For some applications the nature or quantity of the work to be blasted means that a full recovery system is unsuitable or too expensive.
For these applications Protoblast can supply a number of relatively inexpensive partial recovery systems which still allow you to avoid the disadvantages and risks of blasting in the open.
The recovery area of a partial recovery system is covered with grating or perforated plat panels. These allow abrasive to fall into a hopper feeding a narrow oscillating tray. The remaining floor area of the blast chamber is covered with steel plate, making it easy to sweep abrasive into the hopper.
