KUM-SA Tunnel type sheet metal and profile shot blasting machines are produced for blast flat steel products and construction elements. It can be produced in intended sizes. The machine forms of main body, entry and exit rollers, filter unit, turbines, elevator, separator, dust catcher and control panel. Places where the türbine in the cabin touches directly are covered with 12-14 manganese moulding or sheet metal. Speed of the system can be regulated by speed control device. With the turbines that are placed under and upper parts of the system, all materials can be blasted at a time. It is used for surface cleaning of pieces like sheet metal, steel construction, IPE, HEA, NPU and NPI, profile, lama, corner iron. 

The material which will be blasted is placed on the conveyor safely. Intended speed of the materials which are present at entry and exit of the machine can be regulatable with speed control system. Speed will be regulated by speed control unit. The turbines that placed under and upper parts of the machine body, bombard from bottom and from above and in this way all parts of the material are cleaned at a time without being turned over. Elevator carries the steel balls fall into the machine, to the seperator with the buckets attached on the belt. Dusty steel balls which are brought by the elevator fall into the separator. Steel balls are separated from dust with strainer. Thus, dustless steel balls are transfered to the turbines. And dust pass through dust catcher and then they are caught in the filter. With filter, dust can’t go out. Cleaning of the filter is done by automatic pulses. Filter cartridges are made up of ultra web quality imported paper and has 99% dust holding capacity. Cleaned workpiece comes out from bombartment range is taken from on the conveyor safely and now it is ready for other procedures.
