Do You Have A Good Knowledge Of Impact Crusher?

Material inlet 7 down to the broken body in 6. In order to prevent broken blocks of material from inlet fly out, at the inlet is equipped with a row of chain 8. Into the blocks of material fell on grid screen 9. Small pieces via sieve straight exhaust port 12, bulk materials ring true count fell on rotor of 1. Rotor is equipped with a raised flat hammer of a certain height above 2. Plate hammer, according to the size of a rotor diameter of 4~6 row. From motor after coupling and shaft-driven rotor rotation of the rotor. Board blocks in high-speed rotating back and forth between hammer and counterattack the 3 collision breaks, 1 grid screen, rotors, the first 3 of counterattack plate and feed chains composed of sharp shock-processing zones within the space of 10, items broken and it falls to counterattack the 3 and 4 of counterattack plate and rotor within a second impact zone made up of 11 l further impact crushing. Rotor broken material below the nesting population discharge 12.

Back end of the Board articulated 13 live, hung in the chassis, suspension bolts 5 position it on the other end. When there are large or hard to break items attached to the counterattack and between the rotors, counterattack plate subject to greater pressure on the backward moving away so a clamp material may pass to avoid the rotor damage. Materials after the counterattack by the repeated. Increasing the number of crushing cavity (that is, increasing the number of counterattack plate to increase the interval) can enhance the selectivity crushing, increase material reduction ratio.

Thus increasing the crushing Chamber after the lower rotor rotating speed can be taken, too large in size can be reduced, lower flat hammer wear. Three counterattack three crushing cavity structure, low power consumption, high production capacity, 400 rn/Tt large materials can be broken to the 0~35 rnlTl. Production capacity 30~240 t,/h. Double rotor impact crusher body, arranged in two parallel installed rotors, rotor and a certain degree of height difference of two. First level higher rotor position, center line and second-stage rotor both rotors horizontal angle of about 12 degrees online. First level for heavy rotors, used for coarse; second level rotor speed faster and can meet the requirements of the final product. Primary and secondary rotor is bolted solid containing 12 plate hammer distribution into 6 rows. Flat hammer high manganese steel casting. Solid-mounted on the spindle of the rotor, bearing supported at both ends in the body, each of the two rotors are connected by two motor hydraulic coupling, V-belt transmission, with high speed rotation.

Hydraulic coupling can reduce starting loads, reduced motor capacity can play a protective role. First counterattack and second counterattack had cavities counterattack plate is hinged at one end and the other is adjusting bolt. Flat hammer gap increased or because of resulting parts wear, such as product size to be adjusted at the request of gap, is adjust adjusting bolt to adjust the clearance of counterattack plate and plate hammer. In order to take full advantage of the kinetic energy of the material discharged, elimination of individual discharge of bulk materials to ensure quality of product size indicator, in the second primary rotor discharge port are integer and fixed grate plate counterattack. All of grate plate and counterattack with high manganese steel manufacturing.
