4. Sanitaryware Chamber Dryers
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.

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.

5. Sanitaryware Tunnel Dryers
Tunnel dryers for continuous production
CDS are the world’s leading experts in the design and implementation
of tunnel dryers for sanitaryware and have many successful installations
operating throughout the world. Similar fast drying principle as are
employed in the ‘HT’ Shuttle Dryer once again the dryer is designed
to accept all forms of conveyorised or alternative transportation systems.

Environmental control in the casting shop
All 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
Environmental control and exhaust ductwork in the casting shop
manual casting, battery casting and capillary casting, both plaster and synthetic moulds.
Mould drying enclosures for closets

Pre-kiln glaze dryers
CDS 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

Airless drying for sanitaryware
CDS 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.

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

CDS dust collectors
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

carried in the ducted air stream to a separate dust collector.

and conveyor may be supplied as a complete package, either with or without the associated ductwork.
