  • SBM strikes back type crusher works academic

    The 41250mm X1250mm double rotor of my what configuration differs with having certain height below factory strikes back type crusher is a detailed ground to introduce double rotor to strike back the structure of type crusher, the characteristic of this kind of crusher is:
    (Two rotor have 1) certain height is poor (two turn at central line and horizontal the included angle between is 12. ) , enlarged the working angle of rotor. Make rotor has the possibility that enforces to expect, the 2nd rotor has the possibility that raises linear velocity, cause stock to achieve sufficient broken, win final product granuality demand thereby.
    (2) strikes back twice with the first class respectively to the rotor to motion board, the 2nd class strikes back board composition is thick break and finely and broken antrum. Rotor of the first class and strike back board stock from Xiaoyu 850 Ga are broken to LooM the left and right sides gives a person finely and broken speech; Rotor of the 2nd class strikes back with the 2nd class board continue to break stock be less than 20mm, via crusher lower platoon expects bar board is in eduction. This kind uses the concentration that distribute speech to turn over checkmate broken principle, degree of finish of OK and sufficient play is broken the action with the broken concentration of antrum.
    (3) two rotor contain a peen that number differs, peen height and peen figure are different and two rotor have different linear velocity, their circumstance cardinal principle is such: 4 peen are secured on the first rotor in all 8 bar, about the linear velocity with 38 small S is broken enter the chunk stock inside crusher, 6 fixed peen on the 2nd rotor in all 12 bar about the linear velocity with 50m/s, the stock that continues to will give the person's 100mm the left and right sides is broken the product granuality that asks into place.
    (4) to assure the quality of broken product (granuality) , the platoon makings punish in two rotor did not add platoon makings bar board.
    (5) rotor, bar and strike back board it is to form strike back the main body of type crusher.

    Strike back type crusher (say to pound type crusher again) belong to use the machine device that pounds can broken stock. the form that uses mechanical energy, use wallop “ from inside the crusher of ” broken principle, the crusher that wants brokener than the extruding with quiet pressure principle is advantageous. Afore-mentioned of all kinds breaking equipment (get type, roller type to wait) basically be the crusher that with extruding broken action principle gives priority to, and strike back type crusher is to use broken principle of wallop “ free ” to come of broken stock. Stock enters crusher in, basically be to be hit by high speed revolving board concussion, stock undertakes along bedding face, cleavage face alternative broken, be pounded the following stock achieves tremendous kinetic energy, and with very high rate, along blow board tangent direction is cast to the first class to strike back board, via striking back board pound action, stock is attacked again broken, strike back from the first class next board returned makings piece, what suffer blow board again is new bump, continue to give smash. Broken the stock after, cast to the 2nd class to strike back with very high rate again likewise board, attack again broken, bring about thereby striking back the broken action of the type of “ interlocking ” in type crusher. Be in when stock blow board and strike back board between in road going there and back, besides blow board and strike back outside pulled concussion action, still the photograph collide between stock attacks action. This kind of afore-mentioned processes undertake repeatedly, until broken the stock bead after.
    Strike back although type crusher appears later, but development is splitting, current, what the industrial department such as the cement that it already was in our country, housing materials, coal and chemical industry and mineral separation uses extensively at all sorts of stock is medium, finely in, also can use the thick broken equipment that makes stock. Strike back type crusher develops so quickly, because it has undermentioned important characteristic,basically be:
    (1) is broken than very big, of general crusher broken than the biggest do not exceed 10, and those who oppose checkmate broken machine is broken than be 30~40 commonly, can amount to most 150.
    (2) broken efficiency is tall, electric energy is used up low. Because of common stock fight impact strength to want than compressive strength small much, after because stock is mixed for many times by the high speed action of blow board,be being pounded at the same time, stock is attacked above all along the place with cleavage interface and flimsy organization crack, the broken efficiency of this kind of crusher is accordingly tall, and electric energy is used up low.

    (3) product granuality is even, smash too the phenomenon is little. This kind of crusher is to use kinetic energy (/ of square of E = Mv 2, the E in type is kinetic energy; M is the quality of makings piece; The athletic speed that V is makings piece) of broken stock, and the quality of stock of the kinetic energy bulk that every stock place provides a province and this piece becomes direct ratio. Accordingly, in broken process. Chunk stock gets of older rate broken, and the stock of lesser grain, fall in certain condition criterion not by broken. Reason is broken product granuality is even, smash too the phenomenon is little.
    (4) can choose brandish broken S is in in pounding broken process, stock above all along cleavage face broken, produce monomer depart E at stock with benefit
    (5) adaptability is big. of OK and broken brittleness, fiber mixes this kind of crusher in hard the following stock, special agree with of brittleness stock broken.
    (6) equipment bulk small, quality light, structure is simple, make easy, maintenance go to the lavatory.
