Company Profile
THE CDS GROUP is widely regarded as the
world’s leading supplier of advanced process
equipment and drying systems for the
whole of the ceramics and allied industries.
The company was formed in 1983 at a
time when drying was viewed by many people
as a relatively low priority in the production
process. Since that time, however, the importance
of a well-designed and thermally efficient drying
system has been universally recognised as an
essential component in the manufacture of
ceramic products. New technologies have been
developed and tested, some with more success
than others, and the industry has shown a ready
acceptance of these advances. Whilst still
concentrating on its strengths and further
developing and improving its existing product
range CDS have continually been at the forefront
in developing alternative technologies for drying
ceramic products, most recently through this
development and proving of airless drying.
From the company’s headquarters in
Stoke-on-Trent, CDS provide a fully
comprehensive service to the industry from
conceptual design through to project
implementation and after-sales service. Ceramics,
with its constant search for high quality and
efficiency has become as diverse and demanding
as our own considerable expertise, which now
embraces a group of companies serving the
aspirations and requirements of the entire industry
on a worldwide basis. The industries served by
the CDS Group including the following:
• Sanitaryware
• Heavy Clay (including bricks and tiles)
• Tableware
• ‘HT’ Porcelain Insulators
• Industrial or ‘Special’ Ceramics
A major factor in the success of CDS
is the high percentage of repeat business, with
many of our customers returning to us as their
production increases or capital becomes available
for further modernisation. A sure sign of complete
customer satisfaction.
Although the company is based in the UK, the group’s activities are supported worldwide by a network
of local agents and regionally located partners, this regional representation again ensuring the highest
quality of service and support.
Included in the CDS Group are also companies specialising in the other disciplines of the
manufacturing proceed, so that now the group is perfectly equipped to offer either individual components
or the complete production line. These other companies within the group comprise:
• Bricesco Ltd - shuttle and tunnel kilns
• Thermic Design Ltd - casting and alternative drying systems
• CDS Fabrications - in-house manufacturing and specialist engineering
• Tuffplant - glass tempering kilns
• Kilns and Furnaces Ltd - kilns for ceramics, glass and metal
• Airless Process Systems LLP - energy solutions to the world including airless drying
When the strength of these companies product range is added to CDS’ unrivalled experience
in all forms of process drying and glazing lines, then all aspects of the manufacturing chain are available
from the group.
As the various sectors of the ceramics and allied industries have become so diverse, in recent
years the company has also arranged internally into a number of divisions, so that the unique needs
of each sector can be served in the most professional and competent manner. These divisions, all
staffed with experts in each industry comprise the following:
• CDS Technology
• CDS Tableware Technology
• CDS Projects - a total project management service
• CDS Group Parts and Maintenance Division - a complete spare parts and aftersales service
The range of products and systems is extensive and are fully illustrated in this brochure.
However, a brief introduction to CDS’ products are listed below:
• Batch loaded chamber dryers for all ceramic products, both ware and plaster moulds
• Continuous tunnel dryers for all ceramic products
• A comprehensive range of dryers for the tableware industry for holloware, flatware and moulds
• Environmental control systems for casting shops, particularly sanitaryware
• Pre-kiln glaze dryers
• Complete spray-glazing lines to incorporate glazing booths, clay inspection booths and dust collectors
• Airless dryers for all ceramic and non-ceramic products
All drying systems manufactured and supplied by CDS are ‘bespoke’ individually designed
against each customer’s requirements. There is no such thing as a standard drying system. As often
there are a number of options or alternatives available, CDS will always study the situation and offer
the most appropriate system, often providing the customer with these options for full consideration
and appraisal.
The scope-of-supply can range from a complete ‘turn-key’ package to a situation where only
‘key’ components are supplied by CDS, leaving the customer to supply the manufactured parts locally
against our comprehensive detailed engineering drawings.
Sanitaryware Chamber Dryers
In the case of drying new plaster moulds the
cycle times are generally in the range of
48-64 hours, where waste heat from the kiln
is often used to increase the thermal efficiency.
Moulds may be loaded by fork-lift truck on pallets
onto internal stillages, or by the use of cars or
conveyors.
Over the past twenty years, since the company was formed, CDS have designed and built more than
400 dryers, processing in excess of 72 million pieces of sanitaryware a year. The reasons for this success
are many and diverse; unrivalled product quality, operational reliability, technical innovation and continual
development and customer care, to name but a few.
Chamber dryers for ware and mouldsBatch drying for both greenware and plaster moulds is performed by the ‘HT’ Shuttle Dryer, which
offers drying speeds as fast ad 6-10 hours for sanitaryware (with ware entering the dryer at 25%
moisture contents and leaving below 1% moisture content). The faster cycle allows the dryer to
complete two drying cycles per day in most cases. The dryer is equipped with full humidity control
and humidity injection system, which protects the freshly cast ware from damage during the early
part of the drying cycle. The dryer also incorporates a unique system of air circulation which can be
automatically adjusted between 0-100% throughout the cycle. Combining this approach with the highly
insulated structure, has the additional benefit of making the ‘HT’ Shuttle Dryer the most thermally
efficient dryer available in the market.
The dryer is suitable for ware transported on trucks, buggies or skids, or can be fitted with
a wide range of automatic transportation systems. The design is based on a modular construction for
increased flexibility and future developments and can installed either as single or multiple units.

Environmental control in the casting shopAll too often the proper and concise control of the ambient conditions in the casting shop are
overlooked. Not only is this important for operative comfort, but is essential for thorough drying of
the ‘working’ moulds and ‘conditioning’ the cast pieces. The CDS environmental control system
is a multi-functional process, which combines space heating, ventilation, basic dust control as well as
mould drying/ware conditioning into an all embracing system. To accommodate a wide variation in
climatic conditions throughout the world, the system is designed in accordance with local data of
temperature and relative humidity. The system is equally applicable to all casting techniques including
manual casting, battery casting and capillary casting, both plaster and synthetic moulds.
Pre-kiln glaze dryersCDS manufacture a range of pre-kiln glaze dryers, designed to dry the glaze on the surface of the
sanitaryware before entry into modern fast-fire kilns. The glaze dryers can be installed either immediately
before the kiln or alternatively around the kiln return track. The heat for this process is normally ducted
into the dryer from the cooling zone of the kiln and is an excellent way of using a ‘free’ form of energy.
However, for increased efficiency, the dryers are usually fitted with a separate heat source, to the
switched-on automatically, should the waste heat be insufficient to satisfy the demands of the dryer.
To protect the ware from dust or other contaminates, the dryers are also fitted with both pre and
absolute air filters.

Sanitaryware
Airless drying for sanitarywareCDS are continually investing in new technology, both to improve the performance of the existing
range of dryers and also to develop new and different processes. The airless drying process can
be successfully applied to all ceramic products, including sanitaryware and is designed not to replace,
but complement, the highly successful range of fast process dryers already manufactured by CDS.
Suitable for drying the complete range of sanitaryware, the dryer is particularly suited to dry
the ‘luxury-end’ of the market including one piece wc combinations and also plaster moulds.
The ‘airless’ drying system offers ultra fast drying cycles, operates at high thermal efficiency
levels and offers a high potential for heat recovery.

Sanitaryware Fettling, Clay Inspection, Dust Collection
The basis design of the CDS clay inspection - fettling booths complies with the regulations
of the joint standing committee for the UK white wares industry as detailed in reg. 17(1) and protected
by British patent 833,608. The booths are manufactured from galvanised mild steel sheets and
finished in cream (outside) and white (inside) paint. The booths are designed in a wide range of sizes
to suit the sanitaryware processed. Either single or double width, with one or two turntables fitted,
the booths are illuminated by two vertical fluorescent lights manually operated. Downward air
movement is achieved by an axial flow fan mounted on top of the booth, creating a velocity of 0.5 m/sec
at grid level. Heavy scraps are collected in the under slung waste hopper and fine, air-borne dust is
carried in the ducted air stream to a separate dust collector.
The entire line comprising spray glazing booths, clay inspection booths, dust collectors
and conveyor may be supplied as a complete package, either with or without the associated ductwork.
CDS manufacture a wide range of dust
collectors for use with the clay inspection
booths, and other dust creating processes. The
dust collectors may either be close-coupled to
the clay inspection/fettling booths or be sized to
accept the requirements of several booths.
Dust laden air enters the collector
through a connection above the dust-collecting
bin, where large particles drop into the bin. The
air is then drawn upwards through the filter bag,
where fine particles are collected. Finally the clean
air is drawn through the fan to be discharged to
atmosphere. The fine dust deposit on the inside
of the filter bag is dislodged by an automatic
mechanism and falls into the collecting bin.
CDS manufacture a complete range of ‘ancillary’
equipment for the sanitaryware industry including
spray glazing booths (’wet’ and ‘dry-back’),
clay inspection booths, de-dusting booths and
clust collectors. All are designed and manufactured
in-house.
The equipment is manufactured in a
complete range of sizes and capacities to match
all product styles and production requirements.
The spray glazing booths are manufactured predominately from stainless steel and are available
in single or double width to accommodate either one or two turntables. A feature of the spray booths
is the secondary air filtration system, which allows the exhaust air to be vented directly to atmosphere.
The eliminator plates, manufactured from stainless steel, are removable for ease of cleaning and glaze
recovery. Glaze recovery may also be affected from the main water tank. The air filters are easily
accessed for cleaning or replacement. The air extraction volume is supplied by a single, centrifugal fan
mounted on top of the booth taking the exhaust air directly to atmosphere. Water is circulated by
means of a self-priming pump via UPVC piping. The booths are fitted with a hidden fluorescent light,
and are complete with integral control panel. Each glazing booth may be supplied with the complete
set of ancillary equipment; spray gun, anti-pulsation chamber, glaze pump and hoses.

As no two applications are the same, all CDS dryers and drying systems are custom-built to suit
each client’s unique requirements. We combine our own expertise and drying experience with the
client’s specialist knowledge of their products and material behaviour.
The scope-of-supply ranges from a complete turn-key supply project where all components
and engineering services are provided by CDS through to the supply of ‘specialist’ parts only. The
second option is particularly relevant in areas of the world where import duties are high and where
good quality, low cost, fabrication facilities are readily available, thus reducing overall capital expenditure
and freight costs.
A series of batch loaded chamber dryers for sanitaryware
Dryers for bricks, tiles & refractoriesCERAMIC DRYING SYSTEMS have, over the years, steadily achieved an impressive
track record within the industry for innovative design, in providing batch and tunnel
dryers to suit a wide range of products.
Each installlation is individually designed to accept the client’s preferred loading arrange,
whether by finger-car, trucks, pallets or direct setting onto kiln cars.
Precise control of temperature and humidity conditions together with the
provision of an intermittent air circulation system to the products, ensures that they are
dried ‘safely’, economically and in the shortest possible time.
The drying characteristics of the different bodies vary considerably. This, together with the
forming methods employed, are given careful consideration whenever the system is designed. In many
cases we carry out drying trials in order to fully assess and predict the behaviour of the body or
formed article for a fast-drying process.
In CDS Dryers all electric motors and moving parts are located external to the dryer. This
enables the higher temperatures to be used, necessary for rapid drying and ensures that they are
easily accessible for routine maintenance, promoting longevity and reliability.
With the application of modern techniques, it has been possible to dry soft mud bricks with
an initial moisture content of 25% within a 14 hour drying cycle, and at the same time considerably
reduce the running costs, compared to the original system.
Over the past few years, the industry, has seen production techniques move away from some
of the more ‘traditional’methods of brick production. At some brickworks one of these ‘traditional’
methods is to completely dry the bricks in a Hoffman or similar kiln without recourse to formal dryers.
However, in the quest for continuous improvement quality standards and increased yields, CDS have
worked closely with the manufacturers to provide new dryers and to improve these standards.

A major new innovation and breakthrough to
the production of tableware has been the
development of the airless drying system
that provides rapid mould release and whitehard
drying for most tableware products.
Using the patented technology, the dryer
has the ability to mould release in 2-3 minutes
and whitehard dry in a further 5-6 minutes.
Operating in this airless environment,
the dryer demonstrates that in excess of 170
fills are possible from conventional plaster moulds.
The airless technology drying system
will also provide rapid whitehard drying of
castware products such as tea pots, coffee pots,
soup tureens, figurines, etc. in typical drying times
of between 30 minutes to 2 hours depending
on the products.
They drying technology can be adapted to most
production requirements by providing continuous
conveyorized designs for vertical, overhead or
flatbed carrousel systems.
The dryer can be easily adapted to
operate with all types of forming machines from
a single to multi-head units, providing production
rates of between 8-16 pieces per minute.
A major benefit of the airless system
is the signification reduction in the quantity of
new moulds required, as the dryer typically uses
between only 40-60 moulds for carrousel type
dryers and 70-90 moulds for elevated swing-
tray dryers.
The ability to operate with synthetic type moulds as well as standard gypsum moulds on all types of
body formulae makes the airless system an extremely competitive option for the industry against
high capital, high maintenance systems.
Both batch and continuous dryers are available, all individually designed to suit customer
production procedures.

Porcelain Insulators
CERAMIC DRYING SYSTEMS is the
world’s leading supplier of advanced drying
systems for the ‘HT’ Porcelain industry.
In the field of process drying ceramic
products it is generally recognised that drying of
clay insulators is one of the most ‘difficult’ due
to their widely different shapes, sizes and varying
wall thickness. In order to ensure thorough and
consistent drying with minimal losses, it is
imperative that the process drying of these
products is performed to the highest standard
with close control over temperature, relative
humidity and air circulation. CDS ensure that all
these factors are carefully controlled, resulting in
a consistently dried product, at high yields, from
a highly thermally efficient dryer.
Including in our range of drying systems for the ‘HT’ Porcelain industry are:
• Conditioning dryers for clay extrusions prior to turning
• Continuous swing-tray mould release and leatherhard dryers for disc insulators
• Whitehard, high temperature, drying chambers for the complete range of ‘HT’ porcelain ware
• Dehumidification dryers for ‘special’ products
Each and every drying system is individually designed for the specific application, taking into
account the body type, body formation and process requirements.
Using ‘state-of-the-art’ technology, drying conditions are closely controlled throughout the
pre-determined cycle, with drying curves carefully planned to sympathise with the nature of the
product.
This criteria enables the following benefits to be achieved:
• Products may enter the dryer a relatively short period after forming, without the need for a ‘holding period’
prior to the drying process
• The drying process is not affected by local ambient conditions
• Increased utilisation of factory floor space
• Increased product yield
• Reduction in inventory or work in progress
• Improved product quality
• Reduced energy consumption by greater thermal efficiency
CDS has successfully applied the above principles
to ‘HT’ Porcelain dryers supplied to
manufacturers throughout the world including:
• Allied Doulton Insulators - UK
• Asian Insulator Co - Thailand
• Celico - Mexico
• Emco - Pakistan
• Hoechst Ceramtec - Germany
• WS Insulators - India
• Standard Insulators - Thailand
