Description :

In an fabricated enclosure adjustable 2-3 breaker plates (sometimes spring loaded) are suspended. A massive rotor, with high rotational inertia, has been fitted with 2 to 6 blow bars, rotates with velocity of 25M/sec. to 35/M/sec. Material is fed at an angle & at a position, on to rotor in such a way that Blow-bars, almost without losing their R.RM., hit the material with such an impact that material shatters in the space before hitting the breaker-walli. Further crushing takes place, after the material hits against the breaker-plate. Rebounded Material is again impacted back on to breaker plate for further crushing. As the material breaks due to Impact & due to input of more kinetic energy, material breaks equally in all directions giving cubical product.

Product grain distribution / analysis depends mainly on rotor speed and can be further adjusted by breaker plate setting. In order to prevent possible damages caused by foreign bodies (like metals), breaker plates are spring loaded.

Construction :

Impactor consists of following main parts :

1. Rotor Assembly with blow Bars, Bearings & flywheel.
2. Lower Body.
3. Upper body with feeding chute.
4. Upper body rear side

Rotor Assembly :

Is mounted inside the steel fabricated Housing is mounted on heavy duty over dimensions self aligning roller bearings, mounted in steel pedestals, with labyrinth seals. Flywheel is keyed to shaft, or fixed to shaft through shear-pin arrangement.

Blow Bars :

Massive blow bars made of wear resistant steel & having very high toughness, are fixed to body of the rotor by means of special forged high tensile bolt, so that they can be easily adjusted and if required can be replaced, in very short time.

Rotor Body :

is a very heavy fabricated body, welded with high tensile electrodes and stress relieved, Rotor body is very accurately machined & mounted on main shaft of the Impactor.

Rotor Shaft :

is made of high tensile, heat treated alloy steel forging, duly stress relieved and accurately machined & ultrasonically tested for hair line cracks.

Breaker Plates :

Made of wear resistant steel and are mounted on fabricated stock. Duly machined & stress relieved. Breaker plates are fixed to break plate stocks by special forged high tensile bolts.
