Application:
The machines are designed to clean small and medium-size iron and steel castings of dimensions and weight within the limits indicated in the technical specifications below. The cleaning process is effected by shot ejected by a projecting rotor in a closed working chamber on a perforated rubber belt stretched on drums. Castings are removed from the machine by activating reverse gear of the belt. Castings are loaded into the machine by loading hoists type WOWT-120C and WOWT-400A which are ordered separately.
Advantages:
Owing to partially automatic working cycle the fettling operation is simple and safe. One worker is enough to operate the machine.
