BNP PRESSURE BLAST CONVERSION KIT Page 1
1.0 INTRODUCTION
1.1 Scope of Manual
1.1.1 These instructions cover set-up, operation,
maintenance, troubleshooting, optional accessories, and
replacement parts for BNP pressure blast machine/
reclaimer conversion kit. A supplemental manual is
provided for the Sentinel metering valve.
1.1.2 These instructions also contain important
information required for safe operation of the equipment.
Before using this equipment, all personnel associated
with the blast cabinet operation must read this entire
manual, and all accessory manuals to become familiar
with the operation, parts and terminology.
1.1.3 The following instructions refer to cabinet
functions for operational purposes only. The cabinet
used with the conversion must have the air changes,
velocities, dust collection, and other capacities to enable
its use with this pressure system.
1.2 Safety Alerts
1.2.1 Clemco uses safety alert signal words, based on
ANSI Z535.4-1998, to alert the user of a potentially
hazardous situation that may be encountered while
operating this equipment. ANSI's definitions of the signal
words are as follows:
This is the safety alert symbol. It is used to
alert the user of this equipment of potential
personal injury hazards.
Obey all safety messages that follow this symbol to
avoid possible injury or death.
CAUTION
Caution used without the safety alert symbol
indicates a potentially hazardous situation
which, if not avoided, may result in property
damage.
Caution indicates a potentially hazardous
situation which, if not avoided, may result in
minor or moderate injury.
Warning indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
Danger indicates an imminently hazardous
situation which, if not avoided, will result in
death or serious injury.
1.3 General Description
1.3.1 BNP pressure conversion kits consist of two
major components:
1. Blast Machine Assembly
2. Reclaimer Assembly
See Figure 1 for a push thru arrangement with a dry
filter. Figure 2 shows a pull-thru arrangement with a
reverse-pulse dust collector.
1.4 Theory of Operation
1.4.1 When the air supply is on, and the cabinet and
exhauster are correctly set up for operation, the blast
machine is ready for operation. Fully depressing the foot
pedal pressurizes the blast machine, and propels the
media through the blast hose and out the nozzle. After
striking the object being cleaned, the media, along with
fines, dust, and by-products generated by the process,
fall through the mesh work table into the cabinet hopper.
These particles are drawn into the reclaimer for
separation. Dust and fines are first separated from the
reusable media. Next, the media is screened of oversize
particles, and held in the reclaimer hopper for reuse.
Dust and fines are drawn through the reclaimer into the
dust collector. When the foot pedal is released, blasting
stops as the blast machine depressurizes, allowing
stored media to refill the machine.
1.5 Blast Machine and Remote Controls
1.5.1 The blast machine pressure vessel is
manufactured to American Society of Mechanical
Engineers (ASME) standards, as described in Section
VII, Div. 1, and carry a National Board certification. It is
the owners responsibility to maintain the integrity of the
vessel as may be required by some states. This may
include regular inspection and hydrostatic testing as
described in National Board Inspection Code and
Jurisdictional Regulations and /or Laws.
