pressure), and dust-collector filter loading (differential
pressure across the dust filters).
As a rule, larger orifice air jets and nozzles deliver more
media, requiring higher performance from the reclaimer.
When using larger nozzles, the maximum mesh size of
media will be smaller than normally recommended.
Using media finer than those recommended may
decrease visibility and, at some point, carryover to the
dust collector. Media coarser than those recommended
may be too dense for the reclaimer to recover from the
cabinet hopper.
1.11.2 Steel shot and steel grit:
Steel shot S-110 to
S-70 and steel grit 80-mesh to 120-mesh may be used in
a Pulsar Plus Cabinet with a 600 cfm power module
configured for using steel media and with a 1/4" or
smaller nozzle.
Using steel media requires a smaller diameter conveying
hose (usually reduced one size from standard), as
shown in Figure 3. Rubber curtains should be used to
protect the cabinet walls from peening, warping, and
rapid wear. For these applications, cabinets can be
ordered with reduced-size flex hose appropriately sized
for steel grit, and with rubber curtains installed. They
may also be field installed later. NOTE: Steel grit or shot
is too heavy to use with cabinets equipped with 300 cfm
reclaimers.
1.11.3 Sand and slag:
Sand and slag media are not
suitable for cabinet use. Sand should NEVER be used
for abrasive blasting because of the respiratory hazards
associated with media containing free silica. Slags are
not recommended for cabinet use because they rapidly
break down and are not recyclable.
1.11.4 Silicon carbide, aluminum oxide, and garnet:
These are the most aggressive of the commonly used
media.
Aggressive media may be used, but the service life
of any components exposed to the media will be reduced.
To avoid unscheduled downtime and maximize cabinet
life, periodically inspect the reclaimer wear plate, blast
hose, and nozzle for wear and replace parts as needed.
When using aggressive media only occasionally, install
an optional aluminum oxide kit, which includes rubber
curtains for the cabinet interior and a boron carbide-lined
nozzle. When using aggressive media on a regular
basis, install the aluminum oxide kit and a fully-rubber-
lined reclaimer. (Only available for Pulsar Cabinets with
600 cfm power modules). Rubber-lined reclaimers are
available on a 600-cfm reclaimer, as factory-installed
items, or field-installed liners can be installed later if it
has a removable top and is designed to accept liners.
Nozzles lined with boron carbide extend nozzle wear life.
Refer to Section 10.8
BNP Gun and Feed Assembly.
1.11.5 Glass bead:
Most beads are treated to ensure
free-flow operation, even in environments of moderately
high humidity. Glass beads subjected to excessive
moisture may be reused only after thoroughly drying and
breaking up any clumps.
1.11.6 Lightweight and fine-mesh media:
When
using lightweight (such as agricultural) media or fine mesh
(180-mesh and finer) media, the reclaimer inlet baffle
may need to be removed to retain media and avoid
carryover. On 600 cfm reclaimer models with a bolt-on
removable top, baffle removal and replacement is easily
accomplished, as explained in Section 7.13. Reclaimers
with welded-on tops require grinding to remove the
baffle, and once it is removed it cannot be replaced.
This guideline to media type and selection is based on standard 5/32" orifice air jet with 5/16" nozzle and average
conditions, such as air pressure, media-air mixture, visibility, contamination of parts being cleaned, humidity,
media friability, reclaimer cleaning rate, etc. As a rule, larger nozzles deliver more media, requiring higher
performance from the reclaimer. Larger air jets and nozzles decrease the maximum mesh size of media from
those recommended. Media that is finer than those recommended may decrease visibility and increase carryover
to the dust collector. Media coarser than those recommended may be too dense for the reclaimer to recover from
the cabinet hopper.
