I.Instruction of Impact crusher:

Impact crusher is a new type of high efficiency crushing equipment, features are: small volume, simple structure, big crushing ratio, less energy consumption, large production capacity, uniform end product size, and selective crushing effect, is a very promising device; Impact crusher plate hammer and counterattack plate is the chief drawback of particularly easy to wear and tear, especially broken hard ore and abrasion is more serious, often need to change. At present due to the emergence of some wear-resisting material, has been applied in some metal concentrator.

II.Mainly application :

Reaction type crushing function processing under 100-500 - mm length material, resistant to pressure up to 350 million mpa, big crushing ratio, material after broken cube grains, etc. Widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, used to finely materials in chemical industry, etc. The row partical size can adjust, broken specification diversification.

III.Working principle:

Impact crusher is a kind of impacting energy to crushing material crushing machinery. Machine work, under the drive of the motor, the rotor high-speed rotation, the material into the plate hammer function area, and the rotor plate hammer impact broken, and then again to counter device is broken, and then back to the board from the back plate hammer function area is broken again, this process is repeated, material from big to small back into one, two, three cavity repeated broken, until the material being broken to the required size, is being exhausted from port discharge. Adjust the clearance between the back frame and rotor can achieve the purpose of the material discharging granularity and material to change shape. Stone directly by the upper machine in high speed rotating wheel; In high speed under the action of centrifugal force, and the other part to bypass around the rotary table by way of umbrella slungshot produced high-speed collision with high density of crushing, stone after fighting each other, and between wheel and the casing in the formation of vortex motion caused by repeatedly hit each other, friction, crushing, from the bottom to discharge. Forming closed-circuit circulation many times, controlled by the screening.

IV.Advantages:

1.The back plate and plate hammer gap can convenient adjustment, effective control of discharging granularity, grain shape good;

2.Ore crushing along the joint surface, therefore, less power consumption, high efficiency;

3.keyless connection, maintenance is convenient, economic and reliable;

4.Crushing function, high productivity, all parts, low abrasion, high comprehensive benefit;

5.High chromium plate hammer, impact resistance, abrasion resistance, impact large;

6.Simple structure, small volume, light weight, large capacity, low production cost. Inlet, high crushing cavity, to adapt to the high hardness material;

7.Broken than large, can reach 40, can simplify the crushing process, therefore, can make the three sections of the broken into two segments or a broken, lower mill equipment costs;

8.Selective crushing effect, and the broken product granularity evener, mostly cube shape stones. For bridge construction, construction of the high-speed road, port, airport has a wide range of applications.

V.Features :

1.Rotor back to withstand high moment of inertia and rotor hammer impact crushing force;

2.The optimization design into a low speed, much impact crushing cavity type crusher, its linear velocity is generally counterattack broken by 20% - 25%, low energy consumption to obtain high production capacity;

3.Has the function of tertiary crushing and shaping and broken than big, product shape is a cube, can the advantages of selective crushing;

4.The reasonable structure of plate hammer, has the advantages of loading and unloading fast and transposition, can shorten the time of the switch board hammer;

5.A new manufacturing technology, successfully developed a kind of high wear resistance and high toughness of chromium, molybdenum and vanadium alloy material, solves the problem hard material crushing. Greatly improving the service life of the plate hammer;

6.Unique back tooth plate, keyless connection, maintenance is convenient, economic and reliable;

7.Back is equipped with multi-function hydraulic station, a hydraulic high-speed discharge gap and stable counterattack plate vibration and body automatically open, etc.

VI.Performances :

1. New wear-resisting material plate hammer and counterattack plate and longer service life of lining;

2. Low inlet, facilitate production line arrangement and increase feed size;

3. The feeding port, high crushing cavity, to adapt to the material hardness, large blocks, less product powder;

4. High chromium plate hammer, unique counterattack plate, especially suitable for hard rock crushing, high efficiency and energy saving;

5. Hard rock crushing, high efficiency and energy saving; All the whole board structure make discharge more small size and cubic shape, no inner lines;

6. Hard rock crushing, high efficiency and energy saving;

7. The product shape is a cube, row partical size is adjustable; 8.Simplified crushing process;

8. Full hydraulic open, easy to maintenance and replacement of wearing parts;

9. Multi-cavity uniform broken, is suitable for crushing hard rock.
