PENBERTHY MODEL GSA ANOLODER FOR AN-FO (AMMONIUM NITRATE - FUEL OIL) BLASTING

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

1 ABOUT THE MANUAL

This manual has been prepared as an aid and
guide for personnel involved in installation or
maintenance. All instructions must be read and
understood thoroughly before attempting any
installation, operation or maintenance.

Emerson does not have any control over the
manner in which its anoloder is handled,
installed or used. Emerson cannot and will not
guarantee that the anoloder is suitable for or
compatible with the user's specific application.

WARNING

The anoloder handles prilled ammonium nitrate/
fuel oil mixtures at high pressures. If proper
procedures are not followed, the operator could
experience a sudden blast of high pressure dust.
The operator should wear protective clothing and
safety glasses before attempting to operate or
perform maintenance on the anoloder. Failure
to do so can result in severe personal injury and
property damage.

2 INTRODUCTION

Penberthy model GSA is a portable jet loader
used in AN-FO blasting. The anoloder uses a
high pressure air stream to educt powder into
a discharge flow stream. The powder exits
the nozzle at a high velocity and density to fill
predrilled holes.

2.1 System description

The Penberthy anoloder consists of five basic
components. Use the exploded parts view in
Section 9 as additional reference material.

Ejector- aluminum ejector uses the high
pressure air to create a pressure differential.
When activated by the remote control valve, the
air stream pulls the powder from the container
and blows it into predrilled holes.

Canister - plastic canister contains the prilled
powder and acts as a hopper to direct the
powder flow to the ejector. The canister has
a stainless steel fluidizing screen to deter
bridging of the powder as it nears the suction
port of the ejector. Aluminum legs are bolted to
the canister to make it sturdy on level ground.

Carrying strap - canvas strap makes the
anoloder portable. The anoloder is light enough
that most operators can carry the units to
various work and powder loading areas.

2.2 Assembly

Attach the control hose to the ejector body by
screwing-in the male NPT connection on the
end of the air valve control assembly. Attach
the black loading hose to the outlet of the
ejector diffuser using the hose clamp supplied.
Emerson recommends attaching a band of
adhesive tape near the end of the loading hose
to indicate to the operator that the end of the
hose has been reached and the drilled hole is
nearly full.

Attach the air hose to the 1" NPT ejector inlet.
An adapter fitting (not supplied) for air supply
hose connection must be screwed into the
1" NPT connection. A lobe on the body of the
ejector near the loading house provides a place
to earth ground the ejector using a nut, bolt and
grounding strip (strip not included).

WARNING

Air placement of AN-FO mixtures can result in
a hazard due to generation of static electricity.
The 'conductive' type loading hose supplied with
the model GSA anoloder in conjunction with
grounding strips will generally dissipate the static
charges as they are generated. To ensure safe
operation applicable codes and mining regulations
must be followed without exception. Neglecting to
compensate for potential static electricity buildup
could result in an unexpected explosion, resulting
in severe personal injury and property damage.

3 AVAILABLE MODELS

All anoloder models have a 1" female NPT air
line connection to the ejector. The loading hose
is available in a standard 25ft length or 100 ft
length. Penberthy anoloders are available in
three different sizes. The model size determines
the loading hose size. The GSA ⅝" has a ⅝"
diameter hose. The GSA ¾" has a ¾" diameter
hose. The GSA 1" has a 1" diameter hose.

Remote control hose/valve - aluminum valve
allows the operator to control the operating
air pressure by pulling the handle. The handle
activates the air flow stream by bleeding a portion
of the air flow which allows an internal piston to
move and open the air orifice in the ejector.

Loading hose - static-resistant plastic hose
directs the air and powder mixture into the
drilled hole.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

4 INSPECTION

Safety instructions

On receipt of a Penberthy Model GSA anoloder,
check all components carefully for damage
incurred in shipping. If damage is evident or
suspected, do not attempt installation. Notify
the carrier immediately and request a damage
inspection.

Penberthy Model GSA anoloder comprises
(1) canister with attached carrying strap and
ejector, (1) remote control valve/hose assembly,
(1) loading hose, (1) clamp, (1) grounding
bolt and (1) grounding nut. Confirm that the
delivered Model GSA anoloder: 1) matches the
appropriate size and model on the purchase
order and 2) accommodates the actual
operating conditions at the installation site.

5 OPERATION

Only qualified, experienced personnel who are
familiar with AN-FO blasting equipment and
thoroughly understand the implications of the
tables and all of the instructions should operate
the anoloder. The anoloder is operated with
30 to 110 psig (210 to 760 kPaG) compressed
air. For maximum performance keep pressure
losses between air main and unit to a
minimum. Dirt, mud and other foreign matter
must be kept out of the air supply line.

5.1 Testing

Safety glasses, gloves and protective clothing
should be worn when testing the Model GSA
anoloder. Connect the air hose to the anoloder
and squeeze the hand control valve two or three
times to test valve operation. The unit can be
expected to load properly if air blows freely out
loading hose.

5.2 Filling and operating

Pour the AN-FO into the canister to within a
few inches of the top (approximately 25 lbs),
or up-end the entire bag and leave it in the
container. Insert loading hose into drill hole
to predetermine the length of hose needed to
reach the bottom of the hole. Back the hose out
of the hole one to four feet from the bottom.

decreasing this distance to one foot may cause
some of the AN-FO particles to be blown out of
drill hole.

6 MAINTENANCE

Use only qualified, experienced personnel who
are familiar with this type of equipment and
thoroughly understand all the instructions in
this manual. Ammonium nitrate is a corrosive
and hygroscopic compound which can
clog pneumatic loading equipment quickly.
Maintenance is an important factor in ensuring
safe anoloder operation.

6.1 Cleaning

Empty any AN-FO left in the anoloder canister.
Wash down the anoloder and other exposed
equipment with water. Pour water into the
canister and use the control valve to blow air
through the ejector until all water has been
removed. A screen is provided in the air inlet
of the ejector to prevent foreign matter from
entering the ejector. The air strainer should be
removed and cleaned regularly.

In some cases it will be advisable to clean
the ejector body and parts with naphtha
(petroleum spirits) at regular intervals to
minimize corrosion. The ejector should only
be dismantled in a proper maintenance area,
using the following procedure:

• unscrew ejector bonnet nut

• remove spring, piston and piston O-ring

• remove air strainer retainer ring and air
strainer screen

• snap off diffuser shroud and unscrew ejector
diffuser one-half turn

• clean body and parts with naphtha (petroleum
spirits)

• dry parts with a clean cloth and blow out body
with compressed air

•

tighten diffuser, reassemble and test operation

Safety instructions

Improper technique could result in a sudden
blow-back of AN-FO from the drilled hole
during loading. The operator should stand
to one side of the drilled hole, never directly
in front. Failure to avoid hole openings could
result in irritating and potentially harmful
AN-FO material covering the operator.

The operator should stand one to four feet from
the drill hole when grasping the loading hose.
Increasing this stand-off distance beyond six
feet will decrease the loading density, while
