Blasting technology Xintech - Automatic screw cleaning system

Automatic screw cleaning system


Automated, absolutely abrasion-proof removal of plastic coating on screw & compounding elements. The constantly increasing quality standard requires innovative solutions. Screws with a ø of 14 - 180mm accross a length 1-5m can be cleaned (other lengths and diameters upon request). The entire blasting and transport unit is controlled by simply programming cleaning processes via touch panel. depending on the level of soiling, up to 5 cleaning zones can be staged separately. Manual cleaning is also an option.

Sophisticated sensor technology for automatic screw advancement and return.
depending on the soiling level the screw can be divided into 1 to 5 zones of effective length
and programmed separately, blasting time/feed
Economic, since non-contaminated zones can be skipped, saves time and blasting material.
Automatic feed calibration.
