be housed respectively.During this is novel, the upper and lower circular body of related body 11 is Split type structure bodies.Split type structure body described in the present embodiment comprises that body seat 15 and organism top case 16 form, described organism top case 16 tops be hinged for the hydraulic cylinder 14 of opening.
Therefore, this novel employing reaction type smashing principle, make material enter upper crushing chamber by the charging aperture 5 of snail-shaped, complete first strike fragmentation by the High Rotation Speed of upper ram 7, make broken material mutually hit second strike fragmentation by the material in the process of upper crushing chamber and lower crushing chamber, make the material of second-time breakage enter lower crushing chamber, completed and hit for the third time fragmentation by the High Rotation Speed of lower ram 2 again, the material that is broken into granularity requirements finally by three strikes is discharged smoothly by discharging opening 13.
Implementing this novel key is to have adopted two-stage crushing mechanism to complete material to hit fragmentation three times, has removed traditional sieve plate design.Therefore, have discharge without obstruction, crushing efficiency is high, tup service life 50%, Energy Intensity Reduction 20%.
