Graduation in the spa park Hamm
In the western part of the Hammer Kurpark is the Gradingwerk Bad Hamm. Previously used for salt production, the plants sometimes called saline wall today serve pneumological therapy purposes, the microclimate of these plants is considered a particularly beneficial treatment for respiratory diseases.
In the case of facilities built for health purposes only, such as here in Hamm, the salt does not come from the ground. From a tank, a salt broth (brine) containing at least 14g dissolved salts per liter of water is passed through a pipe system and then trickled over a wall of blackthorn rice.
While the brine trickles down over thousands of fine branches of blackthorn bundles, the surface of the water multiplies. As a result, water is atomized and evaporated in the ambient air, which cools and absorbs salt particles and moisture. This moist, saline air has a positive effect on the respiratory tract and is very well suited for the treatment of respiratory diseases. Even for healthy people, the microclimate created in the plant is very beneficial and should help to prevent respiratory diseases. Furthermore, the fine salt crystals have a secretory action that cleanses the airways intensively from bacteria and allows the mucous membranes to swell, the moist salt air is thus attributed a good support of the self-cleaning forces of the respiratory tract.
The facility in the spa park was inaugurated in 2009 and donated on the occasion of the 150th anniversary in half by the Hammer Stadtwerke. The construction costs amounted to about 500,000 euros, of which the second half was the city of Hamm.
The graduation mill has a total length of 41.18 meters and a height of 9.5 meters. Between the nave and a head house there is a passage, on the east side a covered walkway with benches. There are more benches around the facility.
