Hammer crushers are hammer mills that are particularly used for primary and secondary crushing of feed materials from mining and pit and quarry industries.
THE SPECIAL CHARACTERISTICS
The rotor is a one-piece forged steel construction. Alternatively, it can be especially constructed as a disc rotor. To guarantee a vibration-free operation,
the drilling-holes to support 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 both rotor speeds, constant and variable. Ease of maintenance is guaranteed by inspection flaps and a hinging device to open the housing.
The reversibility of the rotor and the arrangement of impact walls on both sides guarantee an optimum use of the hammer heads without having to be turned.
As the hammer heads are wearing parts, they can finally be replaced.
THE CONSTRUCTION
A reversed rotational direction is possible with the reversible impact hammer crusher. So both sides of the hammer heads are used. With the conventional
impact hammer crusher model, the impact walls are mechanically adjusted.
Upon request, the impact hammer crusher can also be provided with hydraulic impact wall adjustment.
Depending on the crushing demands of various materials, the machines can be driven in different ways:
A "" constant rotational speed
Here, a belt drive is used. When the driving power is high, the driving disc is positioned separately. A flexible or a liquid coupling is inserted towards the motor. If preferred, a reduction gear can 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 quickly and easily. There are two models:
The use of a manual transmission
The use of a liquid control coupling with infinitelyvariable range of control and
