IMPACT hammer crusher : THE FIELDS OF APPLICATION

Impact hammer crushers are hammer mills which are especially used for main and secondary crushing of feed materials from mining and pit and quarry industries.

THE FEED MATERIALS

Various kinds of ore, medium-hard rock just like raw gypsum, limestone , shale, petrol coke and similar feeding supplies.

THE MODE OF OPERATION

Impact Hammer Crusher

After entering the crushing radius with the rotor, the feeding material is grasped by the beater heads and crushed by becoming thrown against the beater head respectively the impact wall. A second crushing procedure is carried out within the lower section among the rotor as well as the impact wall. The impact hammer crusher is resistant to foreign matters entering the mechanism, thanks towards the flexible suspension in the beater arms on the rotor.

The setting with the impact wall towards the crushing radius with the rotor (gap width), in addition to the circumferential speed in the rotor, are the important determinants with the reduction ratio plus the final grain size distribution. The adjustment with the impact walls also functions as a compensation for wear and tear.

THE Unique CHARACTERISTICS OF IMPACT HAMMER CRUSHER

The rotor is a one-piece forged steel construction. Alternatively, it could be in particular constructed as a disc rotor. To guarantee a vibration-free operation, the drilling-holes to assistance the beater arm bolts are drilled on a special apparatus with an exactly equal division.

Impact hammer crushers are constructed in such a way that they can be operated at each rotor speeds, constant and variable. Ease of upkeep is guaranteed by inspection flaps along with a hinging device to open the housing.

The reversibility from the rotor and also the arrangement of impact walls on each sides guarantee an optimum use with the hammer heads without getting to become turned. As the hammer heads are wearing parts, they are able to lastly be replaced.

THE CONSTRUCTION OF IMPACT HAMMER CRUSHER

A reversed rotational direction is possible using the reversible impact hammer crusher. So both sides with the hammer heads are utilized. Using the standard impact hammer crusher model, the impact walls are mechanically adjusted.

Upon request, the impact hammer crusher may also be provided with hydraulic impact wall adjustment. Based on the crushing demands of many materials, the machines is usually driven in unique ways:

A – constant rotational speed Here, a belt drive is utilized. When the driving power is high, the driving disc is positioned separately. A

flexible or perhaps a liquid coupling is inserted towards the motor. If preferred, a reduction gear could be flexibly coupled as a direct drive instead of the belt drive.

B – variable rotational speed A variable rotational speed enables the operator to influence the final grain size distribution speedily and effortlessly. You'll find two models: The use of a manual transmission The use of a liquid control coupling with infinitelyvariable range of manage as well as a constant rotational speed in the course of load variation.

THE VERSATILITY

Depending on their application, numerous various machine models and additional equipment are used:

– Reversible impact hammer crushers

Here, the operating direction is reversed so that the beater heads are optimally utilized with out getting to be turned. Several unique drive concepts are obtainable. Impact hammer crushers can be operated with constant or variable rotational speed.

– Mechanically adjustable impact walls

To compensate wear and tear and to vary the grain spectrum.

– Hydraulically adjustable impact walls

For frequent adjustments within the form of function to become performed, based on product top quality and grain spectrum.

– Having a replaceable grate

To limit the quantity of oversized grain. Not appropriate for moist, sticky and clayey supplies.

– Housing with hydraulic opening mechanism

To open the housing. The needed time for replacing worn-out parts or perhaps a fully-equipped rotor, is thus considerably decreased.
