How it works ?
The system of KU-15R machine is shown here in diagrammatic cross-section;
the arrows marked in red indicated abrasive flow from Abrasive Tank which
is a pressure vessel, to Blast Gun and its return via vacuum hose to Reclaimer.
The arrows marked in red & green represent recovery of debris, and dust
from Blast Gun. Abrasive is pressure fed from Abrasive Tank (A) to Blast
Gun (B) Blast Gun remains in close touch with surface to be cleaned. After
cleaning the surface, abrasive, debris and dust is vacuum conveyed to
Reclaimer (C) where good reusable abrasive is air-washed, sieved and then
returned to Abrasive Tank (D) for reuse. Thus only clean air is discharged
into atmosphere from (E) Dust Collector, Reverse air flow (vacuum) is
created by Compressed Air Ejector or by Vacuum Pump (F). Blast and automatically
transfers all dust, debris and used abrasive to Reclaimer via a vacuum
hose, four castors facilitate movement along work surface. A nylon brush
surrounds the gun body to prevent escape of abrasive and dust.
