FLOW CONTROLS
4.1
Control of Abrasive Separation
As the initial charge of abrasive progressively breaks down into a working mix, further
adjustments may be necessary to avoid loss of good abrasive. It is recommended that
close monitoring of discharges be carried out at regular intervals during the first 40 hours
of use.
4.1. Models fitted with regrader unit
It is advisable when introducing a new grade or type of media into the blast system to
check the deposits in the dust collector drawer and make the necessaary adjustments
accordingly.
4.1.1.
Re-usable particles in dust collector:-
4.1.1.1. At the regrader, unscrew knob 'A' one full turn, then carefully screw knob 'B' is not
over tightened as this will damage the deflector plate.
4.1.1.2. After the next blasting and recovery operation has been completed, check the dust
collector drawer contents and repeat operation 4.1.1.1. until only unwanted fines
are collected.
4.1.2. Unwanted fines returned to the nozzle:4.1.2.1. Unscrew knob 'B' one full turn then carefully screw knob 'A' until resistance is
detected. DO NOT over tighten as this will cause damage to the deflector plate.
4.1.2.2. Repeat operation 4.1.2.1. after each subsequent recovery operation, until required
level of fines removal is achieved.
4.2
Models with dust collectors only
4.2.1 Good abrasive in dust collector drawer: - Slightly close dust collector damper.
TSOM 314C

Page 10 of 20
.2
Dusty conditions within the blast cabinet:- slightly open dust collector damper.
N.B. Should excessive build up of dust be found on the collector filter element also
check function of cleaning mechanism
IMPORTANT NOTICE: THE INLET DAMPERS ON THE DUST COLLECTOR SHOULD
BE IN THE FULLY OPEN POSITION FOR MOST COMMON ABRASIVE TYPES AND
GRADES. THESE DAMPERS ENABLE MORE FINITE SEPARATION TO BE
ACHIEVED WHEN FINE GRADES OF LIGHTER MATERIAL IS BEING RECYCLED.
4.3
Control of Abrasive Metering
Normal average setting of the rubber cap is shown in the diagram below. Further slight
adjustment of the cap may be necessary for certain types and grades of abrasive to
achieve a balanced lean mixture at the nozzle:.1
Abrasive pulses/surges through the nozzle:Increase air inlet by adjusting cap upwards.
.2
Abrasive mixture intermittent or too lean at the nozzle:Decrease air inlet by adjusting cap downwards.

MAINTENANCE
All blast cleaning equipment is self destructive when in operation, therefore for safety and
efficiency it is essential to carry out a regular preventative maintenance programme. This
programme is divided into daily, weekly and monthly schedules, as a guide to the
compilation of your maintenance schedule.
Warning: Ensure that the electricity supplies are switched off at the isolator
supply also that the compressed air is turned off at the compresses air supply
valve and the air lines are depressurised, before any maintenance is carried out.
Maintenance work must only be carried out by suitably trained, competent, authorised
persons.
DAILY
1.
Check all hoses, couplings and gaskets for evidence of wear and replace if
necessary.
2.
Check that all couplings are correctly coupled. Blast hose couplings must be
secured with split pins through the holes provided.
3.
Check the condition of the nozzle holder gasket and replace if necessary.
4.
Check that the blast hose runs in loose curves. Tight curves and kinks in the blast
hose cause turbulence and accelerated wear.
5.5.
Remove empty and replace the dust collector dust drawer.
WARNING: NEVER INSPECT THE DUST COLLECTOR DRAWER, DUST FILTER OR
RECLAIM WHILST SMOKING OR ALLOW ANY NAKED LIGHTS IN THEIR
PROXIMITY. DUST CONCENTRATIONS CAN BE COMBUSTIBLE AND
HAZARDOUS TO HEALTH. RESPIRATORY PROTECTION SHOULD BE USED.
WEEKLY
5.6.
5.1. to 5.5. Plus:-
Check the condition of the water separator. Remove and clean the filter bowl
and element if necessary with mild detergent and water.
