OPTIMUM PERFORMANCE ADJUSTMENTS
This section will explain how to adjust components for optimum performance.
9.1
MEDIA FLOW
The Media Regulator is threaded onto a 1 1/4” pipe nipple under the Storage Hopper. The
media hose is inserted into the 1 1/8” horizontal bore of the regulator. The thumbscrew is
provided to apply slight pressure against the media hose to prevent movement. The media
hose will partly cover the secondary air port. A smaller opening will increase media flow and
a larger opening will decrease media flow.

9.3
NOZZLE DIRECTION AND DISTANCE
Supporting each Suction Blast Gun are extension arms and knuckle assemblies. The
assembly permits the nozzles to be directed in any direction. The Suction Blast Gun should
be supported when loosening, aiming, and tightening the assemblies. A distance of six (6)
inches is recommended between nozzle and part. See Figure 5.
9.4
BLAST INTENSITY
The blast intensity on a part may be increased by one or more operating parameters: number
of nozzles blasting; raising Blast Pressure; reducing media flow; increasing blast time;
moving nozzles closer to part; and slower oscillation. To lower intensity, the reverse may be
used. It is recommended that only one parameter be changed at a time.
9.5
MANDREL SPEED
Mandrel speed is controlled by an adjustable potentiometer on the Operator Electric Control
Panel. A scale is provided to reference settings. Slower speed increases blast intensity and
faster speed reduces intensity.
9.6
BLAST PRESSURE
Blast Pressure is the most common adjustment for intensity. The Pressure Regulator may be
turned clockwise to increase and counter clockwise to decrease Blast Pressure.
9.7
RECLAIMER (SEE FIGURE 4)
The Reclaimer is supplied with a tunable secondary air adjustment. When the band is
properly adjusted, reusable media will be returned to the Storage Hopper while unwanted dust
and broken down media (fines) are removed from the system and conveyed to the Dust
Collector. Adjust the band as described below:
9.7.1 The band is joined at both ends by a bolt that must be loosened before adjusting the
secondary air. A slot pattern in the Reclaimer body has one (1) slot omitted. The
joined ends of the band must be located over the area of the omitted slot. Also no
Reclaimer slots should be visible through the band slots.
