Bibby Scientific Industrial Fluidised Baths
Clean Extruder Parts Safely & Efficently
Modern plastic producers spend ever-increasing amounts of money on more and
more complicated tooling which still has to be cleaned to maintain product quality.
Bibby Scientific approached this problem some years ago and now have a range of
equipment designed to remove unwanted material from production hardware
without damage to the part(s) being cleaned.
The Fluidised Bath is a thermal process that degrades plastic residues to carbon
and comes away from the bath as CO2.
This fast cleaning process enable costly machinery to be put back into production
with the minimum delay.
Baths operate from a factory air supply or if required inert gases such as nitrogen,
full range of fume treatment apparatus is available.
BURN-OFF FLUIDISED BATHS A fluidised bath consists of a loosely packed
mass of solid particles through which an
upward flow of air is passed. In this fluidised
state the particles become mobile, and the bath
as a whole displays many of the properties of
a liquid. However, since the bath is composed
of tiny inert aluminium oxide particles, freezing,
boiling and evaporating are totally eliminated.
These advantages make fluidised baths a very
attractive, pollution free, safe alternative to oil,
salt and molten metal baths.
Bibby Scientific produce rugged units for the plastics,
paint, rubber and associated industries. These
industrial fluidised baths are ideal for cleaning
residual plastic material from dies, breaker
plates, spinnerretes, etc. They are also widely
used for removing epoxy powder paint
coatings and for reclaiming painted, coated
and bonded components.
Fast: Most parts are thoroughly cleaned in 20-
30 minutes.
Temperature range: 50degC - 600degC
No damage to expensive parts: The nonabrasive,
non-corrosive medium eliminates the
wear and damage so often caused by manual
cleaning. Uniform bath temperature prevents
distortion.
Safe: Dry, inert medium.
Labour free: The cleaning process is entirely
automatic.
Reliable: Heavy stainless steel construction
with external heaters for long continuous
service.
Construction: Rugged stainless steel inner
container and porous plate for heavy industrial
use. Protected controls.
Fume extraction: All units are available with
peripheral fume extraction systems to ensure the
safe removal of combustion products whilst
maintaining access to the bath. Heavy duty
stainless steel mesh baskets are available.
Auto air units come complete with an
automatic air adjustment system and flowmeter
for visual monitoring of the airflow through the
bath see ordering information.
FUME CLEANING
For those installations where it is desirable to
have an independent system for cleaning fumes
from the burn-off process and in order to assist
customers in complying with local requirements
for environmental pollution. Bibby Scientific have
developed three fume treatment systems.
CYCLONE
This efficient wall mounted unit can extract more
than 99% of any fluidising medium that may be
carried over into the bath exhaust system.
Safe: No moving parts
Economical: Requires no power, other than
connector to extraction fan.
Efficient: Specially designed for optimum
combination of air flow and pressure drop.
Flexible: Compatible with all Bibby Scientific fluidised
baths and fume cleaning equipment.

AFTERBURNER
The system has been designed to eliminate
virtually all visible smoke and fumes using a
powerful flow-through burner operating from
mains or bottled gas. No secondary fan is
required for the combustion air.
Safe: Designed to comply with British Gas
Council and most other regulations.Fail safe
systems include ultra-violet flame detection and
double solenoid control of inlet gas.
Effective: Exhaust stack emission is in
accordance with threshold limit values (TVL's)
adopted by the American Conference of
Governmental Industrial Hygienists (AGGIH) at
its annual conference in 1976. In the UK these
TVL's are reproduced in Guidance Note EH15/76 from the Health and Safety Executive.
Compact: Minimum amount of floor area
required.
Economical: Gas is consumed only when the
equipment is in use.
Quick to install: The free standing unit needs
only to be connected to gas and mains
electricity.
Serviceable: Service can be carried out easily
by the user.
Easy to operate: The afterburner has few
operator controls and is simple and easy to
operate.
SCRUBBER
This powerful electrically driven unit prevents
corrosive acids and other soluble noxious fumes
(especially hydrochloric acid and harmful byproducts
of PVC and other halogenated
polymers) from being emitted into the
atmosphere.
Compact: Free standing unit with 100mm
venturi.
Compatible: The scrubber is compatible with the
afterburner and most Bibby Scientific fluidised baths.
Serviceable: the unit is easily installed inside or
out of doors, requiring only mains electricity and a
convenient water supply. It can be easily serviced
and maintained by the user.
Inexpensive: Only power requirement is to run
the water recirculating pump.
Flexible: Optional caustic make-up tank with
programmed or manual pH control. Water feed
and discharge can also be manual or automatic.
