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.

Some current clients using the airless dryer for

their production include:

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
